2. Description of the Related Art In a CAD system, various standard part figures having a standard shape are prepared, and a part of the standard part figure is deformed by changing its dimensions to obtain a desired shape. 2. Description of the Related Art It has been conventionally performed to input a part figure described above to simplify the figure input.

One of the conventional methods for deforming a standard part graphic is a parametric deformation method. In the parametric deformation, a standard part figure as shown in FIG. 11 is created in advance and registered as a parametric figure. For example, dimensions H, L1, L2, R, and C are determined as parameters.
Give its initial value. If a combination of parameters is known in advance, a parameter table is created.
At the time of inputting a figure, a parametric figure name is designated, and parameters H, L1, L2, R, and C are given to transform the figure into a desired part figure. Note that the parameters H, L1, L2,
For R and C, parameters for which a numerical value is not given adopt an initial value.

FIG. 2 is a block diagram showing one embodiment of a computer system which is the apparatus of the present invention. In FIG. 1, reference numeral 20 denotes a computer main body, which includes a CPU, a RAM, a ROM, and the like, and executes application software. 21 is a display for displaying menus and the like, 22 is a keyboard as an input device, 23 is a mouse as an input device, 24
Is a hard disk device as an external storage device, 25 is a printer as an output device, and these are connected to the computer main body 20.

In this embodiment, a case in which a window is provided on an outer wall will be described taking a CAD system for architectural design as an example. Here, the window data as the standard part graphic includes window detailed data shown in the detailed plan view of FIG. 3A and window fitting data shown in the detailed plan view of FIG. 3B. FIG.
The detailed window data of (A) includes a glass plate 30, a glass frame 31,
It has X and Y coordinate data constituting each of the window frames 32, and furthermore, coordinates of both ends in the X-axis direction are standard reference coordinates 33a,
33b, and source lines 34 and 35 are defined.

The window fitting data shown in FIG. 3B has finishing lines 40 and 41 for outdoor and indoor when the detailed window data is incorporated into the outer wall, and standard boundary lines 42 and 43 with the outer wall. A standard reference line 51 is formed by the standard reference coordinates 50a and 50b, and source lines 44 and 45 and snap lines 46, 47, 48 and 49 are defined. The window fitting data and the window detail data are used as window data by being superimposed as shown in FIG. 3C, and the reference coordinates 33a and 33b are used.
And 50a, 50b overlap with each other,
5 overlaps with 44 and 45, respectively. Note that the spring lines do not necessarily have to overlap.

In this embodiment, when the above-mentioned window data is specified and two input reference points are specified on the plan view of the outer wall, the standard reference coordinates 33a and 33b of the window detailed data and the standard reference coordinates 50a and 50B is deformed to match the input reference point, and as shown in FIG.
The window based on the modified window detail data and window closing data is incorporated.

FIG. 1 shows a flowchart of the main processing of the apparatus of the present invention. This process is started when a standard part graphic is designated and, for example, two input reference points indicating the input position and the size of the standard part graphic are designated on the currently displayed detailed view and external view.

In FIG. 2, in step S2 as a second deforming means, a springing process is performed using a spring line of standard part graphic data such as window detail data and window closing data. Next , in step S4 as first deformation means, a welling process using step lines of standard part graphic data such as windowing data is executed. Thereafter, in step S6, a repeat process using the repeat data of the standard part graphic data is executed.

In step S8, it is determined whether or not the drawing currently displayed on the display 21 for inputting a standard part graphic is a detailed drawing. Here, only in the case of the detailed diagram, the process proceeds to step S10. In step S10, hidden line erasure processing is performed on the currently displayed drawing, which is hidden by the standard part graphic when the standard part graphic is input to the currently displayed drawing. Thereafter, in step S11, the drawing incorporating the standard part graphic is displayed on the display 21, and the process is terminated.

FIG. 4 is a flow chart of the source processing, and FIG. 5 is a detailed view for explaining the source processing. FIG.
In step S12, a distance DIST between the standard reference coordinates 33a and 33b of the specified standard part graphic, for example, the window detail data in FIG. 5A is calculated. Next, in step S14, the number N of the source lines 34 and 35 intersecting with the straight line connecting the standard reference coordinates 33a and 33b is obtained.

Next, in step S16, the length DIST of the input reference line 58 connecting the two input reference points 56 and 57 specified on the outer wall 55 shown in FIG.
Ask for 2. Thereafter, in step S18, the standard reference coordinates 3
Source amount Va (Va = DIST2-DIST1) / N of each source line 34, 35 required to superimpose 3a, 33b on input reference points 55, 56, respectively.
Ask for.

Furthermore, since each source line is sourced on both the left and right sides, the odd-numbered source is on the left and the even-numbered source is on the right, so the source amount Vb (Vb = Vb = Va / 2) is obtained in step S20.
Next, in step S22, the number i is set to 1 and the process proceeds to step S24. In step S24, it is determined whether or not the number i is 2N or more. If i <2N, the process proceeds to step S26 to determine whether i is an even number. If i is an odd number, in step S28, each end point of the window detailed data located to the left from the (i + 1) / 2-th source line counted from the reference coordinates on the left is moved by Vb to the left on the X-axis, and this source The extension of the source of each line that intersects at the line position is performed.
As a result, when i = 1, each end point indicated by a black circle to the left of the spring line 34 is shifted to the left by Vb as shown in FIG.
When i = 3, as shown in FIG. 5E, each end point indicated by a black circle to the left of the
b is moved.

On the other hand, if i is an even number, in step S30 each end point of the window detail data on the right from the i / 2th source line counted from the reference coordinates on the left is moved by Vb to the right on the X-axis. Then, the source of each line intersecting at this source line position is extended. Thus, when i = 2, FIG.
As shown in (D), each end point indicated by a black circle to the left of the spring line 34 is moved to the left by Vb. When i = 4, as shown in FIG. Each end point indicated by a black circle is moved rightward by Vb, and as a result, FIG.
Window detailed data as a standard part graphic transformed as shown in (G) is obtained.

In this source processing, each line segment is sourced and extended uniformly in the horizontal direction in the source line, so that the standard part figure is deformed while maintaining the entire shape, and by setting a plurality of source lines, Adjacent spring line 3
For example, the shape (width) of the glass frame 31 between 4 and 35 can be preserved.

Note that the windowing data is also subjected to the well-out process. FIG. 6 is a flowchart of the snap process, and FIG. 7 is a detailed diagram for explaining the snap process. In FIG. 6, in step S40, a snap line 46 is created for the specified standard part graphic data, for example, the windowed data shown in FIG.
Search for ~ 49. Next, each of the step lines 46 to 49 searched in step S42 is classified into an A region on the upper side in the Y direction and a B region on the lower side in the Y direction with the standard reference line 51 as a boundary. Number of snap lines COUN
T (1) and the number COUNT of snap lines in the B area
(2) is counted.

Next, in step S44, the snap lines are sorted in the A and B regions, respectively, in the order closest to the standard reference line 51. In step S46, the variable I is set to 1, and the flow advances to step S48. When the variable I is 1, the area A is shown, and when it is 2, the area B is shown. In step S48, it is determined whether I ≦ 2. If I ≦ 2, the process proceeds to step S50, and for the outer wall 55 shown in FIG. 7B as arrangement data for arranging and inputting the figure of the part, when I = 1, the A area above the input reference line 58 in the Y direction When I = 2, a line segment parallel to the input reference line 58 is searched for in the B region on the lower side in the Y direction to be a snapped line, and the number KB of the line is counted. Next, in step S52, the snapped lines are sorted in the order close to the input reference line 58.

Thereafter, 1 is set to a variable N representing the number of the snap line sorted in step S54, and
The variable J indicating the number of the snapped line that has been sorted is set to 1, and in step S56, whether the variable N is equal to or less than the number of snap lines CONUT (I) using the variable I as a subscript,
Alternatively, it is determined whether or not the variable J is equal to or less than the number KB of snapped lines.

If this condition is satisfied, the process proceeds to step S58, where the distance M between the Nth snap line and the Jth snapped line is set.
Ask for. Then, in step S60, all the segments outside the N-th snap line of the window fitting data, which is the standard part graphic (the side farther from the input reference line 51), are moved by M in the Y direction to change the N-th snap line. Align with the J-th snapped line. Next, in step S62, each of the variables N and J is incremented by 1, and the process proceeds to step S56.

As a result, in the state where I = 1, N = 1 and J = 1, the snap line 4 of the windowed data shown in FIG.
Each line segment above 6 is moved upward and snap lines 4
6 is matched with the snapped line 60. The next I = 1,
In the state of N = 2 and J = 2, each line segment above the snap line 47 of the windowed data shown in FIG. 7D is moved upward, and the snap line 47 is made to coincide with the snap line 61.

If the condition in step S56 is not satisfied, the process proceeds to step S64, in which the variable I is incremented by 1, and the process proceeds to step S48. As a result, the processing for the B area of the windowing data is started. As a result, in the state where I = 2, N = 1 and J = 1, FIG.
Each line segment below the snap line 48 of the windowing data shown in (E) is moved downward, and the snap line 48 is made to coincide with the snapped line 62. Next I = 2, N = 2
In the state of J = 2, each lower line segment is moved downward by the snap line 49 of the windowed data shown in FIG.
The snap line 49 is made to coincide with the snap line 63.

Therefore, when I = 3, and the snapping process is terminated in the determination of step S48, the windowed data is deformed in the Y direction as shown in FIG. 7 (G), and the surface is aligned with the outer wall. Defining the snap lines 46 to 47 is substantially equivalent to providing a spring line between the standard reference line 51 and each of the snap lines 46 to 47.

FIG. 8 is a flowchart of the repeat processing, and FIG. 9 is an external perspective view for explaining the repeat processing.
The window grid data as the standard part graphic shown in FIG. 9A has an input reference line 72 based on reference coordinates 70 and 71, a source surface 75 is set, and a grid 76, a pitch and a repeat are set as repeat data. Repeat reference coordinates 77 and 78 indicating the range are set. Note that, since this is an external perspective view, it is expressed as a well-exited surface 75. If this window grid data is represented in a plan view, this is expressed as a well-exited line. Similarly, a source line may be expressed as a source point in some drawings, and these are collectively referred to as a source.

By designating this standard part figure, the figure shown in FIG.
When the input reference line 58 as shown in FIG. 9B is designated, the window grid data is deformed as shown in FIG.
7, 78 also move. In this state, the repeat processing is started.

In FIG. 8, in step S70, the distance PIST between the repeat coordinates 77 and 78 after the spring-out processing is performed.
Ask for. Next, in step S72, the number of repeats N [N = (PLIST / P)-
1]. Next, in step S74, it is determined whether or not the number of repeats N is an integer.
Proceed to.

In step S76, A is obtained by dividing distance PIST by the number of repeats N, and B is obtained by dividing distance PIST by the number of repeats N + 1. Next, at step S78, the pitch P and the integer part P of the difference between A and B
A, PB [PA = ABS (PA), PB = ABS (P
-B)]. Further, it is determined whether or not PA <PB in step S80. If PA <PB, A is closer to the pitch P, so A is set to the pitch P in step S82 to update. If PA ≧ PB, B is the pitch P
In step S84, the pitch P is set and updated in B, and the number of repeats N is set and updated in N + 1.

After step S82 or S84, the process proceeds to step S86. When the number of repeats N is an integer in step S74, the process also proceeds to step S86. Step S8
In step 6, a grid 76, which is repeat data, is repeatedly created at intervals of the pitch P from the repeat reference coordinates 77 to the repeat reference coordinates 78, and the process ends.

As a result, as shown in FIG.
6 are created and displayed at equal intervals at the pitch P. The pitch P is substantially the same even if the enlargement ratio due to the spring is different. In the hidden line elimination process S10, when the window filling data shown in FIG. 7A is superimposed on the outer wall 55 of the detailed view shown in FIG. 7B, the window filling data and the outer wall 55 as shown in FIG. Line is superimposed on it and it is hard to see. For this reason, the inside of the neighboring line on the outer periphery of the windowing data is designated in advance as a hidden line processing area. As a result, of the lines constituting the outer wall 55, the portion overlapping with the window input data arranged and input is deleted, and the display as shown in FIG.

For example, as a standard part figure, FIG.
There is glass door data shown in the plan view of FIG. The glass door data is data constituting the glass plates 80 and 81, the glass frames 83 and 84, the middle rails 85 and 86, the door frame 87 and the door pocket 88, and the spring lines 90 and 91 in the X-axis direction and the Y-axis. Direction spring lines 92, 93, and 94, a repeat line 95 representing the door pocket 88, and a pitch P are defined.
97, 98 and repeat reference coordinates 99a, 99b are defined.

By inputting input reference lines in the X and Y directions on the outer wall of the plan view, a glass door as shown in FIG. 10B is arranged and input. In this way, by simply specifying the standard part figure and specifying and inputting the input reference line on the currently displayed drawing, the standard part figure is deformed and input without losing the entire shape, and the parameter is set as in the past. There is no need for inputting and the operation is simple.

In the above embodiment, the enlargement using the source line and the snap line has been described. However, the enlargement using the source line and the snap line may be reduced. In this case, the suction is performed using the source line. The present invention is not limited to CAD for buildings, but is suitably applied to other fields such as machines, and is not limited to the above-described embodiment.
