BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the creation of architectural drawings using a CAD system, etc., and relates to a method and apparatus for drawing walls or beams as figures constituting a building frame.

0002

[Background Art] Conventionally, when creating architectural drawings using a CAD system, etc., the building structure configuration figures such as columns, walls, beams, etc. are stored in element units in advance in a storage device, and an operator uses these figures. The building frame diagrams were read out on the display, and the building frame diagrams were combined and edited to create an architectural framework diagram. When drawing walls and beams, the core was used as a reference. A conventional wall creation method will be described with reference to FIGS. 10 to 13. In the conventional method, it is necessary as a prerequisite that at least one horizontal or vertical core line exists and that there are two or more intersections thereof. Under these conditions, as shown in the operation flowchart of FIG. 10, wall parameters are input (#11), and then pillar 1 and pillar 2 are instructed (#12). At this time, it is possible to indicate the intersection of horizontal and vertical core lines, and if a pillar exists at this intersection, that pillar (indication pillar) can be indicated. This situation is shown in FIG. Then the wall offset (
If the movement width) is valid (#13), the offset direction is instructed (#14). In this case, the data for Column 1, Wall A, and Column 2, which have the relationship shown in Figure 13, is held such that each of Columns 1 and 2 has a pointer to Wall A as an attribute, as shown in Figure 12. , Wall A has pointers to columns 1 and 2 and a figure type (basic wall) as attributes.

0003

[Problem to be Solved by the Invention] As described above, walls and beams in architectural framework drawings are drawn based on a predetermined core, and therefore, they cannot be drawn unless a reference core exists. Therefore, conventionally, drawings have been made under constraints such as providing pillars at the intersections of cores or providing walls between intersections, and it has not been possible to create walls at arbitrary positions regardless of the pillars. The present invention solves the above-mentioned problems. It is possible to draw walls or beams as building frame components at arbitrary positions, and when the shape of one continuous wall or beam is changed, It is an object of the present invention to provide a method and device for drawing walls or beams in architectural drawings, etc., in which matching objects automatically follow and deform, and the drawing operation is facilitated.

0004

[Means for Solving the Problems] In order to achieve the above object, the invention of claim 1 is a method for drawing continuous walls or beams as building frame components in architectural drawings etc. using a computer, which comprises: or following setting beam parameters:
By specifying arbitrary positions continuously, a continuous wall or beam shape is created based on that position, and the mutual relation information to adjacent walls or beams is given as an attribute of the wall or beam. When the parameters of one wall or beam are changed, the figures of other related walls or beams connected by the mutual relation information are edited again. The invention of claim 2 is a device for drawing continuous walls or beams as building frame components in an architectural drawing or the like using a computer, and a memory for storing attributes of walls or beams as building frame components in the architectural drawing or the like. an input means for inputting data such as parameters and arrangement positions for the building frame components of the storage means, and an output means for outputting the building frame configuration figures, and the storage means includes information such as attributes of walls or beams. When mutual relationship information is provided to adjacent walls or beams, and the parameters of any one wall or beam are changed, the figure ID of other related walls or beams is changed accordingly based on the mutual relationship information. It was designed to do so.

[0005]

According to the method according to claim 1, by setting the parameters of the wall or beam and continuously specifying arbitrary positions, a continuous wall or beam figure can be created based on the position, When the parameters of any one wall or beam are changed, other related walls or beams connected by interrelated information are re-edited. According to the apparatus according to claim 2, the storage means stores, as attributes, information related to adjacent walls or beams that are related to each other,
When changing the parameters of any one wall or beam,
The graphic IDs of other related walls or beams are changed accordingly, and the graphic data is edited again and output to the output means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A CAD system according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the block configuration of a CAD system. The CAD system uses a hard disk 1 (1) in which building frame configuration figures such as architectural drawings are stored in advance.
storage means), a keyboard 2 (input means) and a mouse 3 (input means) for inputting architectural drawing creation commands and parameters of the building frame constituent figures, etc. By creating , and continuously specifying any position for walls or beams in the building frame configuration figure, you can create continuous walls or beams based on that position, and also by specifying any one parameter. A CAD main body 4 that has a function to re-edit the geometry of adjacent walls or beams when changes are made, and this CAD main body 4
It is comprised of a display 5 (output means) for displaying the processed graphic data, and a plotter 6 (output means) for outputting the same graphic data as an architectural drawing on recording paper.

The CAD main body 4 includes a CPU 7 (calculating means) that calculates the coordinate values of graphic data, a ROM 8 that stores the CAD program, and a computer that changes the parameters of any one of the continuous walls or beams. RAM9 serves as a work area for editing related wall or beam shapes.
and an interface 10 for transferring data and the like between the CAD main body 4 and the input/output device. The RAM 9 is provided with an area for a video RAM 9a, and by writing graphic data into the video RAM 9a, graphics such as architectural drawings are displayed on the display 5. The architectural drawing file stored on the hard disk 1 has a hierarchical structure in which the building frame constituent figures are elements.When the CAD program is executed, the attributes of walls or beams among the hierarchically structured frame constituent figures are stored in the RAM 9. Interrelated information (pointer) 9b to mutually adjacent walls or beams is provided.

FIG. 2 shows the operation procedure when creating a continuous wall using the above CAD system, and FIG. 3 shows the state of drawing at that time. In FIG. 2, when drawing, an operator operates a keyboard 2 and a tablet 3,
Input the wall parameters such as vertical length and width for the wall of the frame structure figure (#1), and specify the first point of your choice (#2)
, then instructs the second point (#3), and repeats in the same manner until the instruction is completed (#4). In this way, as shown in FIG. 3, a wall can be created continuously at any indicated point (indicated by an x) regardless of the presence of pillars or the like.

FIG. 4 shows how data is held in this embodiment. For continuous wall A, wall B, and wall C, wall A has a pointer to wall B as an attribute, wall B has a pointer to wall A and wall C as an attribute, and wall C has a pointer to wall B as an attribute. Has a pointer. In this way, the related walls A, B, and C are connected by mutually related information. Figure 5 shows the indicated points ■, ■, ■, ■
This is a diagram when continuous walls A, B, and C are created by giving instructions in this order. (a), (b), and (c) of FIG. 6 show the construction status of data in the memory during this creation process. As shown in the figure, various data are stored in the attribute table corresponding to walls A, B, and C of the index table. Note that in the attribute table, the edges ■, ■, ■, ■ correspond to indicated points. Also, for example, when walls A and B are created, if the constituent line segments of each wall are insufficient, the lines are extended, and if there are any remaining lines, they are deleted, and the walls are connected.

[0010] The process for changing walls based on the database constructed as described above will be explained. For example, the process of increasing the width of the wall B as shown in FIG. 7 will be explained with reference to FIG. 8 showing the procedure and FIG. 9 showing the state of change in the figure at that time. First, the constituent line segments of wall B are translated in accordance with the specified wall width (#6) (a in FIG. 9). Next, the connection state of wall B with the connection wall on the end ■ side is corrected by the following procedure (#7). First, the index of wall A is obtained from the attribute data. Since the index table has a fixed length, by multiplying this index value by a certain value,
Gets the address in the index table. Since each index table stores the address of the corresponding attribute table, the attribute data of wall A can be obtained. Second, the line segment data of wall A is obtained from the attribute data of wall A. Third, find the intersection of the line segments of wall A and the line segments of wall B (including on the extension line), and if there is not enough, extend the line, and if there is a surplus, partially delete it (b in Figure 9). ,c)
. Next, the connection state with the connection wall on the end ■ side of wall B is corrected in the same way as the correction on the end ■ side of wall B (#8) (Fig. 9
d). The constructed data is written to the video ram 9a and displayed on the display 5. In addition, it is not limited to walls,
The same applies to beams. Further, the method of drawing at an arbitrary position according to the present invention is in addition to the conventional method of creating a wall or the like based on a core, and it is possible to draw a wall using either method.

[0011]

As described above, according to the method or apparatus of the present invention, when drawing a wall or beam as a building frame component, an arbitrary position can be drawn even if there is no reference center as in the past. A wall or beam shape can be created at a specified location, and a continuous wall or beam can be created in one operation. Furthermore, since the mutual relationship information for adjacent walls or beams is provided as an attribute, if you change the parameters of any member in consecutive walls or beams, the adjacent walls or beams will be automatically edited. This will simplify the operation.
