In recent years, a CAD (Computer Aided Design) system, which is a system for designing and drawing using a computer, has become widespread. There are various types of CAD systems, and users of CAD systems often use different CADs depending on the design target or purpose. For this reason, the development of a system that enables data to be linked between a plurality of CAD systems that have been used properly is also underway. For example, Patent Document 1 is a system for linking data between an architectural CAD that designs specifications with a schematic model for the entire building and an equipment CAD that designs specifications with a detailed model for equipment installed in the building. Is disclosed.

Japanese Unexamined Patent Publication No. 2003-141191

The system disclosed in Patent Document 1 can convert the schematic model created when designing the schematic specifications in the architectural CAD into the detailed model used when designing the detailed specifications in the equipment CAD. However, the degree of consistency between the schematic model and the detailed model is not considered during this conversion. Poor consistency when converting a schematic model to a detailed model increases the number of modifications that must be made to the detailed model, making it difficult for the user to work efficiently.

The present invention has been made in view of the above circumstances, and streamlines the work of converting the schematic model created when designing the schematic specifications into the detailed model used when designing the detailed specifications. The purpose is to do.

In order to achieve the above object, the design support device according to the present invention includes a schematic model acquisition unit, a detailed model acquisition unit, a matching rate calculation unit, a matching rate display unit, and a model replacement unit. The schematic model acquisition unit acquires schematic shape information representing the shape of the schematic model for designing the schematic specifications. The detailed model acquisition unit acquires detailed shape information representing the shape of the detailed model for designing the detailed specifications. The matching rate calculation unit calculates the matching rate of both shapes based on the approximate shape information and the detailed shape information. The matching rate display unit displays the matching rate calculated by the matching rate calculation unit. The model replacement unit replaces the schematic model with a detailed model based on the matching rate calculated by the matching rate calculation unit.

According to the present invention, the design support device replaces the schematic model with the detailed model based on the matching ratio between the shape of the schematic model and the shape of the detailed model. Therefore, according to the present invention, the schematic model can be replaced with a detailed model having a high shape matching ratio. Therefore, the schematic model created when designing the schematic specifications is used when designing the detailed specifications. It is possible to streamline the work of converting to a detailed model.

It is a system to do. Here, the schematic model is a part on a CAD system used for designing a schematic specification, and as shown in FIG. 1, is mainly composed of an outer shell shape. The detailed model is a part on a CAD system used for designing detailed specifications of equipment, parts, etc., and as shown in FIG. 2, details required for producing equipment, parts, etc. It is composed of various shapes. The design data in each CAD system is configured as a collection of shape information indicating the shape of each part arranged in the design space and arrangement information indicating the position and orientation of each part in the design space. ..

As shown in FIG. 3, the design support system 1 streamlines the design of the detailed specifications by using the schematic CAD device 200 for designing the schematic specifications, the detailed CAD device 300 for designing the detailed specifications, and the design data of the detailed specifications. The design support device 100 is provided. The design support device 100 is connected to the schematic CAD device 200 and the detailed CAD device 300 so as to be able to communicate with each other via a network NW constructed by appropriately combining wired and wireless communication lines.

The schematic CAD device 200 is, for example, a building-based three-dimensional CAD system, and uses parts represented by a schematic model as shown in FIG. 1 to design schematic specifications of a building structure, equipment, equipment connection piping, wiring, and the like. It is a device to do. In FIG. 1, the placement reference represents a point and an orientation that serve as a reference for the placement position when the schematic model is placed in the design space. Information on where and in what direction this arrangement standard (also referred to as a schematic arrangement standard) exists in this schematic model is also included in the shape information of this schematic model. The information of the schematic model includes shape information (also referred to as schematic shape information) representing the shape of the schematic model as shown in FIG. 1 and layout information (also referred to as schematic shape information) indicating where and in what direction the schematic model is arranged in the design space. It includes two types of information (also called rough layout information). Then, as described above, the shape information includes not only the shape information but also information indicating where and in which direction the above-mentioned arrangement reference exists in this schematic model.

The detailed CAD device 300 is, for example, a mechanical three-dimensional CAD system, and uses parts represented by a detailed model as shown in FIG. 2 to provide detailed specifications such as the structure and arrangement of each part and the connection structure between parts. It is a device to design. In FIG. 2, the placement reference represents a point and an orientation that serve as a reference for the placement position when the detailed model is placed in the design space, similar to the placement reference in FIG. Information on where and in what direction this placement criterion (also referred to as detailed placement criterion) exists in this detailed model is also included in the shape information of this detailed model.

Further, FIG. 2 shows that this part includes a pipe support member, and the pipe support member is a member for fixing this part to another part. As an example to show that the detailed model includes such fine features, FIG. 2 illustrates a pipe support member. Not limited to this, the detailed model contains the detailed information necessary to produce the target part. Similar to the information of the schematic model, the detailed model information also includes shape information (also referred to as detailed shape information) representing the shape of the detailed model as shown in FIG. 2, and where and in which direction in the design space the detailed model is displayed. It includes two types of information, which is placement information (also referred to as detailed placement information) indicating whether or not to place the information. Then, as described above, the shape information includes not only the shape information but also information indicating where and in which direction the above-mentioned arrangement reference exists in this detailed model.

The design support device 100 calculates the matching ratio between the shape information of the schematic model and the shape information of the detailed model, and replaces the schematic model with a detailed model having a high matching ratio to streamline the design of the detailed model. It is a device.

Next, each configuration of the design support device 100, the schematic CAD device 200, and the detailed CAD device 300 constituting the design support system 1 will be described.

As shown in FIG. 4, the design support device 100 includes a control unit 110, a storage unit 120, a communication unit 130, an input unit 140, and an output unit 150. Each of these parts is electrically connected to each other via a bus line BL.

The control unit 110 includes a CPU (Central Processing Unit), and controls each component of the design support device 100 by reading and executing various operation programs stored in the storage unit 120.

Functionally, the control unit 110 includes a schematic model acquisition unit 111, a detailed model acquisition unit 112, a matching rate calculation unit 113, a matching rate display unit 114, an arrangement standard calculation unit 115, a model replacement unit 116, and a detailed model generation unit 117. Has.

The schematic model acquisition unit 111 acquires intermediate file data of design data of schematic specifications from the schematic CAD device 200 via the communication unit 130. The details of this intermediate file data will be described later, but the intermediate file data includes information on the parts of the schematic model (shape information and arrangement information of each part) included in the design data of the schematic specifications. Further, the schematic model acquisition unit 111 acquires information on various parts of the schematic model included in the acquired intermediate file data, and the schematic model storage unit 121 which describes the information (shape information and arrangement information of the parts) of the parts will be described later. Store in.

The detailed model acquisition unit 112 acquires shape information of various parts of the detailed model stored in the detailed model library 322, which will be described later, from the detailed CAD device 300 via the communication unit 130. Further, the detailed model acquisition unit 112 stores the acquired shape information of various parts in the detailed model storage unit 122, which will be described later.

As described above, in both the schematic model and the detailed model, there are two types of part information: shape information indicating the shape of the part and arrangement information indicating where and in which direction the part is arranged in the design space. Contains information. The shape information is information indicating the shape as shown in FIGS. 1 and 2. For example, the coordinate information of the points and lines constituting the part and the position (coordinates) of the above-mentioned "arrangement reference" on the part. And orientation (rotation angle) information.

The placement information is information indicating which position (x, y, z) in the design space and in which direction (φ, θ, ψ) the above-mentioned “placement reference” is placed. When the position (coordinates) information included in the placement information is (x, y, z), the origin of the "placement reference" is placed at the position (x, y, z) in the three-dimensional coordinates of the design space. As such, the parts are translated. Then, when the orientation (rotation angle) information included in the arrangement information is (φ, θ, ψ), the Y axis is rotated by φ around the X axis with respect to the XYZ axes for indicating the three-dimensional coordinates of the design space. When it is rotated by θ around and ψ is rotated around the Z axis, the part is rotated so as to be the XYZ axis of the “placement reference”. By these translation and rotation operations, the part is arranged in the position and orientation based on the arrangement information in the design space.

Returning to FIG. 4, the matching rate calculation unit 113 has a matching rate between the shape information of the parts of the schematic model acquired by the schematic model acquisition unit 111 and the shape information of the parts of the detailed model acquired by the detailed model acquisition unit 112. Is calculated. The matching ratio is 0 if the shapes do not match at all, and 1 if the shapes match completely. Any method can be adopted as the calculation method of the matching ratio, and the following method can be mentioned as an example. In this method, the parameters of the shape information of the parts of the schematic model and the parameters of the shape information of the parts of the detailed model are normalized, and then the inner product is taken as the consistency rate.

First, in preparation for calculating the consistency rate, various numerical values are defined as follows.
Npc = Number of parameters that are common to both the shape information of the parts of the schematic model and the shape information of the parts of the detailed model.
Nps = number of parameters that exist only in the shape information of the parts of the detailed model.
Npa = Number of parameters that exist only in the shape information of the parts of the schematic model (however, usually, a schematic model such that Npa = 0 is used).
Then, the sum of the numbers of all these parameters is represented by N. That is, N = Npc + Nps + Npa.

Set the individual values of the parameters as follows.
Pa [i] = value of the i-th parameter of the shape information of the parts of the schematic model (1 ≦ i ≦ Npc or Npc + Nps <i ≦ N).
Pa [i] = 0 (Npc <i ≦ Npc + Nps).
Ps [i] = value of the i-th parameter of the shape information of the part of the detailed model (1 ≦ i ≦ Npc + Nps).
Ps [i] = 0 (Npc + Nps <i ≦ N).
Here, Pa [i] and Ps [i] having a value of i in the range of 1 to Npc are common to both the shape information of the parts of the schematic model and the shape information of the parts of the detailed model. The value of the parameter to be used. (Of the commonly existing parameters, Pa [i] is the value of the i-th parameter of the shape information of the parts of the schematic model, and Ps [i] is the value of the i-th parameter of the shape information of the parts of the detailed model. Value.)

After preparing the numerical values as described above, the matching rate can be obtained by the following equation (1).

In the method described above, it is assumed that the parameter of the shape information consists of a set of coordinate information of points and lines representing the shape. Depending on the data format of the CAD system used, it is possible that the coordinate information of the points and lines representing the shape of each part cannot be directly obtained from the design data. In this case, the coordinate information of the target part is obtained from the design data and set as a parameter of the shape information of the part. In addition, if it is a CAD system, regardless of which data format is used, it is possible to finally output a drawing displaying the shape of each part, so that it is possible to obtain the coordinate information of the parts.

Returning to FIG. 4, the matching rate display unit 114 outputs each parameter of the matching rate, the shape of the part of the detailed model having the matching rate, and the shape information in descending order of the matching rate calculated by the matching rate calculation unit 113. Display at 150.

The placement standard calculation unit 115 determines the placement standard of the parts of the detailed model corresponding to the parts of the rough model based on the position and orientation of the placement reference included in the shape information of the parts of the rough model acquired by the rough model acquisition unit 111. Calculate the position and orientation of. Any method can be adopted as the calculation method of the placement standard, and the following method can be mentioned as an example of the calculation method of the placement standard in the case of Npa = 0 described above.

First, as a premise, when Npa = 0, Pa [i] has a valid value in the range of 1 ≦ i ≦ Npc, and Pa [i] = 0 in the range of Npc <i ≦ N. (In the range of 1 ≦ i ≦ Npc, Pa [i] is the shape information of the parts of the rough model among the parameters that are common to both the shape information of the parts of the rough model and the shape information of the parts of the detailed model. It is the value of the i-th parameter of.) And, if it is in the range of 1 ≦ i ≦ Npc, Ps [i] also has a valid value. (In the range of 1 ≦ i ≦ Npc, Ps [i] is the shape information of the parts of the detailed model among the parameters that are common to both the shape information of the parts of the schematic model and the shape information of the parts of the detailed model. It is the value of the i-th parameter of.)

By rotating and translating the parts of the detailed model, Ps [i] can be changed without changing the shape of the parts of the detailed model. Therefore, the detailed model is rotated and translated so that Pa [i] and Ps [i] match as much as possible within the range of 1 ≦ i ≦ Npc. Then, the position and orientation of the "arrangement reference" included in the shape information of the parts of the schematic model can be set to the position and orientation of the "arrangement reference" to be included in the shape information of the parts of the detailed model.

The placement standard calculation unit 115 calculates not only the shape matching rate but also the "placement standard" to be included in the shape information of the detailed model based on the "placement standard" included in the shape information of the schematic model. , It is possible to perform substitution with increased positional matching rate.

Returning to FIG. 4, the model replacement unit 116 replaces the parts of the schematic model acquired by the schematic model acquisition unit 111 with the parts of the detailed model having the highest matching rate calculated by the matching rate calculation unit 113. When replacing, the position and orientation of the placement reference calculated by the placement reference calculation unit 115 are replaced according to the position and orientation of the placement reference of the parts of the original schematic model.

The detailed model generation unit 117 uses the information of the detailed model parts stored in the detailed model library 322, which will be described later, to change a part of the parameters of the shape information of the parts, thereby making a new part of the detailed model. Generate shape information of. The detailed CAD device 300 may include the detailed model generation unit 117 instead of the design support device 100.

Further, the storage unit 120 functionally includes a schematic model storage unit 121, a detailed model storage unit 122, and a design data storage unit 123. The schematic model storage unit 121 stores the shape information and the arrangement information of the parts of the schematic model acquired by the schematic model acquisition unit 111.

Further, the schematic design data generation unit 211 stores the generated design data of the schematic specifications in the schematic design data storage unit 221 described later. The schematic specification design data is data in which the schematic specifications of the building structure, equipment, equipment connection piping, wiring, etc. are designed using the parts represented by the schematic model.

The intermediate file generation unit 212 generates intermediate file data obtained by converting the design data of the schematic specifications stored in the schematic design data storage unit 221 into a data format that can be read by another device. This intermediate file data includes shape information and arrangement information of the parts of the schematic model included in the design data of the schematic specifications. Further, the intermediate file generation unit 212 transmits the generated intermediate file data to the design support device 100 via the communication unit 230, which will be described later.

The data format of the intermediate file data is arbitrary as long as it is a data format that can be handled by another device, but for example, a DXF (Drawing Exchange Form) format is used. In addition, the IFC (Industry Foundation Classes) format proposed by IAI (International Alliance for Industry Foundation) can also be used. Since the intermediate file data can be handled by a device other than the approximate CAD device 200, for example, the detailed CAD device 300 can read the intermediate file data and store it as design data of detailed specifications in the detailed design data storage unit 321 described later. .. However, since this intermediate file data is originally the design data of the schematic specifications, the design data of the detailed specifications stored in the detailed design data storage unit 321 here actually has only the same accuracy as the design data of the schematic specifications. There will be no.

The storage unit 220 includes a semiconductor memory such as a RAM and a ROM, a hard disk drive, and the like.

The control unit 310 functionally includes a detailed design data generation unit 311, a detailed model transmission unit 312, and a detailed model reception unit 313.

The detailed design data generation unit 311 generates design data of detailed specifications of the three-dimensional CAD based on the user's operation, data input, and the like received by the input unit 340, which will be described later. Further, the detailed design data generation unit 311 stores the generated design data of the detailed specifications in the detailed design data storage unit 321 described later. The detailed specification design data is data in which detailed specifications such as the structure and arrangement of each part and the connection structure between parts are designed using the parts represented by the detailed model.

The detailed model transmission unit 312 transmits information on the parts of the detailed model stored in the detailed model library 322, which will be described later, to the design support device 100 via the communication unit 330, which will be described later.

The detailed model receiving unit 313 receives information on new parts of the detailed model generated by the detailed model generating unit 117 of the design support device 100, and stores the information in the detailed model library 322 described later. When the detailed model generation unit 117 is provided by the detailed CAD device 300 instead of the design support device 100, the detailed model receiving unit 313 is unnecessary, and the detailed model generation unit uses the information of the generated detailed model parts in the detailed model library. Store in 322.

The storage unit 320 includes a semiconductor memory such as a RAM and a ROM, a hard disk drive, and the like. Further, the storage unit 320 functionally includes a detailed design data storage unit 321 and a detailed model library 322.

As described above, the detailed design data storage unit 321 stores the design data of the detailed specifications generated by the detailed design data generation unit 311.

The communication unit 330 includes a NIC, an antenna, and the like for data communication with an external device via the network NW. For example, the communication unit 330 transmits the shape information of the parts of the detailed model to the design support device 100 under the control of the detailed model transmission unit 312.

The output unit 350 includes a display device such as an LCD, PDP, or organic EL display, a printer, a speaker, and the like, and outputs, for example, the contents of a drawing based on design data of detailed specifications.

As described above, the detailed CAD device 300 can read the intermediate file data generated by the schematic CAD device 200, but the detailed specification design data obtained by reading the intermediate file data is the schematic specification design data. It has only the same accuracy. In such a case, the design support device 100 performs a design support process, which is a process for streamlining the work of replacing the design data of the schematic specifications with the design data of the detailed specifications for each part in the design data. The design support process executed by the design support device 100 will be described with reference to the flowchart shown in FIG. 7.

First, as a preparation before performing the design support process, the user shall generate the intermediate file data in the approximate CAD device 200 and read the intermediate file data in the detailed CAD device 300. Then, the detailed CAD device 300 stores the design data having only the same accuracy as the design data of the schematic specifications in the detailed design data storage unit 321. Now that the preparation is complete, the control unit 110 of the design support device 100 then responds to an instruction from the user (for example, activation of application software for design support processing mounted on the design support device 100). , Start execution of design support processing.

When the control unit 110 starts the design support process, first, the schematic model acquisition unit 111 reads the intermediate file data generated by the intermediate file generation unit 212 of the schematic CAD device 200 via the communication unit 130. Then, the entire design data of the schematic specifications obtained from the intermediate file data is stored in the design data storage unit 123. Then, the schematic model acquisition unit 111 acquires information on various parts of the schematic model (shape information and arrangement information of the parts) included in the intermediate file data, and stores the information in the schematic model storage unit 121 (step S101). Usually, the schematic specification is designed by combining a plurality of parts, so that the intermediate file data, which is the design data of the schematic specification, includes the information of the plurality of parts. The schematic model acquisition unit 111 stores all the information of these plurality of parts in the schematic model storage unit 121.

Then, the schematic model acquisition unit 111 selects one part from the plurality of parts of the schematic model stored in the schematic model storage unit 121, and acquires the shape information of the parts of the schematic model (step S102). This step S102 is also referred to as a schematic model acquisition step. The selection of the parts in step S102 may be a mechanical selection such as selecting the parts in the order of appearance in the intermediate file data, or the input unit 140 accepts the input of the parts desired by the user and selects the parts. Manual selection such as selection may be used.

Next, the detailed model acquisition unit 112 acquires the information of the detailed model library 322 of the detailed CAD device 300 via the communication unit 130, and details from the various parts of the detailed model stored in the detailed model library 322. Select one part of the model. This selection may be made one by one in an arbitrary order so that all the parts of the detailed model stored in the detailed model library 322 can be taken out one by one. For example, select one by one in the order of registration in the detailed model library 322, the order of part numbers, and the like. Then, the detailed model acquisition unit 112 acquires the shape information of the selected detailed model part from the detailed model library 322 via the communication unit 130 and stores it in the detailed model storage unit 122 (step S103). This step S103 is also referred to as a detailed model acquisition step.

Next, the matching rate calculation unit 113 determines the matching rate between the two shapes based on the shape information of the parts of the schematic model selected in step S102 and the shape information of the parts of the detailed model selected in step S103. Calculate (step S104). This step S104 is also referred to as a matching rate calculation step. Any method can be adopted as the method for calculating the matching rate, and for example, an example described in the above description of the matching rate calculating unit 113 can be adopted.

Next, the control unit 110 determines whether or not all the parts of the detailed model stored in the detailed model library 322 have been selected (step S105). This determination can be made by the control unit 110 acquiring the information of the detailed model library 322 via the communication unit 130.

If all the parts stored in the detailed model library 322 have not been selected yet (step S105; No), the process returns to step S103. If all the parts have been selected (step S105; Yes), the matching rate display unit 114 displays the matching rate and each parameter of the shape and shape information of the parts of the detailed model having the matching rate in descending order of the matching rate. Is displayed on the output unit 150 (step S106). This step S106 is also referred to as a consistency rate display step.

In step S106, when the number of detailed model parts selected from the detailed model library 322 is large, even if the reference display number (for example, 10 pieces, 20 pieces, etc.) is displayed in order from the one with the highest matching rate. good. Also, instead of displaying a specific reference number, the number that can be viewed on one screen is limited to the number that can be viewed on one screen according to the screen size, character size, number of shape information parameters, etc. You may.

Further, for each parameter of the shape information of the part of the detailed model, the matching rate display unit 114 is the difference information from each parameter of the shape information of the part of the schematic model (selected in step S102) as a reference at the time of calculating the matching rate. May be displayed. By displaying the difference information on the matching rate display unit 114, the user can grasp the magnitude of the degree of matching of each parameter, which can be referred to when inputting the parameter change value in the parameter change described later. it can.

Next, the control unit 110 determines whether or not to change the parameter (step S107). In this determination, it may be determined whether or not there is a parameter change instruction from the user, and if the maximum value of the matching rate calculated in step S104 is less than the reference matching rate (for example, 0.7), it is determined that the parameter is changed. You may. If the maximum matching ratio is less than the reference matching ratio, the shapes do not match very well, and problems may occur when replacing the schematic model with such a detailed model with a low matching ratio. ..

When the parameter is changed (step S107; Yes), the input unit 140 accepts the input of the parameter change value from the user (step S111). At this time, the user refers to the value of each parameter of the shape information displayed in step S106, and changes the parameter so that the shape matches the part of the schematic model as much as possible.

Then, the detailed model generation unit 117 generates shape information of a new part of the detailed model based on the value of the parameter input in step S111 (step S112). Each time the user inputs a parameter change value in step S111, it is possible to present to the user in an easy-to-understand manner how the shape of the part of the detailed model changes due to the parameter change. For that purpose, the output unit 150 may display the part shape based on the shape information generated by the detailed model generation unit 117 in step S112. In this case, the input of the parameter change value in step S111 and the detailed model generation and display in step S112 can be repeated until the user is satisfied.

Next, the detailed model generation unit 117 transmits the shape information of the generated new part to the detailed CAD device 300 via the communication unit 130 (step S113), and ends. In the detailed CAD device 300, the detailed model receiving unit 313 receives the shape information of the new part of the detailed model transmitted from the design support device 100 and stores it in the detailed model library 322.

On the other hand, when the parameters are not changed (step S107; No), the model replacement unit 116 selects the parts of the detailed model based on the matching ratio (step S121). In this selection, the model replacement unit 116 usually selects the parts of the detailed model having the shape information having the highest matching ratio, but other parts can also be selected based on, for example, the user's instruction.

Next, the placement reference calculation unit 115 calculates the placement reference of the parts of the detailed model selected in step S121 (step S122). This step S122 is also referred to as a placement reference calculation step. Any method can be adopted as the method for calculating the arrangement standard, and for example, an example described in the above description of the arrangement standard calculation unit 115 can be adopted.

Next, the model replacement unit 116 uses the design data stored in the design data storage unit 123 to convert the parts of the schematic model selected in step S102 into the parts of the detailed model selected in step S121 in step S122. It is determined whether or not the replacement is possible with reference to the placement standard calculated in (step S123).

If the matching rate is high, the replacement is usually possible, but it is also possible that the pipe support member as shown in FIG. 2 interferes with other parts and cannot be physically replaced. Further, when the matching ratio is low, it is conceivable that a portion that is not a protrusion such as a pipe support member also interferes with another portion. Therefore, the model replacement unit 116 uses the design data stored in the design data storage unit 123 to temporarily replace the part, and whether or not the replaced part interferes with other parts in three dimensions. To judge. Then, if it interferes, it is determined that it cannot be replaced, and if it does not interfere, it is determined that it can be replaced. By making this determination, it is possible to prevent the parts from being replaced with unusable parts because they actually interfere with other parts even if the matching rate is high.

When the model replacement unit 116 determines that the part cannot be replaced (step S123; No), the output unit 150 displays information that the part cannot be replaced (step S124), and the process ends. When the model replacement unit 116 determines that the part can be replaced (step S123; Yes), the output unit 150 displays the information that the part can be replaced, and the design data stored in the design data storage unit 123 is used. The parts of the schematic model selected in step S102 are replaced with the parts of the detailed model selected in step S121 with reference to the placement reference calculated in step S122 (step S125). This step S125 is also referred to as a model replacement step. Further, the replacement information is transmitted to the detailed CAD device 300 via the communication unit 130. Upon receiving the replacement information (information indicating which schematic model is to be replaced with which detailed model), the detailed CAD device 300 replaces the schematic model in the design data stored in the detailed design data storage unit 321. Replace with the detailed model of interest. Then, the control unit 110 ends the design support process.

As described above, according to the present embodiment, the design support device 100 efficiently replaces the parts included in the schematic specifications designed by the schematic CAD device 200 with the parts having detailed specifications having a high consistency rate. Can be transformed into.

Further, since the design support device 100 displays the matching rate, the user can efficiently proceed with the work of converting to the detailed model by referring to the matching rate. Further, the design support device 100 can generate shape information of a new part of the detailed model in response to a parameter change instruction by the user. This allows the user to use parts of the detailed model with higher consistency.

The present invention is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the gist of the present invention.

For example, in the above embodiment, the design support device 100 is a separate device capable of communicating with the schematic CAD device 200 and the detailed CAD device 300. However, for example, the detailed CAD device may include the configuration and functions included in the design support device 100, and in this case, communication between the detailed CAD device and the design support device 100 becomes unnecessary. Then, in this case, it is possible to improve the efficiency of the design of the parts of the detailed model by using the intermediate file data generated by the approximate CAD device 200 only with the detailed CAD device.

In the above embodiment, the operation program executed by the CPU of the control unit 110 is stored in the ROM in advance. However, the present invention is not limited to this, and by implementing an operation program for executing the above-mentioned various processes on an existing general-purpose computer, workstation, or the like, the design support device 100 according to the above embodiment It may function as a device corresponding to.

The method of providing such a program is arbitrary, and for example, it is stored and distributed on a computer-readable recording medium (flexible disc, CD (Compact Disc) -ROM, DVD (Digital Versaille Disc) -ROM) or the like. Alternatively, the program may be stored in a storage on a network such as the Internet and provided by downloading the program.

Further, when the above processing is executed by the division of the OS (Operating System) and the application program or the cooperation between the OS and the application program, only the application program may be stored in the recording medium or the storage. It is also possible to superimpose a program on a carrier wave and distribute it via a network. For example, the above program may be posted on a bulletin board system (Bulletin Board System: BBS) on the network, and the program may be distributed via the network. Then, by starting this program and executing it in the same manner as other application programs under the control of the OS, the above processing may be executed.
