Hereinafter, modes for accessing various local databases stored in the storage unit 11 will be explained as examples.

<Device software processing>
Next, processing of the design support device 1 used in the design support system will be explained. FIG. 5 is a flowchart showing an example of member interference checking processing of the design support device 1 used in the design support system disclosed herein. The component interference check process is a process of checking the suitability of a design based on the interference between an opening opened in the horizontal plane of a building and a horizontal diagonal member installed in the building. The member interference check process, which is checked using the flowchart illustrated in FIG. 5, is a process in which an inspection hole opened in a ceiling surface is exemplified as an opening opened in a horizontal plane, and interference with a horizontal brace is checked.

The control unit 10 included in the design support device 1 executes a component interference check process by executing various programs such as a CAD program 110 and a design support program 111. The control unit 10 included in the design support device 1 executes CAD processing (step S1). The CAD processing in step S1 indicates design support processing using a CAD system. In CAD processing, the CAD information database 112 is accessed, CAD data such as CAD data stored in association with building IDs and CAD data that is a basic plan stored in advance is extracted, and content is added and added as appropriate. This is done by making changes. During the CAD process, the design support apparatus 1 executes the subsequent member interference check process, either manually by a person in charge of design or automatically by an event such as the completion of a design.

The control unit 10 accesses the component information database 113 and refers to stored contents such as type information, and determines, from the component data included in the CAD data during CAD processing, that the type information is indicated by component data that is a ceiling inspection port. An opening opened in a horizontal plane is specified as a specific opening (step S2). In step S2, the CAD data is decomposed into geometric objects such as points, line segments, and areas, and is divided into parts by referring to the part information database 113, and the type information is stored as a ceiling inspection port. This is a process of specifying a member (in the example of step S1, the area of the opening) as a target for member interference checking. Note that divisions such as rooms and bathrooms, and further divisions separated by horizontal members such as beams and lintels are classified as members indicating regions. The opening specified as the specific opening is formed in a polygonal shape such as a substantially rectangular shape.

The control unit 10 acquires the coordinates of two diagonal vertices of the specific aperture having a substantially rectangular shape (step S3), and calculates the coordinates of two vertices inscribed in the specific aperture centered on the midpoint of the coordinates of the two acquired vertices. The tangent circle is derived as a derived inscribed circle (step S4).

FIG. 6 is an explanatory diagram conceptually showing an example of member interference check processing of the design support device 1 used in the design support system disclosed herein. FIG. 6 conceptually shows the processing of steps S2 to S4. As illustrated in FIG. 6, the design support device 1 specifies a substantially rectangular specific opening O in step S2, and in step S3 coordinates P1 (X1, Y1) and the coordinates P2 (X2, Y2) of the lower right vertex. Furthermore, the design support device 1 calculates the coordinates P0 {(X1 +X2)/2, (Y1 +Y2)/2} is derived in step S4. The derived inscribed circle A1 is a circle that touches two opposing long sides of the specific opening O, and is treated as a first area A1 indicating a horizontal range regarding the specific opening O in the processing described later.

FIG. 7 is an explanatory diagram conceptually showing an example of member interference check processing of the design support device 1 used in the design support system disclosed herein. FIG. 7 shows an example of another form different from the form illustrated in FIG. 6, and shows an example in which the specific opening O has a substantially square shape. When the specific opening O has a substantially square shape, the derived inscribed circle A1 is a circle that is in contact with the four sides of the specific opening O. As illustrated in FIGS. 6 and 7, the specific opening O having a substantially rectangular shape is a concept that also includes a substantially square shape. Further, the term "substantially rectangular" refers to a shape that can be considered to be substantially rectangular, and is a concept that includes shapes such as rounded rectangles that are not rectangular in the strict sense. Furthermore, the specific aperture O can be extended to quadrangles other than rectangles and polygons other than quadrangles. For example, polygons such as a polygon in the shape of a rectangle with the corners cut off, a polygon in the shape of a rectangle with the corners cut inward, etc. can be exemplified. Note that for a specific aperture that is a modified rectangle, such as a rounded rectangle, the original rectangle is assumed, and the derived area is centered at the midpoint of the diagonal line that connects the two diagonal vertices of the assumed rectangle. Derive the tangent circle.

Returning to the flowchart of FIG. 5, the control unit 10 accesses the member information database 113, refers to stored contents such as type information, and detects a substantially rectangular area in which horizontal braces are arranged as a diagonal member arrangement area. (Step S5). In step S5, for example, from the member data included in the CAD data during CAD processing, the type information is region, and the region indicated by the member data that overlaps with the placement position of the horizontal brace is detected as the diagonal member arrangement region. It is executed as a process. Further, step S5 is executed as a process of detecting, for example, a member whose member data included in the CAD data is a horizontal brace, and detecting a horizontal range in which the detected horizontal brace is arranged as a diagonal member arrangement region. You may also do so.

The control unit 10 derives a diagonal line of the substantially rectangular diagonal material arrangement area as a derived diagonal line (step S6), and derives a range within a predetermined distance in the horizontal direction from the derived diagonal line as a derived width ( Step S7).

FIG. 8 is an explanatory diagram conceptually showing an example of member interference check processing of the design support device 1 used in the design support system disclosed herein. FIG. 8 conceptually shows the processing of steps S5 to S7. As illustrated in FIG. 8, the design support device 1 detects a substantially rectangular diagonal arrangement region S in step S5, derives a derived diagonal line D, and derives a derived width w in step S6. There is. The derived diagonal line D is a line segment that is assumed to be a horizontal brace arranged in the diagonal material arrangement area S, but since the actual horizontal brace has a constant width unlike a line segment, it interferes with the line segment. A derived width w is derived as a possible horizontal region. The derived width w is a preset value, and is set to a width that allows for a margin greater than the actual width of the horizontal brace. The horizontal range in consideration of the derived width w in the horizontal direction from the derived diagonal line D is treated as a second area A2 indicating the horizontal range related to the diagonal member arrangement area in the processing described later.

Returning to the flowchart of FIG. 5, the control unit 10 determines the interference situation in a plan view of the first area indicating the horizontal range related to the specific opening and the second area indicating the horizontal range related to the diagonal material arrangement area (step S8). The first region in step S8 is the derived inscribed circle derived in step S4, and the second region is a region divided by the derived width derived in step S7.

The control unit 10 determines the suitability of the design (appropriateness of member arrangement) based on the determination result of step S8 (step S9). If it is determined in step S8 that the first region and the second region interfere, the design support apparatus 1 determines in step S9 that the design is inappropriate and the arrangement of the member is not possible. If it is determined in step S8 that the first region and the second region do not interfere, the design support apparatus 1 determines in step S9 that the design is appropriate and the arrangement of the members is possible.

FIG. 9 is an explanatory diagram conceptually showing an example of member interference check processing of the design support device 1 used in the design support system disclosed herein. FIG. 9 conceptually shows the processing of steps S8 to S9. FIG. 9 illustrates a state in which the first area A1 and the second area A2 interfere with each other. Since the first area A1 and the second area A2 interfere with each other, the design support apparatus 1 determines in step S9 that the design is inappropriate and the arrangement of the member is not possible.

FIG. 10 is an explanatory diagram conceptually showing an example of member interference check processing of the design support device 1 used in the design support system disclosed herein. FIG. 10 conceptually shows the processing of steps S8 to S9. FIG. 9 illustrates a state in which the first area A1 and the second area A2 do not interfere. Since the first area A1 and the second area A2 do not interfere, the design support apparatus 1 determines in step S9 that the design is appropriate and the arrangement of the members is possible.

Returning to the flowchart of FIG. 5, if it is determined in step S9 that placement is not possible (step S9: NO), the control unit 10 executes prohibition processing (step S10). The prohibition process in step S10 is a process in which a comment indicating that the arrangement of the member is not possible and the check result is an error is displayed on the display section 13, and data regarding the check result is stored in the check result database 114. By displaying the comment on the display unit 13 in the prohibition process of step S10, the designer can recognize that the arrangement of the ceiling inspection port and the horizontal brace are interfering with each other. After the prohibition processing in step S10, the control unit 10 returns to step S2 and repeats the processing from step S2 onwards to specify another specific opening. If there is no other opening to be specified as the specific opening, the control unit 10 ends the member interference checking process.

FIG. 11 is an explanatory diagram showing an example of an image displayed on the display unit 13 of the design support device 1 used in the design support system disclosed herein. FIG. 11 illustrates an image including information such as comments that is output as the prohibition process in step S10 shown in the flowchart of FIG. The image illustrated in FIG. 11 includes, approximately in the center, a blueprint of the building to be subjected to component interference check processing, a ceiling inspection opening, a first area that is the inscribed circle of the ceiling inspection opening, and a diagonal member installation area. An image showing a diagonal line and a second area having the width of the diagonal line is displayed. A tab indicating the hierarchy is displayed above the image, indicating that the floor plan illustrated in FIG. 11 is of the "second floor (third floor)." On the left side of the image, various information such as content (name), attributes such as hierarchy, arrangement direction (orientation), and arrangement position (coordinates) regarding the target of the check process is displayed in a table format. The attribute table illustrated in FIG. 11 shows information regarding attributes such as that there are three levels and that the content (name) is a ceiling inspection opening. Furthermore, the XY coordinates of each member are shown below. At the bottom of the image, various information such as error code, level, hierarchy, title, comment, etc. is displayed as check result information. For example, regarding the title ``Brace check for ceiling inspection opening range'' of the layer ``3rd floor'' with the error code ``XXC1010'', information is displayed that outputs the comment ``The ceiling inspection opening and the brace are interfering with each other.'' This indicates that the level of this comment is "important". The information displayed as the check results in FIG. 11 is stored in the check result database 114.

If it is determined in step S9 that placement is possible (step S9: YES), the control unit 10 ends the checking process regarding the identified opening (step S11). After finishing the check process in step S11, the control unit 10 returns to step S2, and repeats the process from step S2 onwards to specify an arrangement object that specifies another specific opening as a target arrangement object. If there is no other opening to be specified as the specific opening, the control unit 10 ends the member interference checking process.

The member interference check process is executed as described above.

As described in detail above, the design support device 1 and the like disclosed in the present application determines the horizontal range of a specific opening opened in a horizontal plane in a building and the area where horizontal diagonal members arranged in the building are arranged. The suitability of the design is determined based on the interference situation with the horizontal range regarding the installation area. Thereby, for example, it is possible to determine the interference situation between the ceiling inspection port, which is a specific opening, and the horizontal brace, and to determine the suitability of the design.
