Building material estimation system, management server thereof and building material estimation method

Cross reference to related applications

The present application claims priority from japanese patent application 2019-.

Technical Field

The present invention relates to a building material estimation system, a management server thereof, and a building material estimation method, for determining the number of building materials such as tiles and panels to be distributed to the floor and wall of a building.

Background

In general, when building materials such as tiles are arranged on a wall surface of a building, the area of an arrangement area is calculated, the area is divided by the area of the building materials, and the area is multiplied by a loss rate, and a grid is displayed and counted to calculate the required number. Further, in recent years, a method and a system have been proposed which inputs arrangement condition data such as the size of the building materials, drawing data of the arrangement area into a computer, displays the state of the building materials when arranged in the arrangement area in the computer, and automatically calculates the required number of the building materials (refer to japanese patent laid-open nos. 2002-.

However, in an actual building, there are areas such as windows, pillars, doors, etc. where no building material is arranged in the arrangement area. In this case, if the required number of building materials is obtained by the above-described method and system, the amount of the area where the building materials are not arranged is also calculated as the required number of building materials, and therefore, the required number of building materials cannot be accurately obtained.

Detailed Description

(outline of building Material evaluation System)

As shown in fig. 1A, the building material estimation system 1 of the present embodiment is a system that can perform editing processing such as addition/deletion, change, and movement on the building materials 31 in a unit of one for a part or all of the building material sets 3 after displaying an image in which the building material sets 3 composed of a plurality of kinds of building materials 31 are allocated to the construction area 21 such as a ceiling, a wall, and a floor in a predetermined arrangement pattern on the display device 18.

Specifically, the building material estimation system 1 includes a database unit 11, and the database unit 11 stores a design drawing file including design drawing data of a building such as a house or a building, a building material specification file including size data and shape data of the building material 31, and a pattern file including arrangement pattern data of the building material 31.

Here, the "design drawing" is a drawing mainly aiming at expressing the overall form of a building, the layout of rooms, and other external design, and may be exemplified by a layout drawing, a plan view, a roof plan view, a front view, a sectional view, an expanded view, and the like. The design drawing may be a drawing in which a drawing such as a leaflet used for house sales or the like is converted into electronic data by a scanner or a camera, in addition to CAD data.

The "building material specification document" may include various data such as material/product name, part number, price, and sales address, in addition to the size data and shape data of the building material 31. As the building material 31, a rectangular panel such as a rectangle is exemplified, but it may have another shape such as a circle or a polygon, or may have plastic deformation or elastic deformation properties if it is formed of a material capable of retaining the shape. The building material specification is preferably automatically updated at an appropriate time from a website such as a building material manufacturer or a building material selling company via the internet. In addition, as the arrangement pattern data, a lattice arrangement, a width offset arrangement, a herringbone arrangement are exemplified. The arrangement pattern data is not limited to the three examples of the grid arrangement, the width offset arrangement, and the herringbone arrangement, and it is preferable that the arrangement in which the various building materials are regularly combined can be registered in advance. For example, as shown in fig. 1B, a structure in which the arrangement groups in which the a building materials and the B building materials are alternately arranged in the horizontal direction are stacked in the vertical direction may be registered in advance, and as shown in fig. 1C, a structure in which the a building materials and the B building materials are alternately arranged in the horizontal direction to form the 1 st arrangement group, the B building materials and the C building materials are alternately arranged in the horizontal direction to form the 2 nd arrangement group, and the 1 st arrangement group and the 2 nd arrangement group are alternately shifted in the vertical direction and stacked in the long direction may be registered in advance.

In addition, the building material estimation system 1 has a basic diagram acquisition unit 12, and the basic diagram acquisition unit 12 acquires a basic diagram 2 including a construction area 21 in which the building material 31 is to be arranged and stores the basic diagram 2 in the memory 55. When the building material set 3 is determined in a state where the construction area 21 is not included in the basic diagram 2, the entire design diagram in the basic diagram 2 becomes the execution area 21. The basic diagram acquiring unit 12 has an access function of accessing the database unit 11 and acquiring at least the design diagram data, and a basic diagram generating function of generating the basic diagram 2 from the design diagram data. The base map generating function is a function capable of setting a construction area 21 to be constructed by a constructor on a base map 2 indicating all or a part of a floor surface, a wall surface, a ceiling surface, and the like, based on design map data input from a scanner, a camera, or the like, in addition to design map data acquired from the database unit 11.

The base map acquisition unit 12 has a construction area setting function of setting a plurality of construction areas 21 on the base map 2 stored in the memory 55 by the operation of the external device 19. The construction area setting function may be a function of the construction area setting unit 53 other than the function of the base map acquiring unit 12. The construction areas 21 may be arranged in a distributed manner so that the plurality of construction areas 21 do not overlap each other, or a part or all of the other construction areas 21 may be arranged to overlap a specific construction area 21. For example, the following states are shown in fig. 1D: on the ground surface of fig. 2, 1 st to 3 rd construction areas 21a to 21c are set, and the entire 2 nd construction area 21b is overlapped and arranged in the 1 st construction area 21a, and the 3 rd construction area 21c is arranged in a dispersed manner with respect to the 1 st construction area 21a and the 2 nd construction area 21 b. Fig. 1E shows a state in which the 4 th to 6 th construction areas 21d to 21f are independently arranged in the vertical direction (vertical direction) on the wall surface of fig. 2. Fig. 1E is an expanded view showing a wall surface in the direction of an arrow (visual direction) viewed from the inside of the room to the outside of the room from point X1 to point X2, and shows a state in which openings such as windows are formed as the arrangement avoidance areas 211 at two locations in the wall surface. A method of displaying the wall surface in a plan view as an expanded view will be described later.

The building material estimation system 1 further includes: a layout drawing generation unit 13 that develops the building material set 3 in which the plurality of building materials 31 are arranged in the memory 55, and generates a building material layout drawing 3A formed so that the building material set 3 covers the construction area 21; a display control unit 14 that controls the display device 18 so as to display the construction material layout fig. 3A and the construction area 21 of the basic fig. 2 in an overlapping manner; an editing unit 15 that executes an editing process of deleting a part of the building material group 3 in the building material arrangement diagram 3A in building material units in accordance with an instruction from the external device 19; a counting unit 16 for calculating the number of building materials 31 constituting the building material set 3 in the building material arrangement diagram 3A; the output unit 17 outputs the number of the building materials 31 to the outside. The output unit 17 may be a display device 18 that displays the number of the building materials 31, or may be another information processing device. When outputting the data format to the outside, the output unit 17 preferably outputs the data format with an extension set by the operator. For example, when an extension of Excel (registered trademark) is set, the data of the number list of the building materials 31 is output as the extension of Excel (registered trademark).

Thus, the building material estimation system 1 can precisely determine the required number of building materials 31 by deleting a part of the building material group 3 in building material units according to a designation from the outside, and thus can finely adjust the number of building materials 31. Here, "designation from the outside" means designation by the operator operating an external device 19 such as a mouse or a touch panel. The editing unit 15 preferably executes various editing processes such as editing processes for deleting building material units, editing processes for adding building material units, and editing processes for moving or changing building material units, in addition to the editing processes for deleting building material units. The details of the editing process will be described later.

Further, in the building material estimation system 1, it is preferable that the base map acquisition unit 12 acquires a base map 2 having a plurality of construction areas 21, the layout map generation unit 13 generates a building material layout map 3A for each construction area 21, and the editing unit 15 executes an editing process for each building material layout map 3A. In this case, the editing process is executed for each of the building material layout diagrams 3A of the plurality of construction areas 21, and thus the editing work can be performed quickly.

Thus, for example, as shown in fig. 1D, when the building material group 3a is disposed in the 1 st construction area 21a, the building material group 3a is disposed with the horizontal building materials oriented in the horizontal direction, and the building material group 3b is disposed in the 2 nd construction area 21b, the building material group 3b is disposed with the vertical building materials oriented in the vertical direction, the editing operation can be performed for each of the

building material groups

3a and 3 b. For example, as shown in fig. 1E, different building materials can be arranged in the 4 th to 6 th construction areas 21d to 21f, respectively, and an editing operation can be performed.

It is preferable that, when there are a plurality of construction areas 21, the construction material layout diagram 3A of the construction material group 3A in the construction areas 21 can be formed at once by designating any one or more construction areas 21 and performing an operation of selecting the construction material 31 used in the designated construction area 21 after all the construction areas 21 are subjected to the operation. Here, "selecting the building material 31" means selecting the type, size, vertical arrangement, horizontal arrangement, inclined arrangement, and the like of the building material 31.

In this case, as shown in fig. 1E, for example, after different building materials are respectively allocated to the 4 th to 6 th construction areas 21d to 21f, the building material layout diagrams of the

building material groups

3c, 3d, 3E in the 4 th to 6 th construction areas 21d to 21f can be formed at once by a predetermined opening and closing operation. As a result, selection of the building material 31 to be used in all of the 4 th to 6 th working areas 21d to 21f can be completed in advance, and therefore, selection errors of the building material 31 in the 4 th to 6 th working areas 21d to 21f can be reduced.

The building material estimation system 1 can also be realized by a building material estimation program installed in the information processing device, in which a part of the functions of the processing units are realized. For example, as shown in fig. 2, the building material estimation program is configured to cause the computer of the information processing device to function as a basic diagram acquisition unit 12, a layout diagram generation unit 13, a display control unit 14, an editing unit 15, a counting unit 16, and an output unit 17. That is, the building material estimation program causes the computer to execute: a base map acquisition process (S1) of acquiring a base map 2, the base map 2 including a construction area 21 where the building material 31 is to be arranged; a layout creation process (S2) of creating a building material layout fig. 3A, in which the building material layout fig. 3A is a diagram in which a building material group 3 in which a plurality of building materials 31 are arranged is formed so as to cover the construction area 21; a display control process (S3) for controlling the display device 18 so that the building material layout fig. 3A is displayed superimposed on the construction area 21 of the base fig. 2; an editing process (S4) of deleting a part of the building material group 3 in the building material arrangement diagram 3A in building material units in accordance with a designation from the outside; a counting process (S5) of determining the number of building materials 31 constituting the building material set 3 in the building material arrangement diagram 3A; and an output process of outputting the number of the building materials 31 to the outside. The editing process (S4) includes processes such as addition/deletion, change, and movement of the building material 31 for a part or all of the building material group 3 in one unit. The building material estimation program may be distributed in a state of being stored in a storage medium such as a CDROM or a USB memory, or may be distributed via a bidirectional communication network such as the internet or a unidirectional communication network such as television broadcasting or a communication line.

(function of correcting the number of building materials in the layout avoidance area)

As shown in fig. 1F and 1G, in the arrangement diagram creation process (S2), when the arrangement-avoiding region 211 in which the building material 31 is not arranged such as an opening exists in the construction region 21, the building material arrangement diagram 3A of the building material group 3 excluding the arrangement-avoiding region 211 is formed. Here, fig. 1F shows a construction material group 3 having a width that is displaced in the construction area 21 having the arrangement avoidance area 211 therein, and fig. 1G shows a construction material group 3 having a herringbone arrangement in the construction area 21 having the arrangement avoidance area 211 therein.

In this case, the counting process (S5) subtracts the number of the building materials 31 disposed in the arrangement-avoiding region 211 from the total number of the building material groups 3 (building material arrangement diagram 3A) at least partially overlapping in the construction region 21, and displays the subtracted total number on the screen. Further, the total number before subtraction and the subtraction number (the number of the building materials 31 disposed in the arrangement-avoiding region 211) may be displayed on the screen together with the total number after subtraction.

The building material estimation system 1 having the building material correction function, the building material estimation method, and the management server of the building material estimation system are configured as follows.

The building material estimation system 1 includes: a basic diagram acquiring unit 12 that acquires a basic diagram 2 and stores the basic diagram in the memory 55; a construction area setting portion 53 that sets the construction area 21 in which the building material 31 is to be laid out on the base map 2 stored in the memory 55 by an operation of the external device 19; a avoidance specifying unit 20 that specifies an arrangement avoidance region 211 in which the building material 31 is not arranged in the construction region 21 by an operation of the external device 19; a layout generating section 13 for developing the building material set 3 in which the building material 31 is arranged in the memory 55 and generating a building material layout in which the building material set 3 covers the construction area 21; a display control unit 14 that controls the display device 18 to display the building material layout drawing, the construction area 21, and the layout avoidance area 211 in an overlapping manner; a counting unit 16 for obtaining the number of construction materials 31 at least partially overlapped in the construction area 21 and the number of avoidance of the construction materials 31 completely included in the arrangement avoidance area 211 from the construction material group 3, the construction area 21, and the arrangement avoidance area 211 developed in the memory 55, and obtaining the number of the construction materials 31 constituting the construction material group 3 in the construction material arrangement diagram by subtracting the number of avoidance from the number of construction; and an output unit 17 for outputting the number of the building materials 31 to the outside.

A management server of a building material estimation system includes: a memory 55 for storing various data including data relating to the number of the building materials 31; and a controller that performs the following processing: a basic map acquisition process (basic map acquisition unit 12) of acquiring a basic map 2 and storing the basic map in the memory 55; a construction area setting process (construction area setting section 53) of setting the construction area 21 in which the building material 31 is to be laid out on the base map 2 stored in the memory 55 by operating the external device 19; avoidance specifying processing (avoidance specifying unit 20) of specifying the arrangement avoidance region 211 in which the building material 31 is not arranged in the construction region 21 by operating the external device 19; a layout generating process (a layout generating unit 13) of developing the building material set 3 in which the building material 31 is laid out in the memory 55 and generating a building material layout formed so that the building material set 3 covers the construction area 21; a display control process (display control unit 14) of controlling the display device 18 so that the building material layout drawing, the construction area 21, and the layout avoidance area 211 are displayed in an overlapping manner; a counting process (counting unit 16) of obtaining the number of construction materials 31 at least partially overlapped in the construction area 21 and the number of avoidance of the construction materials 31 completely included in the arrangement avoidance area 211 from the construction material group 3, the construction area 21, and the arrangement avoidance area 211 developed in the memory 55, and obtaining the number of the construction materials 31 constituting the construction material group 3 in the construction material arrangement diagram by subtracting the number of avoidance from the number of construction; the output process (output unit 17) outputs the number of the building materials 31 to the outside.

According to the construction material estimation system 1, the construction material estimation method, and the management server, the required number of construction materials 31 can be accurately obtained by subtracting the number of avoidance operations from the number of construction operations.

The building material estimation system 1 realizes a building material estimation method capable of determining the number of building materials to be arranged in a construction area 21 (all or part of a floor surface, a wall surface, and a ceiling surface) of a building (a house, a building, or the like). Specifically, the building material estimation method includes the steps of: a base map acquisition step of acquiring a base map 2, the base map 2 including a construction area 21 in which a building material 31 is to be arranged; a layout creation step of creating a building material layout 3A, the building material layout 3A being formed such that a building material group 3 in which a plurality of building materials 31 are arranged covers the construction area 21; a display control step of controlling the display device 18 to display the construction material layout fig. 3A and the construction area 21 of the basic fig. 2 in an overlapping manner; an editing step of executing an editing process of deleting a part of the building material group 3 in the building material arrangement diagram 3A in building material units in accordance with a designation from the outside; a counting step of obtaining the number of the building materials 31 constituting the building material group 3 in the building material arrangement diagram 3A; and an output step of outputting the number of the building materials 31 to the outside.

(outline of building Material estimation System: management Server)

In the building material estimation system 1, the processing units 11 to 19 are connected by wire/wireless communication so as to be capable of data communication. A part or all of the processing units 11 to 19 may be connected via the Internet. The processing units 1 to 19 may be mounted on 1 information processing device, or may be mounted in a distributed state on a plurality of information processing devices.

For example, as shown in fig. 3, in the building material estimation system 1, all of the processing units 1 to 19 may be mounted on the management server 22 which is 1 information processing device. Specifically, the management server 22 of the building material estimation system 1 includes: a base storage device 221 (database unit) that stores a base map 2 including a construction area 21 in which the building material 31 is to be laid; a communication device 222 that accesses the external terminals 23A to 23D; a controller 223. The controller 223 executes the following processing: a base map acquisition process of acquiring a base map of base map 2 from base storage device 221; a layout creation process of creating a building material layout fig. 3A, the building material layout fig. 3A being formed in such a manner that a building material group in which a plurality of building materials 31 are arranged covers the construction area 21; a display control process of controlling the external terminals 23A to 23D so that the building material layout fig. 3A is displayed to overlap the construction area 21 of the basic fig. 2; an editing process of executing an editing process of deleting a part of the building material group 3 in the building material arrangement diagram 3A by building material unit, in accordance with a designation from the external terminals 23A to 23D; a counting process of calculating the number of the building materials 31 constituting the building material set 3 in the building material arrangement diagram 3A; and an output process of outputting the number of the building materials 31 to the external terminals 23A to 23D. In this case, the management server 22 transmits the execution result of the editing process or the like to the external terminals 23A to 23D, and the display device 231 of the external terminals 23A to 23D can check the execution result. In this case, the external terminals 23A to 23D can function as the external device 19. The management server 22 is loaded with the memory 55 of fig. 1A.

In addition, the building material estimation system 1 may be configured such that a part of the processing units 11 to 19 is mounted on the

external terminals

23C and 23D, and the

external terminals

23C and 23D cooperate with the management server 22 to execute editing processing or the like that places a large burden on the computer on the management server 22, and the execution result is checked by the

external terminals

23C and 23D. For example, in the external terminal 23C, the controller 232 executes basic diagram acquisition processing, layout diagram generation processing, display control processing, editing processing, counting processing, and output processing, and other processing can be evaluated by accessing the management server 22. In the external terminal 23D, the controller 232 executes display control processing, editing processing, counting processing, and output processing, and can perform estimation processing for other processing by accessing the management server 22. Here, as the external terminals 23A to 23D, general desktop or portable information processing devices, portable terminal devices such as smartphones, and the like are exemplified.

(building material estimation System: editing processing)

The editing process such as addition/deletion, change, and movement performed for each building material unit will be described in detail.

Fig. 4A and 4B are views for explaining an editing process of deleting a part (individual building material 31) of the building material set 3 in fig. 3A in building material units in accordance with a designation from the outside. Further, the designation from the outside can be performed by an icon by a mouse operation, or can be performed by an operator touching a touch panel provided on the display screen of the building material arrangement fig. 3A. In the deletion method, the building material 31 to be deleted is designated, and a deletion button, not shown, is pressed at the designated position to delete the building material, and the building material 31 is moved from the designated position to the outside of the building material arrangement fig. 3A by dragging, and is moved into the trash icon 181 appearing at the time of the movement to delete the building material. The deletion may be performed by detecting a click on the building material 31 to be deleted. Specifically, the click on the building material 31 to be deleted is detected, and the display state of the building material 31 is switched to the non-display state after the deletion of the building material 31 is completed, thereby notifying the deletion of the building material 31. Then, when the click is detected again at the position of the deleted building material 31, the deleted building material 31 is restored, and the restoration of the building material 31 is notified by switching the display state of the building material 31 from the non-display state. That is, the building material 31 is repeatedly erased (non-display state) and restored (display state) by a repeated operation of one click detection.

The number of deletions of the building material 31 is subtracted from the total number of building materials 31 constituting the building material arrangement diagram 3A, and the total number of the deleted building materials 31 is displayed on the screen. The number of deletions of the building material 31 may be displayed on the screen together with the total number of the deleted building materials 31. The screen display is preferably displayed in a manual input field indicating that the screen display is deleted by "manual input". In this case, it is possible to easily check the data including the total number and the number of deletions of the building material 31 in the subsequent inspection.

The specified building material 31 is preferably displayed so as to be emphasized so that the operator can easily distinguish it. The highlight display is a display state in which the display mode is different from that of the building material 31 by one or more combinations of color, brightness, pattern, and the like. In order to facilitate the discrimination by the operator, the area from which the building material 31 is deleted is preferably highlighted in a display state different from that of the specified building material 31.

It is preferable that the specified building material 31 can be angularly changed at the specified position and can be angularly changed at the predetermined position after the movement. Thus, the building material 31 deleted from the designated position can be completely deleted by the trash icon 181, or can be temporarily retained outside the building material arrangement fig. 3A, and can be arranged in another position of the building material set 3 as needed.

Fig. 5A and 5B are views for explaining an editing process of deleting a part (a plurality of building materials 31) of the building material set 3 in the building material arrangement fig. 3A by building material unit according to a designation from the outside. The designation method can be performed by dragging in a line while maintaining the designated state from the initial designated position. In this case, the plurality of building materials 31 existing in the linear designated range 182a from the first designated position to the last designated position can be designated. The designated range 182a may be either linear or curved. In addition, the designation range 182a is preferably highlighted.

When the first designated position and the last designated position are dragged so as to match each other and thereby form the designated area 182b having a shape of an area (circular, polygonal, or the like) inside, it is possible to designate a plurality of building materials 31 existing in the area surrounded by the designated area 182b and the designated area 182 b. After the plurality of specified building materials 31 are highlighted, all the specified building materials 31 are deleted at the specified positions, or are moved at once and are completely deleted by the trash icon 181, or are temporarily retained or changed in angle.

Further, as shown in fig. 5C, instead of specifying the building material 31, the construction area 21 may be specified as a target for scaling, and dragged in the left-right direction, the up-down direction, and the diagonal direction, so that the building material 31 may be added and deleted in conformity with the construction area 21 after dragging, thereby enabling the building material set 3 to be rearranged. In this case, when a plurality of construction areas 21 overlap, the construction area 21 to be scaled is scaled to rearrange the building material set 3, and the building material sets 3 in the remaining construction areas 21 are also rearranged.

Fig. 6 is a diagram for explaining an editing process for changing the designated building material 31 to another type. Specifically, for example, a plurality of building materials 31 are specified by the oval specification range 182b, and the category list 183 is displayed on the screen by operating a category change button, not shown. Then, by clicking (pressing) the display field of the part name (P tile, etc.) to be changed in the kind list 183, the plurality of specified building materials 31 can be changed to the kind to be changed at once. In the category list 183, when the number of categories of components is larger than the number of displays in the display field, the components can be scrolled in the vertical direction. In addition, the type can be changed after the temporary reservation or the angle change is performed.

Fig. 7 is a diagram for explaining an editing process of adding the building material 31 to the position designated from the outside in the building material arrangement fig. 3A. Specifically, the addition method is to perform addition by pressing an additional button, not shown, at a designated position, and to add a plurality of building materials 31 at a time by operating the additional button after forming a linear designated range 182a or a circular designated range 182 b. As shown in fig. 8, the addition button is operated to display the category list 183 on the screen, and the component name is designated and dragged out of the category list 183 to add the designated category of building material 31. The added building material 31 can be changed in angle, moved, or changed.

The added number of building materials 31 is added to the total number of building materials 31 constituting the building material layout fig. 3A, and the total number of added building materials 31 is displayed on the screen. The added number of building materials 31 may be displayed on the screen together with the total number of the added building materials 31. The screen display is preferably displayed in a manual input field indicating that addition is performed by "manual input". In this case, it is possible to easily check the data consisting of the total number of building materials 31 and the number of additions after the inspection.

Fig. 9 is a diagram illustrating an editing process for relatively moving the construction material arrangement fig. 3A displayed on the display device 18 and the construction area 21 of fig. 2 according to an operation from the outside. The relative movement is a movement in a predetermined size unit (a pixel unit of an image of the display device 18, or the like) in the vertical, horizontal, or arbitrary direction. In this case, the editing operation can be easily performed by relatively moving the building material layout fig. 3A displayed on the display device 18 and the construction area 21 of fig. 2 by an external operation.

Specifically, the designated range 182c is formed so as to surround the base material fig. 2 and the building material layout fig. 3A. Then, the designated base pattern 2 or building material arrangement pattern 3A is moved by designating the base pattern 2 or building material arrangement pattern 3A and dragging. In addition, the specified angle of the base view 2 or building material arrangement view 3A can be changed. In addition, in the case where the building material arrangement diagram 3A is specified by the specification range 182c, the kinds of all the building materials 31 can be changed.

Here, when the angle is changed, as shown in fig. 10, it is preferable that the angle change screen 184 is displayed in a superimposed manner, and the angle change screen 184 has a plurality of angle change lines 184a at 30 degrees/45 degrees or the like with respect to the horizontal line. The angle change line 184a can be automatically changed to an angle corresponding to the angle change line 184a in the building material arrangement diagram of fig. 3A by specifying the angle change line 184a to be changed by pressing or the like. The angle change line 184a may be displayed in a superimposed manner when the angle is changed in building material units.

(avoidance assignment of building Material estimation System)

As shown in fig. 1A, 1F, and 1G, the building material estimation system 1 includes a avoidance specifying unit 20 that specifies an arrangement avoidance area 211 in which the building material 31 is not arranged from the outside within the construction area 21 in fig. 2, and the arrangement diagram generating unit 13 preferably generates the building material arrangement diagram 3A formed such that the building material group 3 covers the construction area 21 other than the arrangement avoidance area 211. In this case, the posts, the atrium, and the like in the construction area 21 are set as the arrangement avoidance areas 211, so that the arrangement of the building material 31 to the posts, the atrium, and the like can be automatically avoided, and thus the editing work can be easily performed. The details of the operation of the avoidance specifying unit 20 will be described with reference to the ground surface generation processing in fig. 23 to 28.

In order to explain an example of the principle of the avoidance method of disposing the avoidance region 211 by using the building material 3 in fig. 11, the memory region corresponding to the building material disposition fig. 3A is divided into a plurality of image layer regions (the 1 st image layer 501, the 2 nd image layer 502, the 3 rd image layer 503, and the like). For example, the set of images for avoidance targets or the set of images for non-avoidance targets is divided into a plurality of image layers such as the 1 st image layer 501 and the 2 nd layer 502. For example, in the 1 st image layer 501, an arbitrary display position in the display device 18 is indicated by Ax and y in pixel units, and the display information Ax and y (0) can be set in the region to be avoided, and the display information Ax and y (1) can be set in the region not to be avoided. In addition, display information can be set in the avoidance region and the non-avoidance region in the same manner in other image layers such as the 2 nd image layer 502 and the 3 rd image layer 503.

Next, in the 1 st image layer 501, the display information Ax, y (1) is set in the non-avoidance region such as the ground, and the display information Ax, y (0) is set as the avoidance region in the other region. In the 2 nd image layer 502, the display information Ax, y (0) is set in the avoidance region such as the pillar, and the display information Ax, y (1) is set as the non-avoidance region in the other region. Then, the 1 st image layer 501 and the 2 nd image layer 502 are combined, and a logical product is obtained from the display information of the two

layers

501 and 502, thereby forming a combined image 511 having display information ABx and y (1) formed by removing avoidance areas such as pillars of the 2 nd image layer 502 from non-avoidance areas such as the floor of the 1 st image layer 501. The composite image 511 is output to the video memory and thereby displayed on the display device 18. Further, a construction area 21 is formed by the boundary line between the display information ABx, y (1) and the display information ABx, y (0).

The display positions Ax and y of the 1 st image layer 501 and the like are set in units of pixels, which are display units of the display device 18. Thus, when a size range is designated in the composite image displayed on the display device 18 and an actual size corresponding to the size range is input, actual sizes of the base map 2, the building material layout map 3A, and the like displayed on the screen can be obtained from the relationship between the number of pixels M existing in the size range and the actual size M of the size range. The display unit for obtaining the actual size may be a unit other than a pixel.

With the above configuration, as shown in fig. 1A, 1F, and 1G, a building material estimation device (building material estimation system 1) capable of determining the number of building materials 31 arranged in the construction area 21 of the building can be obtained. Specifically, the building material estimation device includes a memory 55 and a controller, and the memory 55 stores various data including data relating to the number of building materials 31. The controller performs the following processing: a base map acquisition process (base map acquisition unit 12) for acquiring a base map and storing the base map in the memory 55; a construction area setting process (construction area setting portion 53) of setting the construction area 21 in which the construction material 31 is to be arranged on the basic figure 2 stored in the memory 55 by the operation of the external device 19; avoidance specifying processing (avoidance specifying unit 20) for specifying the arrangement avoidance region 211 where the building material 31 is not arranged in fig. 2 stored in the memory 55 by operating an external device; a construction region changing process (construction region changing unit) of setting, in the memory 55, a 1 st layer in which the construction region 21 is a true value (1) and the regions other than the construction region 21 are stored as false values (0), and a 2 nd layer in which the layout avoidance region 211 is a false value (0) and the regions other than the layout avoidance region 211 are stored as true values (1), and calculating a logical product of the 1 st layer and the 2 nd layer, thereby setting a region where the construction region 21 and the layout avoidance region 211 overlap as the layout avoidance region 211; a layout generating process (a layout generating unit 13) of developing the building material set 3 in which the building material 31 is laid out in the memory 55 and generating a building material layout formed so that the building material set 3 covers the construction area 21; a display control process (display control unit 14) of controlling the display device 18 so that the building material layout drawing, the construction area 21, and the layout avoidance area 211 are displayed in an overlapping manner; a counting process (counting unit 16) of obtaining the number of the building materials 31 constituting the building material group 3 in the building material layout drawing from the building material group 3 developed in the memory 55 and the construction area 21; the output process (output unit 17) outputs the number of the building materials 31 to the outside.

In an actual building, there are areas where the building material 31 is not arranged, such as windows, pillars, doors, and the like. In this case, when the construction area 21 is set by the conventional method and system, if a column or the like arranged at a corner portion or a wall center portion of a room is present on a boundary line of the construction area 21, a process for avoiding the column or the like is required, and therefore, there is a problem that time and effort are required for setting the construction area 21. However, according to the above configuration, the construction region 21 can be easily set because the region where the construction region 21 overlaps with the layout avoidance region 211 is made the layout avoidance region 211 by performing logical product calculation on the 1 st layer in which the construction region 21 is a true value (1) and the regions other than the construction region 21 are stored as false values (0) and the 2 nd layer in which the layout avoidance region 211 is a false value (0) and the regions other than the layout avoidance region 211 are stored as true values (1).

(development display of building Material estimation System)

Further, the building material estimation system 1 preferably has a visualization function that can be visualized as an expanded view by clicking 3 points on a portion that cannot be visually recognized or confirmed in a plan view, such as a wall surface, in which openings such as complicated classification and attachment, window surfaces, and the like are arranged.

Specifically, as shown in fig. 1A, the building material estimation system 1 includes: a base map acquisition unit 12 for acquiring a base map 2, the base map 2 including a ground construction area and a wall construction area in which a building material 31 is to be arranged; a layout generating section 13 for generating a floor building material layout (building material layout 3A) formed so that a building material group 3 in which a plurality of building materials 31 are arranged covers a construction area 21, and generating a wall building material layout (building material layout 3A) formed so that the building material group 3 covers a wall construction area; a display control unit 14; an editing unit 15 that executes editing processing for deleting a part of the building material group 3 in the floor building material arrangement diagram and the wall building material arrangement diagram on a building material unit basis in accordance with a designation from the outside; a counting part 16 for respectively obtaining the number of the building materials 31 of the building material group 3 in the floor building material arrangement diagram and the wall building material arrangement diagram; the output unit 17 outputs the number of the building materials 31 to the outside.

As shown in fig. 12, the display control unit 14 can specify two

reference points

301 and 302 and one direction point 304 (solid line position/broken line position) on the wall surface from the outside, and control the display device 18 so as to display, as an expanded view, a wall surface construction area within a range on an area line 303 connecting the

reference points

301 and 302, including the direction point 304.

(development display of building Material estimation System: display method)

As shown in fig. 13A, when the polygonal pattern of the wall is drawn by folding the straight line, the viewpoint position is set on the right side with respect to the drawing direction (solid line/broken line) from the drawing start position P1 to the drawing end position P2, and an expanded view of the line of sight direction from the viewpoint position to the drawing direction is generated. When a four-sided pattern or a circular pattern of a room whose periphery is closed is drawn by a quadrangular or circular wall, an expanded view of a line of sight direction from the inside of the room to the outside is generated.

For example, fig. 13B shows a state in which a square room is formed by drawing in the arrow direction (clockwise drawing direction) from the drawing start position P1 and connecting the drawing end position P2 to the drawing start position P1 in the polygon mode. In this case, since the right side in the drawing direction arrow direction is the viewpoint position, the direction is set to be a line of sight direction from the inside of the room to the outside. When two reference points 301 and 302(X1 and X2) and one direction point 304(X3) on the wall surface are designated from the outside, a range on an area line 303 connecting the

reference points

301 and 302 including the direction point 304 is displayed as an expanded view of the visual line direction. In the case of a room, it is preferable that, when a right click is performed after one reference point 301(X1) on the wall surface is specified, an expanded view of the entire room is displayed.

For example, fig. 13C and 13D show a state in which a drawing is performed in the arrow direction (counterclockwise drawing direction) from the drawing start position P1 in the polygon mode, and a drawing end position P2 is connected to the drawing start position P1 to form a rectangular room. In this case, since the right side in the drawing direction is the viewpoint position, the viewing direction from the outside to the inside of the room is set. When two reference points 301 and 302(X1 and X2) and one direction point 304(X3) on the wall surface are designated from the outside, a range on an area line 303 connecting the

reference points

301 and 302 including the direction point 304 is displayed as an expanded view of the visual line direction.

For example, fig. 13E shows a state in which drawing is performed in the arrow direction (counterclockwise drawing direction) from the drawing start position P1 in the polygon mode, and the drawing end position P2 is separated from the drawing start position P1 to form a コ -shaped wall. In this case, since the right side in the drawing direction is the viewpoint position, the viewing direction from the outside to the inside of the wall is set. When two reference points 301 and 302(X1 and X2) on the wall surface are designated from the outside, the range on the area line 303 connecting the

reference points

301 and 302 is displayed as an expanded view in the visual line direction even if the direction point 304(X3) is not designated.

(herringbone counting method of building material estimation System)

A method of counting the building materials 31 in the case where the building material set 3 is arranged in a herringbone shape will be described in detail.

As shown in fig. 14, in the chevron counting process, an input process is performed (S51). Specifically, room coordinate information of the construction area 21, which is the tile width and the tile length of the building material 31, and room frame coordinate information of the non-distribution area 24 are input.

Next, calculation processing is performed. Specifically, first, the candidate calculation process is executed (S51). To explain the candidate calculation processing, as shown in fig. 16A, a determination area 521 of a quadrangle in which the room coordinates are completely contained is calculated. The determination region 521 has a horizontal (X-direction) width W and a vertical (Y-direction) length H. As shown in fig. 16B, when the size of the tile 311 is the horizontal width w (mm), the vertical length h (mm), and the joint width m (mm), the position of the center point of the tile 311 arranged in the herringbone shape is determined in the determination area 521. That is, when w > h, Δ w in the lateral direction and Δ h in the vertical direction from the start point of the determination region 521 are obtained by (equation 1) and (equation 2). Then, the center points C1 · C2 · C3 … are found as setting point candidates based on the positional relationship shown in fig. 16B.

Δ w ═ h + m × (2 ·) (formula 1)

Δ h ═ h/2+ m × √ 2 · (formula 2)

When all the setting site candidates in the determination area 521 are calculated, the tiles 311 are set as the setting site candidates (S53). The necessity determination process is performed on the set tile 311 (S54). Specifically, as shown in fig. 15, it is determined whether or not there is an overlap in the construction area 21 (S541). If there is NO overlap (S51: NO), the don't care flag is set (S544). On the other hand, when there is an overlap in the construction area 21 (YES in S51), next, it is determined whether or not there is a complete overlap with the non-allocation area 24 (S542). If the overlap is complete (YES in S542), an unnecessary flag is set (S544). If the overlap is not complete (S542: NO), a necessary flag is set (S543).

Next, it is determined whether or not the tile 311 is necessary based on the flag information in the determination process as necessary (S55). If necessary (YES at S55), after the count value is incremented (S56), it is determined whether or not the determination of whether or not all of the setting point candidates need to be tiles 311 is completed (S57). If the determination is not completed (S57: NO), the process is executed again from S53, and when the determination as to whether or not the tiles 311 are necessary for all the setting point candidates is completed (S57: YES), the output process is executed, and the count value is output as the necessary number of tiles 311 (S58).

As described above, in the case where the building materials 31 are arranged in the herringbone shape, the counting section 16 of the present embodiment can determine the number of the building materials 31 arranged in the construction area 21 by performing the following processing: a process of finding a square judgment area 521 surrounding the construction area 21 and expanding the area in the memory; a process of determining the position of the center point of all the building materials 31 in the determination area 521 when the building material groups 3 in which the building materials 31 are arranged in the herringbone shape are superimposed on the determination area 521, and setting the position as a candidate of the installation point; the process of determining whether or not the building materials 31 disposed as candidates for the installation site overlap each other in the construction area 21 and determining the number of the overlapping building materials 31.

In other words, the herringbone construction material estimation device (construction material estimation system 1) includes the counter 16, and the counter 16 obtains the determination area 521 of a regular quadrangle in which the construction area 21 is completely accommodated, obtains the position of the center point of the construction materials 31 arranged in the herringbone shape in the determination area 521 as the installation point candidates, develops the construction materials 31 in the memory 555 for all the installation point candidates in the determination area 521, and obtains the number of the construction materials 31 overlapped in the construction area 21.

Thus, conventionally, there has been no structure in which the building materials 31 are arranged in a herringbone pattern, and therefore the number of the building materials 31 arranged in a herringbone pattern cannot be obtained.

The counting unit 16 determines whether or not each of the building materials 31 disposed in the installation site candidates completely overlaps in the non-distribution area 24, and performs a process of subtracting the number of the overlapped building materials 31 from the number of the building materials 31 disposed in the construction area 21, thereby determining the number of the building materials 31 even when the non-distribution area 24 exists in the construction area 21.

In other words, as shown in fig. 1G, the herringbone construction material estimation device (construction material estimation system 1) includes a counter 16, and the counter 16 determines the number of construction materials 31 to be constructed and the number of avoidance of construction materials 31 to be completely included in the arrangement avoidance area 211, the number of construction materials 31 being at least partially overlapped in the construction area 21, from the construction material group 3, the construction area 21, and the arrangement avoidance area 211 developed in the memory 55, and subtracts the number of avoidance from the number of construction to determine the number of construction materials 31. According to the above configuration, the number of the building materials 31 can be accurately determined by subtracting the avoidance number from the number of works.

(building material estimation System: drawing function)

As shown in fig. 17A, the building material estimation system 1 preferably has a drawing function capable of drawing by manual work such as a mouse operation or a touch operation of a touch panel. The drawing function can add a drawing design in a blank screen. This enables, for example, a measurement to be performed in a hall at the site and a drawing to be performed.

As shown in fig. 17B, the building material estimation system 1 preferably has a magnifying glass function for magnifying and displaying an input area including an input portion for manual work. The input area is determined so that the input portion is at the center of the screen, in accordance with a preset magnification and the screen size of the enlarged display screen 41A. Thus, for example, when drawing is performed by the line drawing 411, when the end portions 411A and 411b of the line drawing 411 are close to each other, the end portions 411A and 411b can be easily connected to each other by drawing while visually observing the enlarged display screen 41A. Further, the magnifier function can also be switched by the operation of the ON/OFF button in the "scale" associated with "floor creation".

Further, the magnifier function can be automatically executed when executing the drawing function, and the execution state and the stop state can also be switched by a switching operation. In addition, in the state where the magnifier function is executed, it is preferable that the magnifier condition can be set. For example, in the execution state of the magnifier function, the magnified display screen 41A may be displayed only when the condition that the end portions 411A, 411b of the magnified display screen 41A are present within the magnified area is satisfied. In addition, the magnifying glass function may also be performed at a time other than when the charting function is performed. In this case, when the specification and the number value of the building material 31 are input, the input portion is displayed in an enlarged manner, and thus, the operation when using an information processing device such as a portable terminal having a small screen size is facilitated.

The building material estimation system 1, the building material estimation method, the management server 22, and the building material estimation program described above are not limited to the above, and can perform editing processing such as addition/deletion, change, and movement on the building material 31 in a unit for a part or all of the building material groups 3. That is, the building material estimation system 1, the building material estimation method, the management server 22, and the building material estimation program may be configured to set a plurality of construction areas 21 in which the building materials 31 are to be arranged on the base map 2, specify one or more construction areas 21, and select the building materials 31 used in the specified construction areas 21, instead of or in addition to the editing process.

Specifically, as shown in fig. 1A, the building material estimation system 1 includes: a basic diagram acquisition unit 12 for acquiring a basic diagram 2; a construction area setting portion 53 that sets a plurality of construction areas 21 in which the building material 31 is to be arranged on the base fig. 2; a building material specifying unit 54 for selecting one or more construction areas 21 and specifying the building material 31 used in the selected construction area 21; a layout drawing generation unit 13 that generates a building material layout drawing 3A for the entire construction area 21 selected by the building material specification unit 54, the building material layout drawing 3A being formed such that the construction area 21 is covered by the building material group 3 in which the building material 31 specified by the building material specification unit 54 is arranged; a display control unit 14 for controlling a display device 18 for displaying the building material layout drawing 3A so as to overlap the construction area 21; a counting unit 16 for obtaining the number of the building materials 31 constituting the building material group 3 in the building material layout diagram 3A generated in all the construction areas 21 selected by the building material specifying unit 54; and an output unit 17 for outputting the number of the building materials 31 to the outside.

In addition, the building material estimation method includes: a basic diagram obtaining step of obtaining a basic diagram 2; a construction area setting step of setting a plurality of construction areas 21 in which the building material 31 is to be arranged on the base fig. 2; a building material specifying step of selecting one or more construction areas 21 and specifying a building material 31 used in the selected construction area 21; a layout generating step of generating a building material layout diagram 3A for all the construction areas 21 selected in the building material designating step, the building material layout diagram 3A being formed such that the construction area 21 is covered by the building material group 3 in which the building material 31 designated in the building material designating step is arranged; a display control step of controlling a display device 18, the display device 18 displaying the building material layout fig. 3A so as to overlap the construction area 21; a counting step of obtaining the number of the building materials 31 constituting the building material group 3 in the building material arrangement diagram 3A generated in all the construction areas 21 selected in the building material specifying step; and an output step of outputting the number of the building materials 31 to the outside.

As shown in fig. 3, the management server 22 includes a base storage device 221 storing the base of fig. 2, a communication device 222 accessing the external terminals 23A to 23D, and a controller 223, and the controller 223 executes the following processing: a base map acquisition process of acquiring a base map of base map 2 from base storage device 221; a construction area setting process of setting a plurality of construction areas 21 in which the building material 31 is arranged in the basic fig. 2; selecting one or more construction areas 21 and performing a specified building material specifying process for the building material 31 used in the selected construction area 21; a layout generating process of generating a building material layout fig. 3A for all the construction areas 21 selected by the building material specifying process, the building material layout fig. 3A being formed in such a manner that the construction area 21 is covered by the building material group 3 in which the plurality of building materials 31 specified by the building material specifying process are arranged; a display control process of controlling external terminals 23A to 23D, the external terminals 23A to 23D displaying the building material layout drawing 3A so as to overlap the construction area 21; a counting process of obtaining the number of the building materials 31 constituting the building material group 3 in a building material arrangement diagram 3A, in which the building material arrangement diagram 3A is generated for all the construction areas 21 selected by the building material specifying process; and an output process for outputting the number of the building materials 31 to the external terminals 23A to 23D.

As shown in fig. 2, the building material estimation program causes the computer to function as: a basic diagram acquiring unit for acquiring a basic diagram 2; a construction area setting portion that sets a plurality of construction areas 21 in which the building material 31 is arranged in the foundation fig. 2; a building material specifying unit that selects one or more construction areas 21 and specifies a building material 31 used in the selected construction area 21; a layout diagram generation unit that generates a building material layout diagram 3A for all the construction areas 21 selected by the building material specification unit, the building material layout diagram 3A being formed such that a building material group 3 in which a plurality of building materials 31 specified by the building material specification unit are arranged covers the construction areas 21; a display control unit that controls a display device 18, the display device 18 displaying the building material layout fig. 3A so as to overlap the construction area 21; a counting part for obtaining the number of the building materials 31 constituting the building material group 3 in a building material layout diagram 3A, wherein the building material layout diagram 3A is a diagram generated for all the construction areas 21 selected by the building material specifying part; and an output unit for outputting the number of the building materials 31 to the outside.

According to the construction material estimation system 1, the construction material estimation method, the management server 22, and the construction material estimation program, by selecting one or more construction areas 21 and designating the construction material 31 to be used in the selected construction area 21, the construction material layout diagram 3A is generated at a time after the selection of the construction area 21 and the designation of the construction material 31 are completed in advance, and therefore, as compared with the case where the construction material 31 is designated in each construction area 21 and the construction material layout diagram 3A is generated, reconfirmation is easy, and a designation error of the construction material in each construction area 21 can be reduced. In addition, according to the above configuration, by setting a plurality of regions where the building materials 31 are to be arranged in fig. 2 as the construction regions 21, the regions where no arrangement is to be made are excluded from the calculation target of the required number of building materials 31, and therefore the required number of building materials 31 can be obtained with high accuracy.

(concrete example of building Material estimation System)

Next, a structure of the building material estimation system 1 will be specifically described, and the building material estimation system 1 includes: a database unit 11 for storing a design drawing file including design drawing data of a building (house, building, etc.), a building material specification file (size, shape, material, product name, part number, price, etc.) including size data and shape data of the building material 31, and a pattern file including layout pattern data (lattice layout, width offset layout, herringbone layout) of the building material 31; a base map acquisition unit 12 for acquiring a base map 2 (all or part of the floor, wall, and ceiling surfaces) including a construction area 21 in which the building material 31 is to be arranged, based on the design map data of the database unit 11; a building material specification file for specifying the size data and the shape data in the building material specification file and the arrangement mode in the mode file from the outside; a layout drawing generation unit 13 for generating a building material layout drawing 3A based on the size data, shape data, and layout pattern data specified by the building material specification unit, the building material layout drawing 3A being formed such that the building material group 3 in which the building material 31 is laid covers the construction area 21; a display control unit 14 that controls a display device 18, the display device 18 displaying the building material layout fig. 3A so as to overlap the construction area 21 of the basic fig. 2; an editing unit 15 that executes an editing process of deleting a part of the building material group 3 in the building material arrangement diagram 3A in building material units according to a designation from the outside and an editing process of adding the building material 31 to a position designated from the outside in the building material arrangement diagram 3A; a counting part 16 for obtaining the number of the building materials 31 constituting the building material set 3 in the building material layout diagram 3A; the output unit 17 outputs the number of the building materials 31 to the outside.

(concrete example of building Material evaluation System: Label management)

As shown in fig. 18, the building material estimation system 1 is configured to be able to execute a large-scale process to a detailed-scale process by associating a predetermined process with a plurality of levels of tags and icons displayed on a screen. For example, the "drawing", "angle correction", "distortion correction", "clipping", and "scale" are present as the 2 nd floor associated with the "floor creation" of the 1 st floor. Further, as the 2 nd floor associated with the "floor generation" of the 1 st floor, there are "floor selection", "house frame setting", "room generation", "room editing", "staff", and "memo". Further, as the 3 rd layer associated with the "room editing" of the 2 nd layer, there are "wall height change", "area generation", "subtraction addition", "assignment start", "assignment editing", "free input", and "editing determination". In "area generation" at layer 3, "room isomorphism" and "area copy" are associated therewith as layer 4. Note that the layer structure of fig. 18 is an example, and labels and icons corresponding to various functions not shown are also present.

Specifically, the label on the layer 1 corresponds to the process of project information, floor creation, wall creation, ceiling creation, space creation, part master data, opening master data, part count, and certificate output. Here, the component master data tag corresponds to the database unit 11, and can read various information of the building material 31. The opening master data tag can read various information of the layout avoidance area such as a window and a door in accordance with the processing of the avoidance specifying unit 20. The part number calculation tag corresponds to the counting section 16. The voucher output label can output the amount of money to be paid in accordance with the unit price of the building material 31 and the number of the building materials 31, in addition to the function of the output unit 17. The other labels will be described later.

(concrete example of building Material estimation System: project information processing)

Fig. 19 shows an initial screen 601 displayed when the information processing apparatus is started up, and a tab selection area 6011 for the layer 1 is disposed above the initial screen 601, and a processing area 6012 is disposed below the tab selection area 6011. The item information processing is executed at the time of startup of the information processing apparatus, and a registration area 6102a is displayed in the processing area 6012. Basic information (customer name, project name, etc.) can be input in the registration area 6102 a. In addition, five items, that is, "customer name", "construction side", "project name", "person in charge", and construction day ", are displayed by default, but arbitrary items can be freely added.

(concrete example of building Material estimation System: floor creation processing)

Fig. 20 is a display screen when the floor creation tab is operated. In general, when item information is input, a transition is made to a floor creation tab, and a desired drawing can be read from a drawing reading window 6013 for displaying a list of a plurality of drawings 6014. After the reading of the map is completed, as shown in fig. 21, a map 6014 is displayed substantially in the center of the processing area 6012. In addition, when correcting an angular deviation or distortion with respect to the drawing 6014, correction can be performed by operating the angle correction icon or the distortion correction icon.

In addition, only a desired portion of the drawing 6014 can be cut (see fig. 2). The cutting method can perform cutting by clicking a cutting icon and surrounding the portion by a mouse operation. For example, the region can be surrounded by clicking the top left vertex of the region and operating the mouse down and right. In the following description, various designation and operation performed on the display screen will be described using the expression of the mouse operation, but the touch operation may be performed using a touch panel.

As shown in fig. 22, when the scale icon is clicked, scale processing for calculating the actual size of each part of map surface 6014 is executed. For example, when two positions which are the longest rotation ends of the scale range 6015 on the drawing surface 6014 to be the scale reference are clicked and the scale input screen 6016 is skipped, the actual sizes of the clicked scale ranges, that is, "10" and "714" are input. Thus, the actual size of each position in the drawing 6014 is calculated from the relationship between the actual size of the scale range 6015 and the number of pixels present in the scale range 6015.

As shown in fig. 23, when the ground generation tag is operated, the ground generation processing is executed. For example, when a floor selection icon is clicked from a floor generation tag, and a drawing with a scale set is called and displayed on the screen, the drawing is displayed at the center of the screen. Then, as shown in fig. 24, when house frame setting processing for setting a house frame position (post/atrium) is performed, the post generation and atrium generation can be selected by selecting a house frame setting icon. When a column is selected, a column generation icon is selected, and a four-side icon 6301, a circle icon 6302, and a polygon icon 6303 are displayed. Then, any one of the

shape icons

6310, 6302, and 6303 is selected, and a mouse operation is performed so as to surround the image of the bar displayed on the screen. In fig. 24, a four-side mode is performed by selecting the four-side icon 6301, and the bar is enclosed by the four-side mode. Further, the pillar 6017 located at the end of the room can be surrounded in a slightly protruding manner.

As shown in fig. 25, after the processing of "column generation"/"atrium generation" is finished, the common wall height icon is clicked to input the wall height. That is, if the common wall height icon is clicked, the wall height input window 6018 appears. Then, the common wall height is input to the input field in the wall height input window 6018, and the edit determination icon is clicked, whereby the house skeleton setting process is ended.

As shown in fig. 26, when the room generation icon is operated, room generation processing for selecting a room is executed. Specifically, the room creation display 6102 is caused to appear by selecting a room creation icon from among the icons displayed on the floor top menu display 6101. When any one of the four-sided icon 6102a, the circular icon 6102b, and the polygonal icon 6102c in the room creation display 6102 is selected, the room can be created by the drawing mode processing corresponding to the selected icon 6102a, 6102b, or 6102 c. Further, the default drawing mode processing is multilateral drawing.

Then, for example, when room generation is performed in the polygon mode, the drawing mode processing by the polygon icon 6102c is selected, and a red reinforcing line is drawn along the drawing surface by a mouse operation. The point where the reinforcing line is bent is clicked, and the room is drawn so as to be surrounded by the reinforcing line. Further, the part of the house frame is drawn along the house frame. When the reinforcing line reaches a position close to the starting point, a right-click is performed, and an auxiliary window 6019 "continuous with the starting point" appears. When "connect to start point" is selected, the start point and end point of the reinforcement line automatically match, the room is surrounded by the reinforcement line, and the area, perimeter, and wall area of the entire room surrounded by the reinforcement line are displayed in the display column at the lower left of the screen. In addition, when a house frame such as a freestanding column is present in a room, the perimeter of the house frame is added to the perimeter of the entire room surrounded by the reinforcing wire, and the installation area of the house frame is subtracted from the floor area of the entire room. In addition, when an atrium exists in a room, the installation area of the atrium is subtracted from the floor area, and the perimeter is maintained without affecting the perimeter of the entire room.

As shown in fig. 27, when the room editing icon is operated, room editing processing is executed in which a "region" (construction region 21) is set for the entire room. Specifically, the room edit icon is clicked, and the room edit display portion 6103 is displayed. Then, the area creation icon displayed on the room editing display 6103 is clicked, and the area creation display 6104 is displayed. The area generation display 6104 includes room isomorphism icons and area drawing icons, and can generate the icons by performing drawing mode processing of the selected icons.

In the case where the "area" in the same shape as the room is selected, the room isomorphic icon is selected, and in the case where the "area" in a different shape from the room is selected, the area drawing icon is selected. When the area drawing icon is selected, the escape area drawing display 6105 can select drawing processing corresponding to any of the four-sided icon, the circle icon, and the polygon icon. For example, when the drawing mode processing of the four-side icon is selected, the upper left vertex of the target "area" is clicked, and the mouse is operated in the lower right direction. Furthermore, the top left vertex may also be located outside of the "zone". The quadrangle of red is enlarged by the mouse operation, and when the "area" is surrounded by the red line of the quadrangle, the "area" is determined to end the processing. At this time, as shown in fig. 28, if a portion such as a column where the building material 31 is not required to be distributed is designated as the arrangement avoiding region 211, the red line of the quadrangle is drawn avoiding the portion.

As shown in fig. 29, when the distribution start icon is operated, the distribution process of distributing the floor material to the range where the "area" generation is performed. Specifically, when the assignment start icon is clicked, the display window 6020 of the registered component master appears. For example, if a tile of 250 × 1, 000 is selected and the OK button is clicked, the assignment method selection window 6021 is skipped next. The dispensing method selection window 6021 is shown to enable selection of a dispensing method composed of "normal", "seam (width misalignment)", "seam (height misalignment)", and "herringbone", and to jump out of the dispensing angle selection window 6022 after selection of a certain dispensing method.

For example, if "seam crossing" is selected in the distribution method selection window 6021, and "90 degrees rotation" is input in the distribution angle selection window 6022, and then the provisional distribution button is clicked, as shown in fig. 30, a grid 6023 (building material group 3) corresponding to the present distribution is displayed. Further, a cross key window 6024 appears in the vicinity of the mesh 6023, and the mesh 6023 can be moved in the vertical direction and the horizontal direction by clicking the cross key, whereby the overhanging position can be moved.

If the position determination button is clicked, the total number (100) of carpet tiles 6023a at the overhanging position at the time of the click is displayed as shown in fig. 31. In addition, as shown in FIG. 32, for an unwanted carpet tile 6023a, by clicking on the carpet tile 6023a, it is deleted from the grid 6023 and subtracted from the total number. In fig. 33, when the carpet tiles arranged at three positions are clicked, the carpet tiles at the clicked positions are deleted, and the total number of the carpet tiles (97 carpet tiles) obtained by subtracting 3 carpet tiles is displayed. After the operation of subtracting an arbitrary number of carpet tiles is finished, the allocation decision button is clicked, and the information on the number of carpet tiles allocated is added to the allocation information display unit disposed in the lower part of the screen. In addition, by double-clicking the "number" of display areas in the allocation information display unit, an arbitrary number of display areas can be added.

As shown in fig. 34, when the free input icon is operated in the room editing, the free input process is executed. For example, when five pieces of 250 × 1, 000 floor materials of different colors are required, the free entry icon is clicked, the display window 6020 of the registered part master appears, and the part is selected. After this component is selected, the number of input screen windows 6025 are displayed, and therefore, a necessary number is input and the OK button is clicked. Thereby, the input data is added to the assignment information display portion 6026.
