  Hereinafter, embodiments will be described with reference to the accompanying drawings. The basic concept of a CAD (Computer Aided Design) device, main hardware configuration, operating principle, basic control method, and the like are already known to those skilled in the art, and detailed description thereof is omitted.

The configuration of the embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment. The present invention can be implemented by hardware and software. When the program is executed by software comprising a program, various functions can be realized by installing the program constituting the software in hardware such as a computer. The program is installed in a computer or the like through a communication line or using a computer-readable recording medium.

Here, the computer-readable recording medium refers to a recording medium in which information such as data and programs is accumulated by electrical, magnetic, optical, mechanical, or chemical action and can be read from a computer. Examples of such a recording medium that can be removed from the computer include a flexible disk, a magneto-optical disk, a CD-ROM, a CD-R / W, a DVD, a DAT, and a memory card. Further, there are a hard disk, a ROM (read only memory), and the like as a recording medium fixed to the computer.

  FIG. 1 is a functional block diagram showing characteristic functions of the design support apparatus according to the embodiment of the present invention. The design support apparatus 10 according to the present embodiment includes functions of a so-called CAD apparatus. For example, the design support apparatus 10 includes an input unit 11 such as a keyboard and a pointing device such as a mouse, a storage unit 12 that stores various data, a display unit 13 such as a CRT (Cathode Ray Tube) that displays CAD data to the user, The processing unit 14 is an arithmetic processing unit.

  The pointing device is used when instructing a coupling position of a plurality of components displayed on the display means 13. In the database 15, CAD data and the like are constructed in a hierarchical manner. The storage unit 12 includes a memory that holds data read from the database 15, a hard disk, and the like. The database 15 may be built on the hard disk of the design support apparatus 10 or may be built on an external database server.

  Note that the connected component acquisition unit 16, the shape information acquisition unit 17, the projection point formation unit 18, the appropriateness determination unit 19, the plate thickness formation unit 20, and the line segment formation unit 21 are realized by a program executed by the processing unit 14. . The combined component acquisition unit 16 acquires component data from the database 15. The shape information acquisition unit 17 acquires the shape information of the component from the component data. Further, when the component data does not include the shape information of the component, the shape information acquisition unit 17 acquires the shape information of the component from the database 15. The processing unit 14 causes the display unit 13 to display the component data using the shape information. The other means will be described later in detail.

  In the present embodiment, a case where the database 15 is constructed in an external database server will be described. Hereinafter, the database 15 will be described as the database server 15.

  The database server 15 stores component data including a plurality of component codes (identification information, etc.) constituting a three-dimensional model such as a vehicle shell body, shape information (dimension information such as plate thickness) of each component, and the like. Yes. The design support apparatus 10 reads a plurality of component data from the database server 15 and stores them in the storage means 12 (work memory comprising a memory and / or a hard disk). Then, when the input position of the plurality of parts data is instructed by the input means 11, the connecting positions (x, y, z) such as rivets, bolts and other fastening positions, hitting positions, etc. at the connecting portions of the parts are stored in the storage means 12. Retained.

  The coupling position (x, y, z) is defined by a three-dimensional vehicle coordinate system with an arbitrary position of the vehicle (for example, the position of the center of gravity of the vehicle) as the origin.

  The storage unit 12 stores a combination of codes of coupling parts (parts coupled at the coupling position) at the coupling position (x, y, z). For example, link information indicating the association between the coupling position (x1, y1, z1) and the coupling components A and B is stored in the storage unit 12 (hard disk).

<Example 1>
FIG. 2 is a schematic diagram showing an example in which component data is displayed on the display means 13. FIG. 3 is a diagram for explaining the relationship between the design support apparatus 10 and the database server 15. In this embodiment, an example will be described in which component data of a ceiling portion of a vehicle is read and a coupling position is indicated.

  The processing unit 14 causes the storage unit 12 to read the component data A and the component data B from the database server 15 based on a user instruction using the input unit 11. And the memory | storage means 12 memorize | stores temporarily the component data A and the component data B showing the shape of the components used as the object of a coupling | bonding. FIG. 2 shows a state in which, after reading the part data A and the part data B, the hit point 1-3 which is a connecting portion between the part data A and the part data B is instructed by the pointing device.

  The processing unit 14 generates link information indicating the association between the hit points 1-3 and the part data B when the coupling position is instructed by the input unit 11 (corresponding to “instruction unit” of the present invention). For example, as shown in FIG. 6, for the hit point 1, from the left, (i) the hit point number (1), (ii) the hit point data (x1, y1, z1) indicating the hit point position, and (iii) the part number of the connecting part Link information including identification information (A, B) of component data is generated. For the hit points 2 and 3 as well, the processing means 14 generates link information similar to the hit point 1 and stores it in the storage means 12.

  Next, the first processing mode and the second processing mode for processing link information will be described. The first processing mode and the second processing mode are set by setting means for setting any of these modes. As the setting means, a mode switching button is displayed on the display means 13, and the mode switching button is pressed by the input means 11 such as a mouse, whereby the first processing mode and the second processing mode are switched and set. That's fine.

<First processing mode>
Next, FIG. 4 shows a display state after the part data B is deleted. When the component data indicated by the product number (identification information) of the link information is deleted from the storage unit 12 in the first processing mode, the processing unit 14 holds link information related to the deleted component data. When the component data B is deleted by a user instruction (FIG. 4), the component data B is deleted from the storage unit 12 (FIG. 5). Even if the component data B is deleted from the storage unit 12, the processing unit 14 retains the link information shown in FIG. 6 as it is.

  Here, when the part data B is read into the design support apparatus 10 again, the processing means 14 executes the process of associating the hit points 1-3 with the part B based on the link information as shown in FIGS. To do. This process will be described later in detail.

  In the first processing mode, when the component data B is deleted from the storage unit 12, the processing unit 14 holds the link information shown in FIG. 6 as it is, so that the user displays only the component data necessary for the operation. Can be displayed. As a result, visual complexity is eliminated, a work area of the storage means 12 can be secured, and a reduction in processing speed of the central processing unit can be prevented. Therefore, working efficiency can be improved.

  4 shows an example in which the association between the component data A and the hit points 1-3 is held when the component data B is deleted. However, the display means for the hit points 1-3 is shown. It is good also as a specification which is not displayed on 13.

<Second processing mode>
The processing means 14 updates the link information related to the deleted part data when the part data indicated in the link information is deleted from the storage means 12 in the second processing mode. As shown in FIGS. 2 and 3, when the hit point 1-3, the part data A, and the part data B are associated with each other, link information as shown in FIG. 10A is generated.

  When the component data B is deleted by a user instruction (FIG. 4), the component data B is deleted from the storage unit 12 (FIG. 7). When the component data B is deleted from the storage unit 12, the processing unit 14 updates the link information (FIG. 10B).

  With respect to the hit point 1, from the left, it is updated to link information comprising (i) the hit point number (1), (ii) the hit point data (x1, y1, z1), and (iii) the identification information (A) of the part data. That is, the update is a process of deleting the identification information of the deleted part data from the link information. For the hit points 2 and 3, the processing unit 14 updates the link information in the same manner as the hit point 1.

  Here, since the link information is updated when the part data B is read into the design support apparatus 10 again, the association between the hit points 1-3 and the part data B is recovered as shown in FIGS. do not do.

  In the second processing mode, when the part data B is deleted from the storage unit 12, the processing unit 14 can create link information according to the display state by updating the link information. Thereby, it can prevent creating incorrect link information. By using the second processing mode for correction at the time of confirmation of design work, work efficiency can be improved.

<Example 2>
FIG. 11 is a schematic diagram showing an example in which component data A and component data B are displayed on the display means 13. FIG. 12 is a diagram for explaining the relationship between the design support apparatus 10 and the database server 15. In this embodiment, an example will be described in which component data of a ceiling portion of a vehicle is read and a coupling position is indicated.

  The processing unit 14 causes the storage unit 12 to read the component data A and the component data B from the database server 15 based on a user instruction using the input unit 11. And the memory | storage means 12 memorize | stores temporarily the component data A and the component data B showing the shape of the components used as the object of a coupling | bonding. In FIG. 11, after reading the component data A and the component data B, the input means 11 indicates the hit point 1-3 which is a connecting portion of the component data A and the component data B, and further specifies the hit point 4-7. Indicates the state.

  The processing unit 14 generates link information indicating the association between the hit point 1-3 and the component data B when the input position is instructed by the input unit 11. For example, as shown in FIG. 13, with respect to the hit point 1, from the left, (i) hit point number (1), (ii) hit point data (x1, y1, z1), and (iii) identification information (A, B) of the part data Generate link information consisting of For the hit points 2 and 3 as well, the processing means 14 generates link information similar to the hit point 1 and stores it in the storage means 12.

  Further, the processing unit 14 generates link information indicating the association between the hit point 4-7, the component data A, and the component data C when the input position is instructed by the input unit 11. For example, as shown in FIG. 13, with respect to the hit point 4, from the left, (i) hit point number (4), (ii) hit point data (x4, y4, z4), and (iii) identification information (A, C) of the part data Generate link information consisting of As for the hit points 5-7, the processing means 14 generates link information as in the case of the hit points 4, and stores the link information in the storage means 12.

Here, as shown in FIGS. 11 and 12, the component data C is not read from the database server 15 into the storage unit 12 of the design support apparatus 10. Therefore, the processing unit 14 creates virtual part data C on the storage unit 12, generates link information indicating the association between the hit point 4-7 and the virtual part data C, and stores the link information in the storage unit 12.

  With reference to FIG. 14, a procedure for generating link information indicating the association between the hit point 4-7 and the virtual part data C will be described. FIG. 14 is a flowchart showing a procedure for associating a hit point with virtual part data. An example will be described in which a mouse is used as the input unit 11 and various icons are displayed on the display unit 13.

  The virtual part association mode is set using the mouse (S1). For example, an icon such as “Create virtual part” is displayed on the display means 13 and the virtual part association mode is set by clicking this icon with the mouse. When the virtual part association mode is set, the processing means 14 displays an icon such as “end of hitting instruction” on the display means 13.

  Next, when the user designates the hit point 4-7 on the part data A, the processing means 14 generates hit point data indicating the connecting position of the hit point 4-7 (S2).

  When the instruction for the hit point 4-7 is completed, the user clicks on the “end of hit point instruction” icon. The processing means 14 determines that “instruction has ended”, displays a dialog box on the display means 13, and prompts the user to input the part number of the connected part (S 4).

  When the user inputs the part number “C” of the connected part and clicks the OK button in the dialog box, the processing unit 14 generates part data indicating the virtual part C and associates the hit point 4-7 with the part data C. The link information shown is generated and stored in the storage means 12 (S5-S7).

<Modification>
In the above embodiment, the virtual part data is generated. However, the character string “C” may be included in the link information without generating the virtual part data. The virtual part data may be created as a data file that does not indicate the shape, or may be generated as data having a shape surrounding the hit points 4-7.

<Reading part data C>
When new part data is read into the design support apparatus 10 in a state where other part data is displayed, the work area of the memory cannot be secured sufficiently, and the processing speed of the central processing unit decreases. Therefore, as shown in FIGS. 15 and 16, it is desirable to perform an operation of newly reading the component data C from the database server 15 after deleting the component data B shown in FIG. 11. Even if the component data B is deleted, the link information related to the component data B is retained in the first processing mode of the first embodiment (FIG. 16).

  When the part data C is read from the database server 15 after the part data B is deleted, the association between the hit points 4-7 and the part data C is executed and displayed on the display means 13 (FIGS. 17 and 18). As a result, link information indicating the association between the part data that has not been read and the hit point data can be generated in advance, and the degree of freedom in design work is increased. Therefore, working efficiency can be improved.

<Example 3>
In the first embodiment, the case where the component data deleted from the storage unit 12 and the newly read component data are the same has been described. In the present embodiment, a case will be described in which the component data deleted from the storage unit 12 and the newly read component data are different.

FIG. 19A shows a state in which the component data A-1 is deleted after the link information indicating the association between the hit point data 4-7, the component data A-1 and the component data C is generated. Although the component data A-1 is not displayed on the display means 13, the shape is indicated by a dotted line for convenience of explanation. Here, the generated link information is the same as the link information shown in the dot 4-7 shown in FIG. For the part data A-1, link information is generated with the product number as "A" instead of "A-1." The link information may be generated with the product number “A-1”, but in this embodiment. An example of generating link information with the product number “A” will be described.

  In the state where the part data A-1 is deleted, as shown in FIG. 20A, the link information indicating the association between the hit point data 4-7 and the part data A is held. When the part data A-1 is read from the database server 15 again, the association between the hit point data 4-7 and the part data A-1 is executed.

  Here, FIG. 19B shows a state in which the component data A-2 is read from the database server 15 instead of the component data A-1. The component data A-2 has an opening in the left part. For example, both the component data A-1 and the component data A-2 are members used as a ceiling portion of an automobile, and the opening of the component data A-2 is an opening for attaching a sunroof member. Here, “A” is identification information indicating a ceiling member, and “−1” and “−2” are identification information indicating member variations.

  In the link information, the identification information “A” is stored as link information for the hit points 4-7. When the component data A-2 is read from the database server 15, the processing means 14 determines that the identification information “A” is included in the component data A-2, and the hit point data 4-7 and the component data A-2. The association process is executed (FIG. 20B).

  That is, the processing means 14 executes an association process between the hit point data and the read component data when at least a part of the identification information indicating the component data read when the component data is newly read is included in the link information.

<Example 4>
In the present embodiment, a description will be given of a case where the component data deleted from the storage unit 12 and the newly read component data are different for the hit points 1-3. In the present embodiment, the component data B that is not used in common for the component data A-1 and the component data A-2 will be described. The part data C described in the third embodiment is part data used in common for the part data A-1 and the part data A-2.

  FIG. 21A shows a state in which the component data A-1 is deleted after the link information indicating the association of the hit point data 1-3, the component data A-1, and the component data B is generated. Although the component data A-1 is not displayed on the display means 13, the shape is indicated by a dotted line for convenience of explanation. Here, the generated link information is the same as the link information shown in the dot 1-3 shown in FIG. For the part data A-1, link information is generated with the product number “A” instead of the product number “A-1.”

  In the state where the part data A-1 is deleted, the link information indicating the association between the hit point data 1-3 and the part data A-1 is retained. When the part data A-1 is read from the database server 15 again, the association between the hit point data 1-3 and the part data A-1 is executed.

Here, FIG. 21B shows a state in which the component data A-2 is read from the database server 15 instead of the component data A-1. The component data A-2 has an opening in the left part. For example, both the component data A-1 and the component data A-2 are members used as a ceiling portion of an automobile, and the opening of the component data A-2 is an opening for attaching a sunroof member. Here, “A” is identification information indicating a ceiling member, and “−1” and “−2” are identification information indicating member variations.

  In the link information, the identification information “A” is stored as link information for the hit points 1-3. When the component data A-2 is read from the database server 15, it is determined whether at least a part of the identification information indicating the component data A-2 is included in the link information. Then, it is determined whether or not the combination of the read component data A-2 and component data B is appropriate.

  When the processing means 14 determines that the combination of the read component data A-2 and the component data B to be combined is appropriate, the processing means 14 associates the read component data A-2 with the dot data 1-3. Execute.

  When the processing unit 14 determines that the combination of the read component data A-2 and the component data B to be combined is inappropriate, the processing unit 14 associates the read component data A-2 with the dot data 1-3. Do not execute.

<Determining whether the combination is appropriate>
Next, a method of determining using (1) the projection point and (2) plate thickness in order to determine whether or not the coupling is appropriate will be described.

<1. Judgment using projected points>
<1.1 Judgment that it is appropriate>
FIG. 23A is a cross-sectional view taken along the line DD ′ shown in FIG. A procedure for determining that the combination when the component data A-1 is read from the database server 15 while the component data B is displayed is appropriate will be described below. The connected component acquisition unit 16, the shape information acquisition unit 17, the projection point formation unit 18, the appropriateness determination unit 19, the plate thickness formation unit 20, and the line segment formation unit 21 are programs executed by the processing unit 14.

  The combined component acquisition means 16 acquires component data A-1 from the database server 15. The shape information acquisition unit 17 acquires the shape information of the component from the component data. The projection point forming unit 18 projects the coupling position (x, y, z) onto the coupling part of the component data B and the component data A-1, and forms a projection point pi. For example, the projection point forming means 18 lowers the perpendicular line L in a skewered manner from the coupling position (x2, y2, z2) to the coupling part of the component data B and the component data A-1, and the intersection of the vertical line L and each coupling part. Projection points p1 and p2 are formed (FIG. 23A).

  Based on the projection point pi formed by the projection point forming unit 18, the appropriateness determination unit 19 determines whether or not the coupling component data is appropriately coupled at the coupling position (x, y, z). When the projection point pi is formed by the projection point forming unit 18 at the coupling part of all the coupling component data at the coupling position (x, y, z), the appropriateness determining unit 19 determines that the coupling component is coupled at the coupling position. Judge that it is appropriate. For example, projection points p1 and p2 are formed at the coupling portion of the component data B and the component data A-1 at the coupling position (x2, y2, z2), respectively. Accordingly, since projection points are formed at the joints of all the joint components at the joint position, the appropriateness determining means 19 is appropriately connected to the component data B and the component data A-1 at the joint position (x2, y2, z2). It is determined that

<1.2 Judgment of inappropriateness>
FIG. 23B is a cross-sectional view taken along the line DD ′ shown in FIG. A procedure for determining that the coupling when the component data A-2 is read from the database server 15 in the state where the component data B is displayed is inappropriate will be described below.

  The combined component acquisition unit 16 acquires component data A-2 from the database server 15. The shape information acquisition unit 17 acquires the shape information of the component from the component data. The projection point forming unit 18 projects the coupling position (x, y, z) onto the coupling part of the component data B and the component data A-2, thereby forming a projection point pi. For example, the projection point forming means 18 lowers the perpendicular line L in a skewered manner from the coupling position (x2, y2, z2) to the coupling part of the component data B and the component data A-2, and at the intersection of the vertical line L and the coupling part. A projection point p1 is formed (FIG. 23B).

  Based on the projection point pi formed by the projection point forming unit 18, the appropriateness determination unit 19 determines whether or not the coupling component data is appropriately coupled at the coupling position (x, y, z). When the projection point pi is not formed by the projection point forming unit 18 at all the coupling parts of the coupling component data at the coupling position (x, y, z), the appropriateness determining unit 19 couples the coupling component at the coupling position. Is determined to be inappropriate. For example, only the projection point p1 is formed at the coupling portion of the component data B and the component data A-2 at the coupling position (x2, y2, z2). Accordingly, since projection points are not formed at the coupling portions of all the coupling components at the coupling position, the appropriateness determination unit 19 improperly combines the component data B and the component data A-2 at the coupling position (x2, y2, z2). It is determined that

  If it is determined by the appropriateness determining means 19 that the combination of the component data A-2 at the coupling position (x2, y2, z2) is inappropriate, the coupling position (x2, y2, z2), the component data A that is not coupled. -2 (part data for which a projection point is not formed) is added to the improper combination list built in the database server 15. The improper combination list is used to determine whether or not the combination is appropriate when the part data is newly read. For example, the processing unit 14 may read the improper combination list from the database server 15 before reading the component data from the database server 15 to determine whether or not the combination is appropriate.

<2. Judgment using plate thickness>
<2.1 Judgment that it is appropriate>
The plate thickness forming means 20 forms the plate thickness ti at the connecting part of the connecting component data at the connecting position (x, y, z). The plate thickness forming unit 20 forms the plate thickness ti of the coupling portion of each coupling component data based on the shape information of the coupling portion of each coupling component data acquired by the shape information acquisition unit 17. For example, the plate thickness forming means 20 forms the plate thicknesses tl and t2 at the connecting portion between the component data B and the component data A-1 at the connecting position (x2, y2, z2) (FIG. 23A).

  The line segment forming unit 21 forms a line segment Li by the plate thickness ti from the projection point pi on the connecting portion of each connecting part data formed by the projection point forming unit 18 in the plate thickness direction of the connecting portion. For example, the line segment forming means 21 draws the sheet thicknesses tl and t2 in the sheet thickness direction from the projection points p1 and p2 on the coupling part of the component data B and the component data A-1 at the coupling position (x2, y2, z2). Minutes (solid lines) L1 and L2 are formed (FIG. 23A).

  Based on the line segments L1 and L2 of the coupling portion formed by the line segment forming unit 21, the appropriateness determining unit 19 is appropriately configured to combine the component data B and the component data A-1 at the coupling position (x2, y2, z2). It is determined whether or not.

  The appropriateness determination means 19 determines that the line segments L1 and L2 do not overlap and are not separated from each other, and the combination of the component data B and the component data A-1 at the combination position (x2, y2, z2) is appropriate. judge.

<2.2 Judgment of inappropriateness>
Next, with reference to FIG. 23 (b), the appropriateness determination means 19 performs parts data B and parts data A.
A case where it is determined that the combination of -2 is inappropriate will be described.

  The plate thickness forming means 20 forms plate thicknesses tl and t3 at the connecting portion between the component data B and the component data A-2 at the connecting position (x3, y3, z3).

  The line segment forming unit 21 forms a line segment Li by the plate thickness ti from the projection point pi on the connecting portion of each connecting part data formed by the projection point forming unit 18 in the plate thickness direction of the connecting portion. For example, the line segment forming means 21 draws the sheet thicknesses tl and t3 in the sheet thickness direction from the projection points p3 and p4 on the coupling part of the component data B and the component data A-2 at the coupling position (x3, y3, z3). Minutes (solid lines) L1 and L3 are formed.

  Based on the line segments L1 and L3 of the coupling portion formed by the line segment forming unit 21, the appropriateness determination unit 19 properly combines the component data B and the component data A-2 at the coupling position (x3, y3, z3). It is determined whether or not.

  The appropriateness determination means 19 determines that the line segments L1 and L3 are separated from each other, and determines that the combination of the component data B and the component data A-2 is inappropriate. When the gap between the coupling portions of the component data B and the component data A-2 is equal to or greater than a predetermined value, the appropriateness determination unit 19 determines whether the component data B and the component data A-2 at the coupling position (x3, y3, z3). It may be determined that the coupling is inappropriate.

  Further, as shown in FIG. 23 (c), the line data L1 and L4 of the adjacent part data B and part data A-2 formed by the line segment forming unit 21 are overlapped, and the part data B and part data A are overlapped. -2 may interfere with each other (FIG. 23 (c)). In this case, the appropriateness determination means 19 determines that the combination of the component data B and the component data A-2 at the combination position (x3, y3, z3) is inappropriate. When the interference at the coupling portion between the component data B and the component data A-2 is equal to or greater than a predetermined value, the appropriateness determining unit 19 combines the component data B and the component data A-2 at the coupling position (x3, y3, z3). May be determined to be inappropriate.

  When the appropriateness determination means 19 determines that the connection at the connection position (x3, y3, z3) is not appropriate, the processing means 14 is added to the inappropriate connection list constructed in the database server 15. In the database server 15, an improper combination list of the coupling positions (x3, y3, z3) that are improper coupling and the inappropriate contents (gap, interference, etc.) is constructed. For example, in the improper combination list, a combination position (x3, y3, z3) resulting in an improper combination, and improper contents (there are gaps or interference in B and A-2) are added. The improper combination list is used to determine whether or not the combination is appropriate when the part data is newly read. For example, before reading the component data from the database server 15, the processing unit 14 may read an inappropriate combination list from the database server 15 and determine whether or not the combination is appropriate.

<Operation flow>
Next, the operation flow of the design support apparatus 10 described above will be described with reference to the flowchart shown in FIG. Here, as described with reference to FIG. 21 and FIG. 23B, the following description will be made assuming that the component data A-2 is newly read in a state where the component data B is displayed.

  FIG. 24 is a flowchart showing an operation flow of the design support apparatus 10.

  The combined component acquisition means 16 acquires component data A-2 from the database server 15 (S100).

  Next, the processing unit 14 compares the identification information A of the link information stored in the storage unit 12 with a part (A) of the identification information of the component data A-2, and is combined with the read component data A-2. The power component data B and the coupling position (x1, y1, z1 to x3, y3, z3) are specified.

  Thereafter, the shape information acquisition means 17 acquires shape information of the component data A-2 read from the database server 15 and the component data B to be combined with the component data A-2 (S120).

  Further, the projection point forming unit 18 selects the coupling position (x1, y1, z1), and projects the selected coupling position (x1, y1, z1) onto the coupling portion of each component data to form the projection point pi. (S130).

  Based on the projection point pi formed by the projection point forming unit 18, the appropriateness determination unit 19 determines whether or not the combination of the component data A-2 and the component data B at the combination position (x, y, z) is appropriate. Determine (S140).

  Specifically, when the projection point pi is formed by the projection point forming unit 18 at the combined part of all the component data at the combined position (x1, y1, z1), the appropriateness determining unit 19 determines that the combined position (x1 , Y1, z1) determines that the combination of the component data is appropriate. For example, it is determined that the combination of the component data B and the component data A-2 at the coupling position (x1, y1, z1) is appropriate. Further, when there is component data in which the projection point pi is not formed in the component data coupling portion at the coupling position (x, y, z) by the projection point forming unit 18, the appropriateness determination unit 19 determines that the coupling position (x, It is determined that the combination of component data in y, z) is not appropriate. For example, it is determined that the combination of the component data B and the component data A-2 at the coupling position (x2, y2, z2) is not appropriate.

  When it is determined by the appropriateness determination means 19 that the combination of the component data B and the component data A-1 at the connection position (x1, y1, z1) is appropriate, the process proceeds to the next (S150). Further, when it is determined by the appropriateness determining means 19 that the coupling component data is not properly coupled at the coupling position (x2, y2, z2), the coupling position (x2, y2, z2), the uncoupled component data B and the component The data A-2 is added to the improper combination list constructed in the database server 15 (S190), and the process proceeds to S170 described later.

  In the processing of S150, the plate thickness forming means 20 forms the plate thickness ti (t1, t3) at the connecting portion of the component data at the connecting position (x1, y1, z1). Further, the line segment forming unit 21 forms a line segment Li (L1, L3) by the plate thickness ti from the projection point pi on the connecting part of the component data formed by the projection point forming unit 18 in the plate thickness direction of the connecting unit. .

  Next, based on the line segment Li formed by the line segment forming unit 21, the appropriateness determining unit 19 determines whether or not the component data is properly combined at the connection position (x1, y1, z1) (S160). ). Specifically, the appropriateness determination means 19 determines whether or not the combination of the component data at the connection position is appropriate by determining whether the line segments Li of the adjacent component data are separated or overlapped. .

  When it is determined by the appropriateness determination means 19 that the component data is not properly combined at the connection position (x1, y1, z1) (L1, L3), the incorrect connection position in the inappropriate connection list held in the database server 15 (X1, y1, z1), the inappropriate content (gap, interference, etc.) is added (S200), and the process proceeds to (S170) described later.

  On the other hand, if the appropriateness determination means 19 determines that the connection of the component data at the connection position (x, y, z) is appropriate, the connection position (x1, y1, z1 to x3, y3, z3) indicated in the link information is displayed. It is determined whether or not an appropriate determination has been made for all (S170).

  On the other hand, when the appropriateness determination means 19 has not performed appropriateness determination for all of the coupling positions (x1, y1, z1 to x3, y3, z3), the process proceeds to the above-described process (S130). The above-described determination is repeated for the coupling position (x, y, z) for which the appropriateness determination has not been performed.

<Execution of association process>
When it is determined whether or not the coupling is appropriate for all the coupling positions, the processing unit 14 causes the display unit 13 to display the component data from which the dot data determined to be coupled properly is read as the dot. (S210). Note that the dot for which the association process is not executed is not displayed on the display means 13.

  As described above, the projection point pi is formed by the projection point forming unit 18 at the component data coupling portion at the coupling position, and the appropriateness determining unit 19 determines whether the component data coupling at the coupling position is appropriate based on the formed projection point pi. Determine whether or not. Further, the line segment forming unit 21 forms a line segment Li in the coupling part of the plurality of component data at the coupling position, and the appropriateness determining unit 19 performs the coupling of the coupling component at the coupling position based on the formed line segment Li. Determine whether it is appropriate. As a result, it is possible to determine whether or not to associate the newly read component data with the hit point data (joining position).
