[0003] Conventionally, a skeleton figure included in a skeleton figure includes a basic skeleton figure having information about an adjacent figure such as an adjacent figure ID in attribute information, and an adjacent figure ID in attribute information.
There is a general skeleton figure which does not have information on the adjacent figure such as the skeleton figure. Since the neighboring figure information can be easily extracted from the basic skeleton figure, automatic interference processing and automatic envelope processing can be performed. However, the basic skeleton figure has the following restrictions on the arrangement position.

[0004] In other words, only one pillar can be arranged for one street intersection. Also, as shown in FIG. 5, when there are only reference cores 53, 54, 55, and 56 in the vertical and horizontal directions of the pillar 50 (the street cores 51 and 52 are reference cores for the pillar 50). is there),
The arrangement range of the column 50 is determined by the adjacent reference cores 53, 54, 55.
And the range not interfering with 56 (arrows A, B, C and D
(Range indicated by). Also, as shown in FIG.
When the basic skeleton figures such as 3 and 64 exist, the range in which the column 50 and the basic skeleton figure adjacent thereto do not interfere with each other (arrows E, F, G and H) is the arrangement range of the column 50.

[0005] Only one beam and wall can be placed between adjacent columns (or grid intersections) in horizontal and vertical directions. Also, as shown in FIG.
0 and reference cores 71 and 7 in the vertical and horizontal directions.
When there are only 2, 73 and 74, the arrangement range of the beam 70 is a range that does not interfere with the adjacent reference cores 71, 72, 73 and 74 (the range indicated by arrows P and Q). Further, as shown in FIG. 7B, when the column 71 exists adjacent to the left side of the beam 70, the range in which the beam 70 and the column 71 do not interfere with each other (the range indicated by arrows R and S). ) Is the arrangement range of the beam 70. Also, the beam 70
When the column 75 and the walls 76 and 77 exist in the vertical direction of the beam 70, the beam 70 and the column 75 and the walls 76 and 7
7 (the range indicated by arrows T and U).

[0006] Although the adjacent figure information cannot be extracted from the general skeleton figure, there is no restriction on the arrangement position, and it can be arranged at an arbitrary position. The general skeleton figure does not have the adjacent figure information in the attribute information, but has the attribute type (type of column, wall, etc.). , Walls, etc. can be used to handle figures.

[0007]

As described above, in the conventional CAD system, when a skeleton drawing is copied,
It required a lot of operation and time.

Further, since the skeleton diagram includes a basic skeleton figure and a general skeleton figure, processing of these attribute information has to be performed separately.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and has a skeleton figure having information on adjacent figures as attribute information (ie, a basic skeleton figure).
