As shown in FIG. 11, walls 105, 106, 107 and 108 corresponding to the walls 85, 86, 87 and 88 are created, and finally, as shown in FIG. 12, an opening 109 corresponding to the opening 89 is formed. Creating.

Further, conventionally, a skeleton figure included in a skeleton diagram includes a basic skeleton figure having information on 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 that does not have information about adjacent figures. Since it is possible to easily extract the adjacent figure information from the basic frame figure, automatic interference processing and automatic envelope processing can be performed. However, the basic skeleton figure has the following restrictions on the arrangement position.

That is, only one pillar can be arranged for each passage intersection. Further, as shown in FIG. 5, when only the reference cores 53, 54, 55 and 56 exist in the vertical direction and the horizontal direction of the column 50 (the cores 51 and 52 are the reference cores for the column 50). is there),
The arrangement range of the pillars 50 is the reference cores 53, 54, 55 adjacent to each other.
And ranges that do not interfere with 56 (arrows A, B, C and D
It is the range indicated by. Also, as shown in FIG. 6, columns 61 and 62 and wall 6 are adjacent to column 50.
When there are basic skeleton figures such as 3 and 64, the range (arrows E, F, G and H) in which the pillar 50 and the basic skeleton figures adjacent to the pillar 50 do not interfere with each other is the arrangement range of the pillar 50.

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

[0006] In the general frame figure, the adjacent figure information cannot be taken out, but there is no limitation on the arrangement position, and the figure can be arranged at any position. A general frame figure does not have adjacent figure information in the attribute information, but has an attribute type (type of column, wall, etc.). You can handle figures in units such as walls.

[0007]

As described above, in the conventional CAD system, in order to copy the body diagram,
It required a lot of operations and time.

Further, since the skeleton diagram includes the basic skeleton figure and the general skeleton figure, it is necessary to separately process these attribute information.

The RAM 9 is provided with an area of a video RAM 9a, and by writing graphic data in the video RAM 9a, a graphic such as an architectural drawing is displayed on the display 5. When a body diagram copy command is input from the operator via the keyboard 2 or the mouse 3, the body diagram copy flag is set in the area 9b of the RAM 9. Further, the RAM 9 is provided with an attribute information storage area 9c for storing attribute information for each frame drawing, each frame figure and each core. When the skeleton figure is a basic skeleton figure, the attribute information includes information about the adjacent figure such as the adjacent figure ID. When the skeleton figure is a general skeleton figure, the attribute information includes the adjacent figure ID. It does not include information about adjacent figures such as. Further, the RAM 9 is provided with an ID buffer area 9d for storing the IDs of the frame figures created by copying, that is, columns, beams, walls, and openings.

The architectural drawing file stored in the hard disk 1 has a hierarchical structure in which the skeleton figure is an element unit, and the skeleton figure is stored in the RAM 9 when the CAD program is executed.

The operator inputs the NO command of O.

FIG. 2 is a flow chart showing an operation example of the embodiment shown in FIG. The operation of the embodiment shown in FIG. 1 will be described below with reference to FIG. First, the operator operates the keyboard 2 or the mouse 3 to input a body diagram copy command. As a result, the body diagram copy flag is set in the storage area 9b of the RAM 9.

In this state, step S1 of FIG.
In S2 and S3, the operator operates the keyboard 2
Alternatively, the mouse 3 is operated to specify the copy method, specify the body diagram of the copy object, and specify the base point and the target point.
In response to this, the CPU 7 causes the designated copy method, the designated position of the copy target body diagram, the coordinates of the body diagram and the line center included in this copy target body diagram, and the designated base point and target point positions. Are stored in the RAM 9.

Next, in step S4, the CPU 7 creates a core as the copy destination. FIG. 3 shows a specific example of the process of step S4 of FIG. Hereinafter, referring to FIG.
The processing for creating the core as the copy destination will be described.

First, in step S21, the CPU 7
Calculates the amount of movement of the core. This is because the CPU7
The position and the positions of the designated base point and the designated target point are read out from the instructed copy object body diagram stored in the AM 9 and calculated.

Next, the CPU 7 determines the RA for each target core.
From M9, the coordinate values of the original core are obtained (step S2
3) The coordinate value of the grid to be created is set in the RAM 9 (step S24). Then, the CPU 7 checks whether or not the reference cores intersect at the copy destination (step S).
25). If they intersect (YES in step S26), the operator is inquired via the display 5 whether or not to create as a general skeleton graphic, that is, whether to include information about the adjacent graphic in the attribute information of the skeleton graphic created by copying ( Step S27). When the operator instructs via the keyboard 2 or the mouse 3 to handle as a general body figure, the CPU 7 causes the attribute information of the RAM 9 so that the attribute information of the body figure created by copying does not include information about the adjacent figure. Writing is performed in the storage area 9c.

The CPU 7 transfers the processing target to the following cores (step S28), performs the processing of steps S23 to S28, and when the processing is completed for all cores (YES in step S22), the target cores Move on to the process for the actual drawing of.

The CPU 7 first creates a copy destination core in step S30 for the actual drawing of each core. This is done by the CPU 7 obtaining the coordinates of the core as the copy destination and storing it in the RAM 9.
Next, the CPU 7 in step S31, the RAM 9
The attribute information is read from the attribute information storage area 9c of FIG. 1 to obtain the attribute of the core as the copy source, and this is stored in the attribute information storage area 9c as the attribute of the core as the copy destination (step S3).

The CPU 7 moves the processing target to the core as follows (step S33), performs the processes of steps S30 to S33, and when all the cores are processed (YES in step S29), the step of FIG. Proceed to S5. In step S5, the CPU 7 determines which copy process is selected by the operator. If parallel copy process is selected, the process of step S6 is performed. If mirror copy process is selected, step S5 is performed.
7 is performed.

FIG. 4 shows an example of the mirror copy process in step S7. The mirror copy process will be described below with reference to FIG. The CPU 7 first creates a new pillar by mirror copying for each target pillar (step S42), and stores the ID of the created pillar in the ID buffer 9d of the RAM 9 (step S44). And CPU
7 moves the processing target to the next pillar (step S44),
When the processes of steps S42 to S44 are performed and the processes are completed for all the pillars (YES in step S41),
Move on to beam and wall copying.

In beam and wall copy processing, CP
U7 first creates new beams and columns by mirror-copying each of the target beams and walls (step S4).
6) The IDs of the created beams and walls are stored in the ID buffer 9d of the RAM 9 (step S47). And CP
U7 moves the processing target to the next beam and wall (step S48), performs the processes of steps S46 to S48, and when the process is completed for all the beams and walls (YES in step S45), copies the opening. Move on to.

In the copy processing of the opening, the CPU 7
First, a new opening is created by mirror copying for each target opening (step S50), and the ID of the created opening is stored in the ID buffer 9d of the RAM 9 (step S51). Then, the CPU 7 moves the processing target to the next opening (step S52), and step S52.
When the processes of 50 to S52 are performed and the process is completed for all the openings (YES in step S49), the attributes of the created body diagram are stored in the attribute information storage area 9c of the RAM 9 (step S53).

The CPU 7 stores the processed graphic data of FIG. 2 in the video RAM 9a. As a result, the figure after the body diagram copy is displayed on the display 5. When the operator inputs a print command via the keyboard 2, the graphics stored in the video RAM 9a are
Output from the plotter 6 as a hard copy.

In the above embodiment, the CPU 7 and the ROM 8 read the attribute information storage means, and the attribute information of the body figure included in the body diagram indicated by the input means includes the information about the adjacent figure. If so, it is determined whether or not the information about the adjacent figure is included in the attribute information of the body figure to be created by copying, and the body diagram instructed by the input means is produced at the instructed position. Alternatively, dedicated hardware may be provided instead of the ROM. Further, when the attribute information storage means is read and the attribute information of the body figure included in the body diagram indicated by the input means includes information about the adjacent figure, the information about the adjacent figure is created by copying. Attribute information processing means for determining whether or not to include in the attribute information of the figure, and body diagram copy means for creating the body diagram instructed by the input means may be separately provided.

Further, the present invention can be applied to various drawings such as mechanical design drawings in addition to architectural drawings.

Further, although the mouse is used as the input means in the above-mentioned embodiment, a tablet or the like may be used instead.

As is apparent from the above description, claim 1
According to the figure processing method of No. 2, if the attribute information of the body figure included in the target body figure to be copied has information about the adjacent figure, the information about the adjacent figure becomes the attribute information of the body figure to be created at the copy position. Since it is decided whether to include it and the body diagram for copying is created at the copy position,
The attribute information is automatically processed and the copy of the body diagram is automatically created only by the operator instructing the body diagram to be copied and the copy position. Therefore, the labor of the operator can be reduced and the time can be saved.

According to the graphic processing method of the second aspect, it is checked whether or not the reference core that has already been created and the reference core of the skeleton graphic to be created intersect at the copy position.
In the case of crossing, the operator is asked to include the information on the adjacent figure because the attribute information of the figure to be created at the copy position does not include the information on the adjacent figure to inquire whether to create the figure. By instructing not to do so, the layout of the body figure created by copying becomes free, and the operator can freely create the body diagram.

According to the figure processing apparatus of claim 3, the attribute information processing means reads the attribute information storage means, and the attribute information of the body figure included in the body diagram to be copied has information about the adjacent figure. Then, it is determined whether or not the information about the adjacent figure is included in the attribute information of the body figure to be created at the copy position, and the copy creating means creates the copy target body figure at the copy position. The attribute information is automatically processed and the copy of the body diagram is automatically created only by the operator instructing the body diagram to be copied and the copy position. Therefore, the labor of the operator can be reduced and the time can be saved.
