ことができる。Description: TECHNICAL FIELD The present invention relates to a shape attachment method, and more particularly to a shape attachment method for attaching a first shape to a second shape. <Conventional technology> When a CAD / CAM system is used for design work (for example, mold mold design) or drawing work, a part (for mold mold design) or a shape (for drawing creation) is converted to another part. Alternatively, it is often attached to a shape. <Problems invention is trying to solve> Meanwhile, the first shape 1 to be positioned as shown in Figure 3 as indicated by the second shape 2 in a dashed line (point P 2 to P 5 upon mounting reference), conventionally an operator, the first reference point P 1 and the second identify reference points P 2 of the shape 2, then the first and the reference point P 1 of the shape 1 second shape 2 It specifies that the reference points 2 overlap (designation of the position), and then designates the rotation angle θ of the first shape 1 (designation of the direction). Thereby, the system obtains the translation amount and the rotation angle of the first shape 1 based on the instruction of the operator, and uses the translation amount and the rotation angle to execute the parallel / rotation coordinates with respect to the first shape data. Conversion is performed, and the first shape 1 (solid line in FIG. 3) is attached to the second shape 2 as shown by a dashed line. However, in such a conventional method, when specifying a position, the exact coordinate value of the reference point of each shape cannot be easily known, or the direction of the shape (rotation angle θ) must be separately specified after specifying the position. It had to be troublesome. Accordingly, an object of the present invention is to provide a shape mounting method that can easily and accurately mount a first shape on another second shape. <Means for Solving the Problems> FIG. 1 shows a CAD / CA for realizing the shape mounting method of the present invention.
It is a block diagram of M system. 11a is a processor, 12 is a graphic display device, 14a is a keyboard, and in the graphic display device 12, a CRT is a display screen, and 1 is a first
Shape, 1a, 1b first linear element shape 1, P 1 is the first representative point shape 1, 2 second shape, 2a, 2b is second
The linear element P 2 of the second shape 2 is a positioning point of the second shape 2. <Operation> Two adjacent linear elements 1a and 1b in the first shape 1
And two adjacent linear elements 2a and 2b in the second shape 2 are specified. Thereby, the processor 11a
Represents the intersection P1 of the two linear elements 1a, 1b in the first shape 1 with the two linear elements 2a, 2b in the second shape 2.
And overlapping, the intersection P 2 of the first, first, second linear element 2a to the second linear element 1a, 1b a specified in the second shape 2, respectively designated in the first shape 1 , 2b and the first shape 1 is attached to the second shape 2. <Embodiment> FIG. 1 shows a CAD / CA for realizing the shape mounting method of the present invention.
It is a block diagram of M system. 11a is a processor, 11b is a ROM, 11c is a RAM, 12 is a graphic display device, 13 is a tablet device, 13a is a tablet surface, 13b is a menu table, 13c is a mouse, 14a is a keyboard, 14b is an XY plotter, 14c is The disk controller 15 is a large-capacity storage device that stores various data files, automatically created design data, drawing data, and the like. In the graphic display device 12, CRT is a display screen, a first shape 1 is to be positioned, 1a, 1b first linear element shape 1, P 1 is the first representative point shape 1, 2 A second shape to which the first shape 1 is attached, 2a and 2b are linear elements of the second shape 2, and P2 is a second element.
Is a positioning point of the shape 2 of FIG. FIG. 2 is a flow chart of the shape attaching process of the method of the present invention. Hereinafter, the shape attaching process will be described with reference to the flowchart of FIG. It is assumed that the shape 1 and the second shape 2 in FIG. 1 have been defined as graphics and have already been displayed on the display screen CRT. The operator designates “movement of shape” by a predetermined operation from the tablet, and picks the first shape 1 and the second shape 2 (FIG. 1) on the display screen CRT,
A positioning shape and a shape to be positioned are designated (step 101). Next, when the linear element 1a of the first shape 1 is picked, a linear element of the positioning destination overlapping the linear element 1a is queried, so that the linear element 2a of the second shape 2 is picked. Then
Picking the linear element 1b of the first shape 1 asks for the linear element of the positioning destination that overlaps the linear element 1b.
Pick a straight line element 2b of shape 2 and specify two sets of straight line elements (step 102). Processor 11a linear element 1a which is picked, 1b of the intersection angle theta 1 and the straight line element 2a, 2b of the crossing angle theta 2 performs input data check equal or the like (step 103), if there is an error on the input data (Θ 1 ≠ θ 2 etc.) and start over from the process of specifying the linear element in step 102 (step 1
04). On the other hand, if there is an error on the input data, the first shape first linear element 1a, the intersection P 1 of the 1b second shape second linear element 2a, overlaps the intersection P 2 of 2b, and linear element 1
The translation amount and the rotation angle of the first shape 1 are determined (step 105) so that a and 1b respectively overlap the linear elements 2a and 2b (see the dotted line in FIG. 1), and the translation amount and the rotation angle Then, the first shape data is subjected to a parallel transformation and rotation matrix conversion process (step 106), the execution result is drawn on the display screen CRT (step 107), and the attachment process is terminated. <Effects of the Invention> As described above, according to the present invention, two adjacent shapes in the first shape are used.
Two linear elements adjacent to each other in the second shape are specified, and the processing unit determines the intersection of the two linear elements in the first shape by the two linear elements in the second shape. The first shape is superimposed on the intersection, and the specified first and second linear elements in the first shape are superimposed on the specified first and second linear elements in the second shape, respectively. Since it is configured to be attached to the second shape, the position and direction of the positioning shape can be easily specified, and the first shape can be accurately attached to the other second shape.
