Description

  The present invention relates to a program for adjusting the position of a specific object in CAD data, and mainly relates to a program for adjusting a position already adjusted by a user on a corrected drawing.

As a background art, a layout apparatus for creating a layout diagram will be described. This layout apparatus is used, for example, when creating a layout drawing at a remodeling store. In a renovation store, when a customer who wants to remodel kitchens, toilets, baths, etc., consults with a remodeling shop clerk, the clerk listens to the customer's wishes while viewing the catalog. While hearing, the store clerk creates a layout diagram as requested by the customer using the layout device. The layout device is a device that creates a reform layout diagram by combining parts handled by a renovation shop. For example, in the case of a system kitchen, the components constitute a system kitchen such as a sink, a range hood, a dishwasher, floor storage, and wall storage. The store clerk points the display of the layout device to the customer and completes the layout by combining the desired parts on the layout device while viewing the catalog. A customer's remodeling environment can be input to this layout device, and a field survey is performed in advance. After completing the layout creation, the store clerk uses the layout device to automatically generate a design drawing from the layout drawing. Specifically, based on a layout diagram composed of symbol data of components, the corresponding components are read out from a storage means in which a large number of CAD-format component data of the components corresponding to the symbol data are recorded, and CAD data of the design drawing is automatically generated. In the CAD data, each part is grouped, and a part number and a part name with a circled number are given to each part in the process of automatic generation. Here, the part number and part name assigned to each part are also grouped together. The part number is used in the part column provided at the corner of the drawing. In the part column, detailed information of the part is described. For example, the part name, material, number, weight, process, and remarks are provided. When the automatically generated CAD data is read by the CAD device, a design drawing (construction drawing, product three-side view) is displayed on the display. In the design drawing displayed on the display, since the part number and the part name are automatically assigned to the part, the part number and the part name are often arranged on the line constituting the part. In this case, the store clerk performs the operation of moving the object, which is a basic function of the CAD device, and arranges the part number and the part name so as not to overlap the line. Then, submit a well-designed blueprint and estimate to the customer. The customer confirms the blueprint and estimate and makes a contract. When the contract is finalized, a blueprint is delivered from the remodeling store clerk to the contractor, and the contractor performs the construction according to the blueprint. The renovation is completed through the above series of flows.
Japanese Patent Laid-Open No. 9-6981 JP-A-8-202891

  The above patent document relates to a CAD (Computer Aided Design) apparatus. The former relates to an undo function for restoring back to an arbitrary operation and a redo function for canceling this undo. The latter relates to a function of saving a view selected by the user, and selecting and switching the display arbitrarily from the saved views. These patent documents are references in the same technical field as the present invention, and since their relevance is low, detailed description is omitted.

  According to the layout apparatus of the background art, a store clerk can create a layout diagram in collaboration with a customer, and a layout diagram according to the customer's intention can be created. However, customers often instruct shop assistants to look at the received blueprints. In accordance with this instruction, the store clerk performs part size adjustment, part replacement, part deletion, etc. on the layout device, and automatically generates a design drawing again. Although the automatically generated blueprints are arranged according to the instructions of the customer, the part number and part name arranged for each part are automatically arranged, so they are arranged on the line, The store clerk has a problem that it is necessary to arrange the part number and the part name performed on the design drawing automatically generated last time in the same manner.

  The present invention has been made to solve the above problems, and even when the design drawing is automatically generated again by changing the layout, the user himself / herself performed the design drawing that was automatically generated last time. It is an object of the present invention to provide a program that can be reflected on a design drawing that is automatically generated this time without performing an operation for correcting the position of a position adjustment primitive such as a part number and a part name.

This is to execute a large position adjustment procedure of the position adjustment primitives consisting of the steps to be performed. As described above, in the present invention, component identification information, position coordinates of primitives requiring position adjustment, component placement origins are obtained for each part in a large procedure for obtaining part information before drawing placement, new CAD data is generated, and position adjustment is performed. Primitive position adjustment Identifies a part that has the same part identification information as the part identification information obtained in the large procedure, finds the position coordinates of the identified part, and locates the origin of the part. Since the relative position of the position adjustment primitive is calculated from the position coordinates of the primitive and the part placement origin, the position adjustment primitive is adjusted for the difference, so the position adjustment primitive is moved with respect to the part that has already been adjusted by the user. Therefore, the position adjustment is automatically completed, and the labor of the user is greatly reduced. The primitive requiring position adjustment, which is a primitive that requires position adjustment, corresponds to a part number and a part name, for example. This automatic adjustment program corresponds to a CAD data generation program in an embodiment described later. The automatic adjustment program is named because the main part of the invention is automatic adjustment.

  (2) The automatic adjustment program according to the present invention provides a computer with a procedure for obtaining a drawing arrangement origin in CAD data before correction, and part identification information for identifying a part from group data of parts constituting the CAD data before correction. Pre-placement of drawing, consisting of a step of taking out, a step of taking out position coordinates and attributes of primitives that require position adjustment from primitive data constituting group data, and a step of obtaining a component placement origin A new drawing layout that reads out the corresponding CAD data format part data based on the component information acquisition procedure and the layout data consisting of the part symbol data, part placement coordinates and part identification information, and places the part based on the placement coordinates.

This is to execute a procedure for moving and a large position adjustment procedure for primitives for position adjustment including a procedure for updating the attributes of primitives for position adjustment of new drawings to the attributes of primitives for position adjustment of existing drawings. In addition to the automatic adjustment program of (1), the automatic adjustment program of (2) updates not only the position of the position adjustment primitive but also the attribute according to the existing figure, so that the user can add the previous existing figure to the previous figure. In addition to the position adjustment of the position adjustment primitive performed for the position update, the update of the attribute of the position adjustment primitive is automatically reflected in the new drawing, and the convenience for the user is further enhanced. The attributes of the position adjustment primitives include, for example, line type, line color, line length, font, font size, font color, and the like.

The part having the same part type identification information as the part identification information obtained in the large position adjustment procedure of the position adjustment primitive is identified, and the position coordinates of the position adjustment primitive of the identified part and the component origin of origin are obtained. Then, the position coordinates of the primitives requiring position adjustment, the position origin of the component and the position coordinates of the recorded primitives requiring position adjustment, and the relative position difference of the primitives requiring position adjustment from the part placement origin are obtained, and the position adjustment primitives corresponding to the difference are obtained. For parts that have been adjusted by the user or previously adjusted by other users Positioning a main primitive is not necessary to move the automatically positioning is completed, effort of the user is greatly reduced. Here, even for a plurality of users, since the position adjustment primitives are adjusted to the same position, it is possible to unify them and prevent them from being arranged at different positions depending on the users.

These outlines of the invention do not enumerate the features essential to the present invention, and a sub-combination of these features can also be an invention.

Here, the present invention can be implemented in many different forms. Therefore, it should not be interpreted only by the description of the following embodiments. In addition, the same reference numerals are given to the same elements throughout the embodiments.
In each embodiment, the apparatus will be mainly described. However, as is apparent to those skilled in the art, the present invention can also be implemented as a program, method, and system that can be used by a computer. In addition, the present invention can be implemented in hardware, software, or software and hardware embodiments. The program can be recorded on any computer-readable medium such as a hard disk, CD-ROM, DVD-ROM, optical storage device, or magnetic storage device. Furthermore, the program can be recorded on another computer via a network.

(First embodiment of the present invention)
A CAD data generation apparatus according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a hardware configuration diagram of a computer according to the present embodiment. The computer 10 is a general-purpose computer. The hardware configuration includes a CPU (Central Processing Unit) 11, a main memory such as a DRAM (Dynamic Random Access Memory) 12, and an HD (hard disk) 13 that is an external storage device. , A display 14 as a display device, a keyboard 15 and a mouse 16 as input devices, a LAN card 17 as an expansion card for connecting to a network, a CD-ROM drive 18 and the like.

  A layout program, a CAD data generation program, and a CAD program are recorded on the HD 13 of this computer. A program recorded in advance on a CD-ROM, which is a computer-readable medium, is read out via the CD-ROM drive 18 and copied and recorded in the HD 13 so-called installation is performed in advance.

  The layout program is configured by the layout program being read into the main memory 12 and executed by the CPU 11. The CAD data generation program is configured by reading the CAD data generation program into the main memory 12 and executing it by the CPU 11. A CAD program is configured by reading the CAD program into the main memory 12 and executing it by the CPU 11. In the present embodiment, a plurality of devices are configured by one computer, but a plurality of devices can also be configured by a plurality of computers.

  FIG. 2 is an example of a screen display of the layout apparatus according to the present embodiment. The layout device has a procedure for inputting the customer's construction environment, a procedure for presenting the part, a procedure for placing the part selected by the user at a position specified based on the inputted construction environment, and a part. A procedure of assigning component identification information and a procedure of drawing with a designated display are executed. The specified display is, for example, “whole display” “up scroll” “rectangular enlargement” “enlargement” “right scroll” “reduction” “redisplay” “down scroll” “previous screen” “left scroll” “standard display” There is. As shown in FIG. 2, a plan view of the layout is displayed on the upper stage, a front view of the layout is displayed on the lower stage, and an operation column is displayed on the right end side. The layout apparatus records the created layout as layout data with a specified name in a specified location on the HD 13. The layout data consists of part symbol data.

  The layout device gives part identification information to each part. However, when the layout diagram is modified, the same part identification information is retained for the parts that are not modified, and the parts that have been modified are new. The part identification information is given to.

  Symbol data and CAD data format component data are associated with each other and recorded on the HD 13. The CAD data generation device generates a group data including a procedure for reading the corresponding component data from the HD 13 based on the symbol data of the components constituting the layout data, and the component data obtained by reading the component arrangement position based on the arrangement position of the symbol data. A procedure of assigning and a procedure of assigning a part name and a part number to each group data are executed. The CAD data generation device receives the designated layout data and outputs CAD data through the various procedures.

  The group is composed of a part object (part shape, attribute information such as part identification information, part number, part name), a construction drawing part object (work drawing shape, character), and other added primitives.

  FIG. 3 is an example of a screen display (before arrangement adjustment) of the CAD apparatus according to the present embodiment. The CAD device reads the CAD data and displays it on the display 14. Since FIG. 3 is before the placement adjustment of the part name and the part number, the part name and the part number are difficult to see because they overlap the primitives constituting the part. For this reason, the user moves the part name and the part number so as not to overlap the primitive constituting the part by using the movement of the object which is a basic function of the CAD apparatus. FIG. 4 is an example of a screen display (after the arrangement adjustment) of the CAD apparatus according to the present embodiment. Since FIG. 4 is after the placement adjustment of the part name and part number, the part name and part number do not overlap with the primitives constituting the part. The dotted line in FIG. 4 indicates the moved part name and part number. It should be noted that the output position of the dimension line can be specified when CAD data is generated, and the four directions of upper, right, lower and left can be specified. 3 and 4 are cases where dimension lines are output in all four directions.

  FIG. 5 is an explanatory diagram of a drawing arrangement origin and a component arrangement origin according to the present embodiment. In FIG. 5, the drawing arrangement origin is ●, and the part arrangement origin is ◎. The drawing placement origin is indicated by a line segment primitive. The attribute / shape of this primitive is, for example, that the affiliation layer is “EXT”, the line type number is “14 (transparent line)”, the line color number is “5 (green)”, and the line length is “ 1.0 [mm] ". Therefore, searching for such a primitive in CAD data and acquiring the position of this primitive is the same as acquiring the position of the drawing layout origin. The component placement origin is the vertex of the extent of the entire primitive. The extent is a rectangle and there are four vertices, but any vertex can be used as long as they are unified. In this embodiment, the vertex is the lower left vertex. The vertex at the lower left is the shortest distance from the drawing placement origin. The component placement origin is not specified by a primitive like the drawing placement origin. By obtaining an extent from the primitives constituting the group and obtaining the vertex of the extent, the placement origin of the part can be found. It should be noted that a method of clearly indicating the arrangement origin of parts with a primitive may be applied to this embodiment.

  FIG. 6 is an example of a screen display (layout change) of the layout apparatus according to the present embodiment. FIG. 6 shows an example in which the user changes the opening size of the wall cabinet corresponding to the floor cabinet as shown by the dotted line portion of FIG. 6 using the layout device from the layout of FIG. Specifically, the opening size was changed from 300 [mm] to 450 [mm]. For example, when the customer confirms the submitted blueprints and estimates, the customer's thinking changes and the clerk is informed of a request for correction. The layout is changed on the layout device. After correcting the layout by operating the layout device, CAD data is generated using the CAD data generation device. By doing so, the corrected CAD data reflecting the customer's request is generated. In this embodiment, when the CAD data is generated, the CAD data generation apparatus automatically performs the position correction of the part name and the part number performed on the design drawing before correction on the CAD device, with respect to the design drawing after correction. Therefore, when the corrected CAD data generated by the CAD device is read, the corrected design drawing reflecting the position correction to the design drawing before the correction is displayed (see FIG. 7). In FIG. 7, only the part number and part name of the part surrounded by the dotted line portion are not adjusted in position and are overlapped with the primitive.

  FIG. 8 is a flowchart of the drawing arrangement process of the CAD data generation apparatus according to this embodiment. The store clerk designates the CAD data before correction and the layout data after correction to the CAD data generation apparatus, and instructs the generation of the CAD data after correction. In response to the instruction, the CAD data device receives a predefined step 100 for acquiring group data information of the CAD data before correction, step 201 for deleting the CAD data before correction, and step 301 for arranging the CAD data after correction. Then, the defined step 400 for position adjustment of the part name / part number is performed. In step 301, the CPU 11 executes each procedure in the CAD data generation apparatus.

  FIG. 9 is a flowchart of part information acquisition processing of the CAD data generation apparatus according to this embodiment. The CPU 11 retrieves the primitive for the drawing arrangement origin from the CAD data before correction, obtains the drawing arrangement origin, and records it in the DRAM 12 (step 101). The CPU 11 reads group data from the CAD data (step 111). The part object in the group is read (step 121). Here, the part object is composed of a basic shape of a part, a part name, and a part number character, and has attribute information such as part identification information. The part name and part identification information are extracted from the group data read by the CPU 11 and recorded in the DRAM 12 (step 131). The part name here is the part name described in the attribute information attached to the object. Primitive data is read from the group data read by the CPU 11 (step 141). The CPU 11 determines whether or not the part name / part number from the layer to which the primitive is read out. As a result of the determination, if it is a part name / part number, the CPU 11 records the character contents and the arrangement coordinates in the DRAM 12 in association with the recorded part identification information (step 151). Here, the part name is a part name of a text primitive represented as a figure. It is determined whether or not all primitives in the group data read out by the CPU 11 have been checked (step 161). If it is determined that all the primitives have not been checked, the process returns to step 141. If it is determined that all the primitives have been checked, the CPU 11 obtains the vertex of the extent of the group being read out, obtains the component placement origin, and holds it (step 171). The CPU 11 reads the object in the group and holds the information (step 172). Here, an identification number such as a character object with a leader line other than the component object is held. The CPU 11 reads the single primitive in the group and holds the information (step 173). Here, the identification numbers of primitives grouped together with the part object are held by a part grouping command using graphics / characters created by the standard CAD function. At this time, the placement origin obtained by the CPU 11 is recorded in the DRAM 12 in association with the recorded component identification information. After step 171, the CPU 11 determines whether or not all groups in the CAD data have been checked (step 181). If it is determined that all groups have not been checked, the process returns to step 111. If it is determined that all groups have been checked, the predefined step 100 is completed.

  FIG. 10 is a flowchart of the part number / part name position adjustment process of the CAD data generation apparatus according to this embodiment. The CPU 11 searches for a component having the same component identification information as the component identification information recorded in the DRAM 12 (step 401). The CPU 11 determines whether there is a part having the same part identification information (step 411). If it is determined that there is no part having the same part identification information, the process proceeds to step 481 described later. If it is determined that there is a part with the same part identification information, the CPU 11 reads the group data of the part identification information from the CAD data (step 421). The CPU 11 reads the part object in the group (step 422). Primitive data is read from the group data read by the CPU 11 (step 431). The CPU 11 determines whether or not the part name / part number from the layer to which the primitive is read out. As a result of the determination, if it is a part name / part number, the CPU 11 records the character contents and the arrangement coordinates in the DRAM 12 in association with the recorded part identification information (step 441). It is determined whether or not all primitives in the group data read by the CPU 11 have been checked (step 451). If it is determined that all the primitives have not been checked, the process returns to step 431. If it is determined that all primitives have been checked, the vertex of the extent of the group read by the CPU 11 is obtained, and the component placement origin is obtained (step 461). The CPU 11 obtains the corrected displacement from the obtained component placement origin and the recorded placement coordinates of the part name and part number. The CPU 11 obtains a displacement before correction from the arrangement coordinates of the part name and part number obtained in step 151 of the same part identification information and the arrangement origin of the parts obtained in step 171. The CPU 11 compares the displacement before correction with the displacement after correction, and moves the part name / part number currently arranged by the difference in displacement (step 471). The CPU 11 adds an object in the group created before the placement (step 472). Here, a character object with a leader line other than the part object is added. The CPU 11 adds a single primitive in the group that was created before placement (step 473). Here, primitives grouped together with a part object are added by a part grouping command using graphics / characters created by a standard CAD function. Next, the CPU 11 determines whether or not all groups in the CAD data have been checked (step 481). If it is determined that not all groups have been checked, the process returns to step 401. If it is determined that all groups have been checked, the predefined step 400 is completed.

  As described above, according to the present embodiment, even if it is necessary to make a change to the design drawing, the user uses the CAD device for the design drawing after the correction is made using the layout device. The performed part name and part number position correction is automatically performed on the modified design drawing generated by the CAD data generation device, and the user again uses the CAD device for the corrected design drawing. The trouble of correcting the position can be saved. In addition, the information of the added object other than the parts can be acquired by the processing of Step 172 and Step 173, and the objects added to the conventional drawing other than the parts can be automatically added by the processing of Step 472 and Step 473. Higher user convenience can be realized.

  [Door Opening Direction] In layout diagrams (for example, FIG. 2) and design drawings (for example, FIG. 3), the alternate long and short dash line is a primitive that clearly indicates the opening direction of the door, and the diagonal line in the rectangle means a drawer type. The triangle inside means the door. In the case of a door, the door opens with the vertex facing the side shared with the primitive as the axis. Therefore, if the vertex that faces the side shared with the primitive faces the right side, it opens right, and if the vertex that faces the side shared with the primitive faces the left side, it opens left. When one component has two triangles and the vertices facing the sides shared with the triangle primitives face in the other direction, it is a double door.

(Second embodiment of the present invention)
A CAD data generation apparatus according to a second embodiment of the present invention will be described with reference to the drawings.
The CAD data generation apparatus according to the present embodiment is configured in the same manner as in the first embodiment, and further, a part number arranged in a part that exists when the same part exists in the drawing with respect to the part that has been corrected and added. In the same manner as the placement of the part name, the part number / part name is placed on the part that has been modified and added.
The parts that are corrected and added correspond to parts that the CPU 11 does not have the same part identification information in step 401 and step 411.

  Whether or not the same part exists in the drawing can be determined by comparing a part that has not been corrected and added and a part that has been corrected and added. More specifically, it is possible to determine whether or not the parts are the same by comparing the types of primitives constituting the parts and by comparing the positions of the primitives in the parts. Here, when the sizes are different, either the part that has not been corrected or added, or the part that has been corrected or added, is enlarged or reduced in accordance with the other and compared. This discrimination method is referred to as primitive discrimination.

  Further, as a method for making it easier to determine whether or not the same part exists in the drawing, part type identification information for identifying the type of the part of the symbol data constituting the layout data is also held in the CAD data. By configuring, there is a method for comparing parts repair identification information between parts that have not been modified and added and parts that have been modified and added. This discrimination method is referred to as symbol discrimination.

  In the present embodiment, a step of specifying a corrected and added part, a step of determining whether or not the same part exists in the drawing, and a step of arranging a part number and a part name (steps 421 to 473) Can be implemented by performing the steps after step 481 of the first embodiment. Here, the reason why the steps are performed after step 481 is to identify the parts that have been corrected and added after step 401 and step 411.

  As described above, according to the present embodiment, when the parts are the same type as the parts already existing in the existing diagram among the corrected and added components, as in the case of the part number / part name of the component in the existing diagram, You can correct the position of the part number / part name of the part you have added and corrected. The position can be automatically corrected, and the convenience is higher.

  [Application to similar parts] In this embodiment, the position of the part number and the part name is corrected when the existing part is the same as the part that has been corrected and added. However, the position is also corrected when the parts are similar to each other. The convenience of the user is improved by appropriately correcting the position of more parts.

  The determination of whether or not the parts are similar can be realized by relaxing the comparison criteria in the case of primitive determination. That is, in the case where they are the same, the types and positions of all the primitives are the same, but in the case of similarities, the determination can be made on the condition that the types and positions of some of the primitives are the same.

  In the case of symbol discrimination, it is possible to determine whether or not parts are similar by changing the method for giving part type identification information in the layout device. That is, the format may be such that not only the component type identification information is the same, but also the similarity can be determined. Specifically, it can be realized by assigning whether or not the last two digits of the component type identification information consisting of ten digits are similar to each other. When all the digits are the same, it can be determined as a similar part.

  Here, the position adjustment by the same parts and the position adjustment by the similar parts can be clearly divided and simulated, and the position adjustment by the parts similar to the user can also be a desired position adjustment. If the position adjustment is made, the position adjustment is actually reflected. Conversely, when the desired position adjustment is not made, the position adjustment is not actually reflected.

  [Granting Component Identification Information (or Component Type Identification Information)] In this embodiment, component identification information (or component type identification information) is given by the layout device, but the CAD data is sent to the CAD device without using the layout device. Even if it is created by CAD, CAD data can be created using a component (symbol), and component identification information (or component type identification information) is given at the timing of using this component (symbol).

[Recording of the position of the part number / part name in the part] In the present embodiment, the case of the conventional drawing and the layout diagram after the correction has been described. However, when the user corrects the position of the part number / part name of the part. The coordinates of the part number and part name of the corresponding part are recorded in the storage means, and when the part holding the coordinates is used in the layout device, the coordinates recorded at the time of CAD data generation The part number / part name can be arranged based on Here, although the case where the layout apparatus is used, the case where the layout apparatus is not used may be used in the CAD apparatus.

  [Relocation other than Part Number / Part Name] In each of the above embodiments, the position adjustment for the part number and the part name has been described. However, if the user needs a primitive (position adjustment primitive) that requires position adjustment. The position can be adjusted. Specifically, the objects other than the part number and the part name that need to be adjusted include comments such as dimension lines, part prices, parts suppliers, and cautions when constructing parts.

  [Updating Attributes of Position Adjustment Primitive Color, Font, Line Type, etc.] In each of the above embodiments, only the position adjustment of the position adjustment primitive was mentioned. Values for attributes such as color, font, line type, etc. are acquired in the same way as coordinates, and attributes such as color, font, line type, etc. of the position adjustment primitive of the corresponding part of the new drawing or target CAD data are the same as the relative position difference. It can also be configured to update to the value acquired in the step. Although the position adjustment primitive is used, it may be configured to update only the attributes such as the color, font, and line type of the position adjustment primitive without the position adjustment.

  [Link] In each of the above embodiments, the part number and the part name are described as an example of an object that needs position adjustment in a group. However, even an object outside the group has a relationship with a certain group, for example, a link. Primitives can also be executed as position adjustments in such groups. For example, there is a comment as a component having a link relationship, although it is not a component in the group.

  [Expansion or reduction of parts] In the above-described embodiments, when the parts are of the same type or similar, but the sizes are different, the parts of the existing drawing are combined with the parts of the new drawing to enlarge or reduce the size. Thereafter, the position of the part of the new drawing can be adjusted by the difference in the position of the part.

  [Door Opening Direction] In each of the above embodiments, the position adjustment primitive is forced to be corrected by a one-dot chain line primitive that clearly indicates the door opening direction. This is because the primitive that clearly indicates the door opening direction is located at the center of the part, and thus the position correction of the position adjustment primitive is often greatly affected. Therefore, in addition to the part identification information or part type identification information, the group data also holds information for identifying primitives that clearly indicate the door opening direction (left opening, right opening, double door opening, drawer), so that the parts are corrected. Even if the door opening direction is not changed, the position of the position adjustment primitive is corrected in the same way as the parts in the existing figure, and if the door opening direction is changed, the position adjustment of the position adjustment primitive is not performed. It can also be configured.
