Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a rectangular drawing creating system capable of generating a detailed vertical sectional view (rectangular drawing) of a building using CAD data.

[0002]

2. Description of the Related Art A CAD system is used to create a floor plan, an elevation, a floor plan, etc. necessary for building a house. On the other hand, at a construction site, a detailed vertical sectional view of a building is required in addition to a plan view and an elevation view. This drawing is called a quadrangle drawing and is also used when applying for confirmation based on architectural regulations.

[0003] In the quadrangle drawing, detailed arrangements and dimensions of parts over the details of the building are entered. In contrast, CA
Only the main parts of the building are entered in the floor plan, elevation and the like created by the D system. That is, the CAD system does not have information such as the arrangement and dimensions of the detailed components over the details of the building. Therefore, the drawing creator selects the parts necessary for creating the quadrangle drawing while referring to the design drawing separately from the CAD system, collects and combines the image data of these parts, and traverses the building longitudinally. A plan view is generated (Japanese Patent Application Laid-Open No. 8-167046). Such a drawing process also uses a CAD application program, but is a process separate from a CAD system for building design.

[0004]

However, the above-mentioned prior art has the following problems to be solved. As described above, the operation of accurately selecting the parts necessary for creating the quadrangle drawing requires skill. Also, prepare the image data of many parts necessary for creating the quadrangle drawing in advance,
The process of collecting, arranging, and compositing the selected items to generate a longitudinal sectional view of the building requires a lot of trouble and time. Further, there is a problem that management for individually preparing and storing the image data of these many components is complicated, and a large-capacity storage device is required.

[0005]

The present invention employs the following structure to solve the above problems. <Configuration 1> A CAD system for executing a basic design of a building, and a quadrangle drawing generator for generating a vertical cross section of the building are provided. A storage device that stores an image data group that is an image that displays a unique unit, and that collects image data that has been given a file name in accordance with a preset characteristic parameter;
A data selection processing unit that acquires characteristic parameters of main parts included in the vertical sectional view of the building from the CAD system, and selects and reads out image data of a unit including the relevant main parts from the storage device. A rectangular meter drawing creation system characterized in that:

<Structure 2> In the quadrangle drawing creating system described in Structure 1, a component arrangement processing unit for arranging the read image data of the unit on a reference line based on predetermined position information is provided. Characteristic rectangular meter drawing creation system.

<Structure 3> An image displaying a unit required for generating a vertical sectional view of a building, which is an image data group obtained by collecting image data to which a file name is given according to a preset characteristic parameter, is stored in a storage device. From the CAD system that executes the storing process and the basic design of the building, the characteristic parameters of the main parts included in the longitudinal sectional view of the building are obtained, and the image data of the unit including the relevant main parts is obtained from the storage device. A computer-readable recording medium in which a computer program for executing a process of selecting and reading and arranging on a reference line based on predetermined position information is recorded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below using specific examples. FIG. 1 is a block diagram of a system for creating a rectangular drawing according to the present invention. The illustrated system comprises a CAD system 10 and a rectangular drawing creating unit 1 connected thereto. The CAD system 10 and the rectangular drawing creating unit 1 are each realized by, for example, a personal computer or a workstation (not shown), and each includes a processor and a storage device. Also, in this figure, only functional blocks necessary for explanation are displayed to avoid complication.

The CAD system 10 stores drawing data such as a plan 11, an elevation 12, and a floor plan 13 for designing a building. All of these data are CA
It is created by a drawing creation application program (not shown) that operates on the D system 10. The rectangular drawing creation unit 1 includes a data selection processing unit 20, a storage device 30, and a component arrangement processing unit 40. The data selection processing unit 20 receives data 21 of a main part for creating a rectangular drawing from the CAD system 10,
It has a function of acquiring the characteristic parameter 22 of the main part from this, and generating a file name 23 based on the characteristic parameter 22.

The main part data 21 is data necessary for obtaining the characteristic parameters 22 included in the drawing data, and is, for example, character data such as a part list. The component list includes attribute data such as dimensions and types of the components. The characteristic parameter 22 is a component name and attribute data of a specific component in the component list.
As will be described later, the file name 23 is generated by, for example, connecting characteristic parameters.

The storage device 30 stores image data 31 of a unit including main components. The image data of a unit is different from the image data for individual parts of a CAD system that performs a basic design of a building. The image data of the unit is, for example, a detailed longitudinal sectional view of a roof portion specified by a predetermined characteristic parameter. It contains all necessary display and component image data. CA
Part data not included in the drawing data stored in the D system is also included. Further, since the image data is collected for a detailed vertical sectional view, the data size is sufficiently smaller than the case where the image data of each component is stored separately. Of course, the work of collecting and synthesizing the data of each part is unnecessary.

The component arrangement processing unit 40 is a unit for processing image data 4 selected from the image data 31 stored in the storage device 30.
1 and the position information 42, and has a function of generating a rectangular drawing 43. When the storage device 30 is accessed using the file name 23 obtained by the data selection processing unit 20, the image data 41 of a predetermined unit is selected. The position information 42 is information indicating a mutual positional relationship when the selected image data 41 is arranged and combined. The rectangular drawing 43 is data obtained as a result of aligning and combining the image data of the units. The rectangular drawing 43 is displayed on the display 51, and is printed by the printer 52 after completion.

In the above-described system, data of main parts included in a longitudinal sectional view of a building is received from the CAD system 10, and the characteristic parameters are acquired. For example, when creating a vertical sectional view of the roof part, the material of the roof, the slope, and the dimension under the eaves are extracted as feature parameters. Since the types of roofs of houses actually sold are limited, specifying some characteristic parameters makes it possible to specify all the components necessary for the vertical sectional view of the roof and their arrangement and dimensions. That is, the vertical sectional view of the roof part can be specified.

[0014] Image data of a longitudinal sectional view of a roof portion is prepared for only types corresponding to combinations of characteristic parameters that can appear. In the present invention, this image data is
This is called the image data of the unit including the main parts. The number of image data is sufficiently smaller than that of storing the image data of all the components included in the longitudinal sectional view individually, and the data management becomes easy. Of course, even if the image data of all necessary units is stored, the storage capacity may be smaller than in the conventional case.

The storage device 30 stores image data of all units having different characteristic parameters. CA
The characteristic parameters of the roof, ceiling, opening, wall, balcony, underfloor and foundation are obtained from the D system, and these units are selected and connected to complete the quadrangle drawing. Therefore, the operation of synthesizing the parts is greatly simplified as compared with the related art. Further, since the image data of the unit is automatically selected, the work of creating the quadrangle drawing is quick and reliable.

If a file name is given to each unit in accordance with a characteristic parameter that can specify each unit, the contents of each image data in the storage device 30 (FIG. 1) are
There is an effect that the file name makes it clear at a glance and management becomes easy. For example, in a house using a tiled roof, the gradient is 4. Assume that the dimension under the eaves is 70. These are the characteristic parameters of the roof. The image data file name of the unit of the roof portion having such a characteristic parameter is K4-70. The symbol for designating a tiled roof is K.

In order to generate a longitudinal sectional view, a roof portion, a ceiling portion, an opening portion, a wall portion, a balcony portion,
The image data of 4 to 5 units such as the underfloor and the base portion are combined. The image data of each unit is arranged at a predetermined position along a predetermined reference line. If information indicating the size of each unit, the position in the height direction, and the offset with respect to the reference line is obtained from the CAD system, the image data of the unit selected automatically can be arranged and synthesized. Note that the position information may be manually input. The above is a brief description of the present invention. Hereinafter, the system of the present invention will be described more specifically.

FIG. 2 is a longitudinal sectional view of a house showing a specific example of a rectangular drawing. The middle part of this figure is omitted. That is,
In this example, the units of the roof portion, the ceiling portion, the underfloor, and the foundation portion are mainly illustrated. As shown, the rectangular drawing includes longitudinal cross-sectional views of components such as roof 58, attic 59, ceiling 53, wall 54, and the like. Further, detailed vertical sectional views of the floor 55 and the foundation 56 are included under the floor and the foundation. The CAD system drawing does not include the detailed internal structure of the ceiling or the internal structure of the wall. However, if the type, material, dimensions and other conditions of the roof are determined, the structure under the eaves and the eaves are automatically determined.

FIG. 3 is a back explanatory view showing an example of image data 31 of a unit including the main parts shown in FIG. (A) of the figure shows image data in the case of a tiled roof, eaves eaves of 910, roof inclination of 5, and shed 30. The file name is shown below each image data. C5 if the same tiled roof and the slope is 5, if the eaves are 910-
9, F30 when the shed is 30 and F40 when the shed is 40. (A) is an example of 30 sheds, and (b) is an example of 40 sheds. In (c), F is K because the structure under the eaves is different.

These image data include all dimension lines and other various information to be displayed in the rectangular drawing. All information included in the file names of these image data can be extracted from the CAD system as feature parameters. As described above, in this embodiment, the characteristic parameters are directly linked to form a file name.
Therefore, the file storing the image data can be easily read from the storage unit by the characteristic parameter.

FIG. 4 is a view for explaining the contents of image data of a unit including main parts stored in the storage device 30 shown in FIG. (A) shows the classification and selection conditions of image data,
FIG. 3B shows an example of position information and the like necessary when a rectangular drawing is created using image data. As shown in (a) of the figure, the image data of each component is arranged in a classification such as a large classification, a middle classification, and a small classification. Major classifications are, for example, roofs, walls, and ceilings. The middle category is a category indicating roof materials such as tiles and slate. By such a classification, image data groups to be selected are narrowed down in advance from image data of many parts.

Further, specific image data is extracted using the selection conditions A, B, and C as shown in FIG. The selection conditions A and B
C is a feature parameter. In this example,
The combination of the middle classification / small classification and the characteristic parameters A, B, and C is directly assigned to the file name of the selected component. Therefore, for example, the characteristic parameters of a roof using a tile and a roof using tiles are A1, B1, and C.
In the case of 1, a file name is generated by connecting the selection condition to a classification symbol. If table data as shown in FIG. 4A is stored, the file name of the corresponding image data can be easily acquired using the characteristic parameter as a key. The management of the image data stored in the storage device 30 can also be performed using the table data. That is, if the image data is classified in this way, even if the specification or shape of the building is changed, it is possible to cope with the situation simply by maintaining the table data and adding the image data of the necessary unit. .

Further, as shown in FIG. 4B, each selected component includes the basic arrangement coordinates for positioning the unit as table-like attribute data.
The parametric dimension value is data for size adjustment when the units are arranged side by side and synthesized. The image data of the roof, the image data of the wall and floor, and the image data of the underfloor and the foundation are vertically aligned, aligned using the basic arrangement coordinates, and dimensioned using parametric dimension values. The rectangular drawing as shown is completed. It should be noted that the parametric dimension value may be manually changed as needed.

FIG. 5 is an explanatory diagram of the procedure of the rectangular drawing creation processing by the system of the present invention as described above. FIG.
1 is a system configuration diagram of the present invention. FIG. 5 illustrates a specific operation of each block shown in FIG.
Displayed to correspond to Rectangular drawing creation unit 1 of FIG.
Executes the rectangular drawing creation process in the procedure shown in FIG.
First, in step S1 of FIG. 5, the data selection processing unit 20 illustrated in FIG. 1 acquires data 21 of a main part from the CAD system 10. Specifically, as shown in FIG. 6, the computer on the side of the rectangular drawing creating unit 1 refers to the CAD data 61 stored in the storage device 60 of the computer on the side of the CAD system 10. And network 6
2 to obtain data 21 of the main parts.

In step S2, feature parameters 22 of the main part are extracted from the data. Then, in step S3, the table data shown in FIG. 6 is referred to using these characteristic parameters 22 as keys.
Thereby, the file name 23 is generated. Using the file name 23, the image data 31 stored in the storage device 30 shown in FIG. 6 is selected and read (step S4). In the next step S5, the selected image data 31 is called on the display screen of the display 51. And
To create a rectangular drawing, it is placed on a reference line 50 shown in the figure. At this time, the image data 41 is positioned at a predetermined position on the reference line 50 based on the position information described with reference to FIG.

This position information is stored in the table data 63 shown in FIG.
The specific contents are shown on the right side of FIG. The offset indicates the amount of displacement from the reference line 50 in the horizontal direction. Since the offset is 0, the center line of the image data 41 and the reference line 50 are matched. Since the width is 70 and the height is 45, the vertical and horizontal dimensions are adjusted to the dimensions. Thus, the image data 41 is displayed on the display after being adjusted to a predetermined size. The processing from step S2 to step S6 is repeated for the number of units. For example, in the example of FIG. 2, the unit on the roof, the unit on the floor at the boundary between the first and second floors, the unit on the lower floor of the first floor and the unit on the foundation are arranged in order, and the unit on the wall is overwritten. With such a procedure, a rectangular drawing is completed. This drawing is printed by the printer 64 shown in FIG.

According to the above method, the feature parameters of the main parts are automatically extracted from the CAD system,
Since the image data satisfying these characteristics can be automatically read out from the storage device and arranged, the operation of selecting the parts becomes very simple. Further, since the image data is not divided for each fine part, it is not necessary to manage the image data of many parts. Furthermore, since the number of image data to be actually arranged and superimposed is very small, it is easy to adjust the position and size at the time of superimposition, thereby also increasing the efficiency of creating a rectangular drawing. .

The function blocks such as the data selection processing section 20 and the component arrangement processing section 40 shown in the above-mentioned rectangular drawing creating section may be constituted by separate program modules, respectively, or may be constituted by integrated program modules. May be. Further, all or a part of these functional blocks may be configured by hardware using a logic circuit. Further, each program module may be operated by being incorporated into an existing application program, or may be operated as an independent program. These computer programs can be recorded on a computer-readable recording medium such as a CD-ROM, installed, and used.
