Description

The present invention relates to a design support system and program for linking different types of CAD, which enables data exchange between different types of CAD software without losing attribute information in CAD data.

CAD software used in recent years includes AUTOCAD (registered trademark), ARCHICAD (registered trademark), and REVIT.
These CAD software usually edit CAD data in their own file formats (dedicated data formats).
On the other hand, when CAD data is exchanged between multiple parties, such as between a contractor and an ordering party, there will be no problem if both parties can use the same CAD software. If there is no environment in which the software can be used, it is common to exchange via intermediate files that can be handled on each other's CAD software (see Patent Document 1 and Non-Patent Document 1).

For example, a contractor who only has the authority to use AUTOCAD can download CAD data in a dedicated data format with extensions such as [.dwg], [.dwf], [.dwfx], etc. using [.dxf] [.ifc] on AUTOCAD. ] to a highly versatile intermediate file, and send it to the orderer.
The ordering party, which has only the authority to use REVIT, imports (reads) the received intermediate file, converts it into its own dedicated data format [.rvt], and edits it.
The orderer exports the edited CAD data [.rvt] so as to convert it into the above-mentioned intermediate files [.dxf] and [.ifc], and sends them to the orderer.
In this way, data is exchanged between the sender and receiver of CAD data via intermediate files as appropriate.

Japanese Patent Application Publication No. 11-66110

https://www.fact-cam.co.jp/document/column/archives/000266.html#:~:text=DWF%E3%83%BBDXF%E3%83%BBDWG,%E3%81%A8% E3%81%97%E3%81%A6%E7%94%A8%E3%81%84%E3%82%89%E3%82%8C%E3%81%A6%E3%81%84%E3% 81%BE%E3%81%99%E3%80%82 "What is a CAD intermediate file? An essential format for communicating with business partners"

This exchange using intermediate files has a problem in that the information contained in the proprietary data format of one's own CAD software is not completely reflected in the exported intermediate file.
For example, when a contractor rents temporary structures such as scaffolding and shoring, parts (pillars, horizontal members, cloth boards, etc.) included in the CAD data model created using CAD software at the client's request. ), data indicating the shape of the part (hereinafter also referred to as "shape data") is linked to the attribute information of the part (accumulation location, section number, section name, product number, layer name, etc.). The contractor calculates the cost of the temporary structure based on the finalized design drawings using the attribute information linked to each part.

If this CAD data is exported to an intermediate file and sent to the ordering party, the intermediate file will contain only the shape data of each part and the attribute information of each part will be lost. When the design drawings are edited, the contractor side that receives the edited CAD data has a problem in that it is no longer possible to perform cost estimation using the original attribute information.

Due to the above-mentioned problem, the contractor side restricts the editing of CAD data to the orderer who does not have the same CAD software authority as the orderer, and does not accept verbal correction instructions from the orderer or printed designs. The company accepts handwritten correction instructions for drawings, and the contractor edits the CAD data in accordance with these correction instructions.

Note that one possible solution to the above problem is to have the ordering party also introduce the CAD software used by the ordering party.
However, CAD software is very expensive, and it is difficult for small and medium-sized companies to install it easily.
Additionally, the order recipient is hesitant to request the orderer to install new CAD software for their own reasons, so this is not a realistic solution.

Additionally, as the number of CAD software used increases to three or four, as the number of people with the authority to view and edit CAD data increases, it becomes difficult to maintain consistency between the dedicated data formats of each CAD software. , the situation is such that discrepancies are likely to occur in the exchange of data via intermediate files.
Additionally, depending on the specific CAD software and type of intermediate file, the entire model, which is a combination of multiple parts in the CAD data, may be exported as a single shape data, and the ordering party may not even be able to edit it. there were.

Therefore, one of the objects of the present invention is to provide a means for improving the convenience of exchanging CAD data between different types of CAD.

The present invention, which was made to solve the above problems, is a design support system that enables exchange of CAD data between different CAD software, and includes at least a storage section, an export section, and an import section, and includes the The storage section stores at least shape data of parts that can be placed on the drawing of the CAD software, and attribute information and placement information that are linked to the parts placed on the drawing of the CAD software. The export unit outputs, in a table format, a group of records obtained by converting the CAD data editable by one of the CAD software into a record in a manner including attribute information and arrangement information of the part as data items for each part. The import unit has a function of generating a collaboration file, and the import unit reads the record group of the collaboration file generated by the export unit, and stores each record in the storage unit based on the attribute information. a process of associating the attribute information with the shape data of the part acquired from the above, and a process of arranging the part related to the shape data at a predetermined position on the drawing of the other CAD software based on the placement information. The present invention is characterized in that it has a function of generating CAD data that can be edited on the other CAD software.
Further, in the present invention, the export unit converts the placement information included in the cooperation file into placement standards of a specific CAD software in advance, and the import unit converts the placement information included in the collaboration file into placement standards of the specific CAD software. The configuration may further include a function of converting the placement information included in the collaboration file into placement standards of the one CAD software based on the above.
The present invention also provides a drawing of CAD software that displays CAD data generated from either record group among the two record groups by the comparison unit that compares the two read record groups, and the import unit. The above configuration may further include a highlighting section that highlights the shape data of the changed part based on the comparison result by the comparing section.
Further, the present invention can be configured such that the collaboration file includes a plurality of the record groups.
Further, the present invention can be configured to further include an updating section having at least one function of changing, adding, or deleting the shape data recorded in the storage section.
Further, the present invention can be configured such that the collaboration file is output in csv format.
Further, the present invention can be configured such that each part recorded in the storage section is a component of a temporary structure such as a scaffold or a support.
Further, in the present invention, the linkage file further includes type information of the CAD software on the export side, and the import unit imports the linkage file into the linkage file based on the type information included in the linkage file. The configuration may further include a function of converting the placement information included in the CAD software into a placement standard of the one CAD software.

In this embodiment, the CAD data to be handled is assumed to be a 3D model of a temporary structure such as a scaffold or a support.
The information processing device is assumed to be a terminal such as a server, PC, tablet, or smartphone. These terminals include a CPU (processing unit), a data transmission/reception interface, a storage device such as an HDD or SSD, a memory such as ROM or RAM, an input device such as a keyboard, a mouse, a touch panel, a display, a display device such as a touch panel, It is equipped with optional hardware resources such as

Each design support system according to this embodiment is configured to include at least a storage section 10, an export section 20, and an import section 30.
Each part is realized by having functions built into the information processing apparatus in advance, or by installing a program into the information processing apparatus after the fact.
The details of each part will be explained below.

<2> Storage section (Figure 1)
The storage unit 10 has a function of storing at least the shape data of each part that can be placed on the drawing of the CAD software, and attribute information and placement information that are linked to the parts placed on the drawing of the CAD software. .
As the storage unit 10, a storage device such as an HDD or an SSD included in the information processing device can be used.
Furthermore, the present invention is not limited to unifying the storage locations of shape data, attribute information, and arrangement information.

<2.1> Shape Data Shape data is data that specifies the shape of each part that can be placed on a drawing of CAD software.
Usually, CAD software has a function to add a parts library arbitrarily, and the shape data according to the present invention corresponds to the data stored in this parts library.
Information (identification information) for identifying each part is attached to each shape data, and this identification information is also included in the parts placed on the CAD software.

<2.1.1> Update of shape data When new parts handled by CAD software are added, the additional shape data can be manually added to the storage section by the user, or the update section (provided separately) ), additional shape data may be automatically downloaded from an external cloud server or the like via a network.

<2.2> Attribute information (Table 1)
Each part arranged on a drawing of CAD software is associated with attribute information including the above-mentioned identification information.
The user can view and edit attribute information for each part using the property display function on the CAD software.
The contents of the items included in the attribute information may be determined as appropriate depending on the contents of the CAD data, the job type of the person concerned, etc., and are not particularly limited in the present invention.
In this embodiment, examples of items included as attribute information are shown in Table 1 below.

As in this example, each part in the CAD data is a component of a temporary structure such as a scaffold or shoring (column, beam frame, handrail, bracket, scaffold board, etc.), and the temporary structure is rented. When it is assumed that CAD data is exchanged between the contractor and the orderer, the attribute information may be configured to include various information mainly used for cost estimation work on the contractor's side.

<2.3> Location information (Table 2)
For each part of CAD data arranged on a drawing of CAD software, the arrangement mode (part insertion point, extrusion direction, mirror) can be expressed as numerical arrangement information.
In this embodiment, examples of items included as placement information are shown in Table 2 below.

<3> Export section (Figure 1)
The export unit 20 has a function of generating a collaboration file 21 from CAD data in response to an export execution command from a user.

<3.1> Linkage files (Table 3)
The collaboration file 21 is a file used in the design support system A in which different CAD software is installed to generate CAD data that can be edited with the different CAD software.
In this embodiment, the collaboration file 21 is configured to include attribute information and placement information linked to each part of CAD data.
The collaboration file 21 is output in a tabular format useful for ensuring compatibility, and it is preferable to use the commonly used csv format as the tabular format.
Tables 3 and 4 below show a part of the csv format linkage file output in table format (for convenience of display, the items following the right column of Table 3 are shown in Table 4).

The collaboration files 21 shown in Tables 3 and 4 are configured with attribute information and placement information as column items, and one part as one line. In the title line, the item names of attribute information (product number to leasing company) and placement information (insertion shop X to mirror Z) are listed, and from the second line onwards, attribute information and placement information for each part are listed.
In the present invention, a collection of records for each part is defined as a record group.

<3.2> How to output placement information (Table 3)
In this embodiment, the arrangement information included in the collaboration file 21 is based on the arrangement information of the CAD software used on the export side, regardless of the type of CAD software used on the export side, in accordance with the arrangement standards of the specific CAD software. We use numerical values that have been converted in the form of In this case, the import unit 30, which will be described later, uses a prepared conversion formula to conform to the layout standards of the importing CAD software, assuming that the values comply with the layout standards of the specific CAD software mentioned above. Then, appropriate conversion processing will be performed.

<3.3> Others Note that the present invention is not limited to a configuration in which all of the attribute information and arrangement information stored in the storage unit 10 described above is included in the collaboration file 21, but only some of the information is included. The configuration may be such that it is included in the collaboration file 21.

<4> Import section (Figure 1)
The import unit 30 has a function of generating CAD data that can be edited on the CAD software on the import side from the collaboration file 21 generated by the export unit 20.
The processing contents of the import unit 30 according to this embodiment are as follows.

<4.1> Reading the collaboration file The collaboration file 21 generated by the export unit 20 is read, and a predetermined record group is extracted from the collaboration file 21.
In this embodiment, since the collaboration file 21 includes only one record group, no determination process is performed to extract a predetermined record group.

<4.2> Acquisition of Shape Data/Associating Attribute Information For each record in the record group, the shape data of the corresponding part is acquired from the storage unit 10 based on the attribute information of the record.
In this embodiment, the shape data of the corresponding part is acquired based on the "product number" item in the attribute information.

<4.3> Linking attribute information to shape data Attribute information is linked to the acquired shape data.

<4.4> Placement of parts based on placement information Parts related to the acquired shape data are placed on the drawing of the CAD software based on the placement information.
At this time, if the type of CAD software set as a placement standard for placement information and the CAD software on the importing side are different, the CAD software on the importing side is compatible based on the conversion formula provided by the importing unit 30. The parts are placed on the drawing based on the information obtained by converting the placement information so that the parts are placed on the drawing.

<4.5> Generating CAD data Repeat the processes from <4.2> to <4.4> above for all records in the read record group, and create all the records on the drawing of the importing CAD software. Place parts and generate CAD data.
The generated CAD data is in a state where it is possible to edit the layout and attribute information for each part using CAD software on the import side.

<5> Usage image (Figures 2 to 4)
Next, an image diagram of how the design support system according to this embodiment is used will be described.

<5.1> Basic screen (Figure 2)
On the basic screen according to this embodiment, a button for executing an export task is displayed in the "Add-in" column in the menu of the CAD software (one CAD software) installed in the information processing device that constitutes the design support system.

By selecting the save destination for the collaboration file from this screen, the export unit 20 will be able to perform the collaboration. file 21 is exported to a predetermined storage location.
The user on the export side attaches this linkage file 21 to an email or the like and sends it to the user on the import side.

<5.3> Work on the import side (Figure 4)
When the importing user selects the import button B2 with the CAD software (the other CAD software) open, a collaboration file selection screen E is displayed. The user selects the collaboration file 21 received by e-mail or the like.
After selecting the collaboration file 21, the import unit 30 generates CAD data that can be edited by the importing CAD software (the other CAD software) from the collaboration file 21, and displays it on the drawing of the CAD software. .

<6> Other Modifications In this embodiment, it was assumed that CAD data is exchanged between two information processing devices owned by different users, but the present invention It can also be used to exchange CAD data between processing devices.
Furthermore, the present invention can also be used when a plurality of CAD software programs are installed in one information processing device and CAD data is exchanged between the CAD software programs.

Other output examples will be shown regarding the arrangement information included in the collaboration file described in the first embodiment.

<1> Output example 1 (fixed to the CAD software on the export side)
A configuration may be considered in which the numerical values of the arrangement information in the CAD software used on the export side are directly applied as the arrangement information of the collaboration file 21.
In the case of this output example, the import side needs to know the type of CAD software on the export side, so the file name of the linkage file 21 and the CAD software on the exporter's side are written as the title line in the linkage file 21. A possible method is to include the type information of the CAD software on the export side as one of the record items in the collaboration file 21, and to refer to these in the import section.

<2> Output example 2 (optional selection by user)
Regardless of the type of CAD software used on the export side, by selecting the CAD software on the import side by the user, the export unit 20 can convert numerical values that have been processed in accordance with the layout standards of the selected CAD software. A configuration may be considered in which this information is applied as the arrangement information of the collaboration file 21.
In the case of this output example, the export unit 20 is configured to have a conversion formula for placement information between each CAD software, and the import side places each part by applying the placement information of the linkage file as is. , and generate corresponding CAD data.

<1> Overall configuration (Figure 5)
FIG. 5 is a diagram showing the overall configuration of the design support system according to this embodiment.
The design support system according to this embodiment has a configuration that includes a comparison section 40 and a highlighting section 50 in addition to the storage section 10, export section 20, and import section 30 described above.
Details of the comparison section 40 and the highlighting section 50 will be described below.

<2> Comparison section (Figure 5)
The comparison unit 40 has a function of comparing text data in two read record groups.
The two record groups to be read may each be read from separate collaboration files 21, or a single collaboration file 21 may include a plurality of record groups as in Example 4, which will be described later. In this case, the configuration may be read from a single collaboration file 21.
The comparison process by the comparison unit 40 can be performed using a file comparison command provided in advance by the OS of the information processing device, other text comparison tools, or the like.

<3> Highlighted area (Figure 5)
The highlighting section 50 has a function of highlighting, on the CAD drawing, the shape data of the part that has been changed based on the comparison result by the comparing section 40 .
The CAD data displayed on the CAD drawing is the CAD data generated by the import unit from one of the two record groups to be compared.
As a mode of highlighting, it is possible to use a change in color, a blinking display, a change in the thickness of the outline, etc. for the part where the difference has occurred.

<4> Usage image (Figure 6, Figure 7)
Next, an image diagram of how the design support system according to this embodiment is used will be described.

<4.1> Basic screen (Figure 6)
In the basic screen according to this embodiment, in addition to the export button B1 and import button B2 in the "Add-in" column of the basic screen according to the first embodiment shown in FIG. (Comparison button B3) is arranged.
On the comparison file selection screen F that is displayed after selecting this comparison button B3, specify the linkage file 21 before the change and the linkage file 21 after the change, and select the "Execute" button. 40 is executed.

<4.2> Display of comparison results (Figure 7)
After the comparison process is completed, the highlighting unit 50 displays the results of comparison between the CAD data generated from the changed linkage file 21 by the importer 30 and the pre-change linkage file 21, indicating that differences have occurred. Highlight parts.
In FIG. 7, of the CAD data C1 generated from the changed linkage file 21, the highlighted part C11 is displayed on the CAD drawing with the newly added part changed in color. There is.

<1> History preservation in collaboration file In Example 1, the generated collaboration file 21 is one record group generated based on part or all of the attribute information of each part related to the current CAD data. However, in the present invention, it is also possible to record a plurality of record groups in one collaboration file 21.
More specifically, even after CAD data is generated by importing a certain linkage file 21 on the CAD software on the import side, the linkage file 21 is stored in the background, and after editing the CAD data, it is exported. One possible method is to add a record group generated from the edited CAD data to the stored collaboration file 21 when the export unit 20 performs the export work.

<2> Method for distinguishing between record groups A method for distinguishing between multiple record groups on a single linkage file 21 is to record the export time in a line that is recognized as the title line of the tabular file. The import unit 30 recognizes these multiple record groups and imports the latest record group into the CAD data. A method may be considered in which it is possible to arbitrarily select CAD data to be generated or from which record group CAD data is to be generated.

<3> Comparison of each record group When a single collaboration file 21 includes a plurality of record groups as in this embodiment, the comparison section 40 and the highlighting section described in the third embodiment 50, the comparison unit 40 reads a single linkage file, arbitrarily selects two record groups to be compared from a plurality of record groups in the linkage file 21, and It can also be configured to display comparison results.

<1> Independent configuration of import section and export section The present invention can also be configured such that only one of the export section 20 and the import section 30 described in each of the above embodiments can be executed.
For example, if there is no need for the CAD data to be sent back and forth between the parties involved, and only confirmation of the CAD data is requested from one user to the other user, one user may have a configuration in which only the export unit 20 can be executed. The other user side can be configured to be able to execute only the import unit 30.

<2> Configuration as a program The present invention also includes an aspect of providing a program for causing a known information processing apparatus to function as a design support system according to each of the embodiments described above.
The program according to the present invention may be an add-in program that is introduced to add functionality to commercially available CAD software, or may be a program that is pre-installed in existing CAD software.
