[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a CAD system and a recording medium for managing shape data and its attribute data.
[0002]
[Prior art]
Conventionally, in the case of attaching attribute data (name, number, etc.) to shape data (symbol), a CAD system takes attribute data into shape data into one segment in consideration of high-speed automatic processing and ease of search ( It is customary to take attribute data as information in the shape data and take it as one element attribute).
[0003]
[Problems to be solved by the invention]
Conventionally, as described above, since one segment is used, (1) only the shape data is changed, (2) only the attribute data (name and number, etc.) are changed, and the editing function for (1) and (2) It is necessary to prepare editing functions for each of them individually, and to make changes using these editing functions for (1) and (2), the operability becomes complicated, and the segmentation must be disassembled. There was a problem that editing response was slow.
[0004]
Also, when converting a drawing drawn by another CAD system, segmented elements are usually decomposed into individual general elements (lines, points, characters, etc.) and lose their meaning as shape data attributes. In addition, there is a problem that it is necessary to newly attach shape data and attribute data when the data is taken into the own CAD system.
[0005]
SUMMARY OF THE INVENTION In order to solve these problems, an object of the present invention is to arrange shape data and attribute data within a predetermined range of attribute points of the shape data and associate the two with each other so that shape data and attribute data can be managed separately. And

As described above, the (1) shape data and (2) attribute data of FIG. 3 are input to create the shape data of (a) and (b) of FIG. 4 and the shape data of (3) in FIG. (Symbol) can be displayed with attribute data attached thereto, and the shape data of FIG. 4A and the attribute data of FIG. 4B can be managed independently.
[0019]
FIG. 2B shows a flowchart at the time of copying.
In FIG. 2B, S11 indicates shape data to be copied.
In step S12, a range search is performed around the attribute point. That is, for example, a search is performed to determine whether attribute data (here, “88M”) exists within a predetermined range of the attribute point a of the shape data instructed to be copied on (3) in FIG.
[0020]
A step S13 decides whether or not there is attribute data. It is determined whether the attribute data is within a predetermined range of the attribute point by the range search in S12. If YES (yes), copying is performed in S14 to S16. If NO (none), the process ends.
[0021]
In S14, since the attribute data is determined to be present in YES in S13, the attribute data is set as the copy target data.
S15 indicates the coordinates of the copy destination.
[0022]
In step S16, the shape data and the attribute data are copied. That is, the designated shape data and the attribute data within a predetermined range of the attribute point of the shape data are copied together at the designated position.
[0023]
In S17, it is determined whether or not it is the end. If YES, the process ends. If NO, the process returns to S11 and repeats.
As described above, in response to the shape data to be copied and the instruction of the copy destination, when the attribute data is within a predetermined range of the attribute point of the shape data to be copied, the attribute data is copied to the copy destination together with the shape data. Even if the shape data shown in FIG. 4A and the attribute data shown in FIG. 4B are managed independently, they can be linked and copied together at the time of copying.
[0024]
FIG. 2C shows a flowchart at the time of attribute movement.
In FIG. 2C, S21 designates attribute data (TEXT).
In step S22, an attribute point is searched from the attribute data. This is done, for example, by searching for the attribute point of the shape data within the predetermined range of the attribute data instructed to move the attribute on (3) in FIG. Search if attribute point a exists).
[0025]
A step S23 decides whether or not there is an attribute point. It is determined whether or not there is an attribute point by the search in S22. If YES (Yes), the movement is performed in S24 to S26. If NO (none), the process ends.
[0026]
In S24, since the attribute point is determined to be present in YES in S23, the attribute point is set as a movement target.
S25 indicates the coordinates of the destination.
[0027]
In step S26, attribute data and attribute points are moved. This moves the designated attribute data and the attribute points of the shape data within a predetermined range of the attribute data together to the designated position.
[0028]
In S27, it is determined whether or not it is the end. If YES, the process ends. If NO, the process returns to S21 and repeats.
By the above, when there is an attribute point of the shape data within a predetermined range of the attribute data to be moved, in accordance with the attribute data to be moved and the instruction of the destination, by moving to the destination together with the attribute data, Even if the attribute data of FIG. 4B and the shape data of FIG. 4A are managed independently, it is possible to move them together in association with the movement.
