The design development diagram of the product created by the graphic creation / editing device 2 is stored in the storage device 14. An example of a specific design development diagram of the product 30 is shown in FIG. Further, the graphic creation / editing apparatus 2 does not necessarily need to be connected to this apparatus. For example, the design development drawing of the product created by the graphic creating / editing apparatus 2 is stored in a storage medium such as a floppy disk and the storage thereof is performed. The storage shape calculation device 1 may be read through a medium.

Next, the operation of the storage shape calculating apparatus according to the first embodiment described above will be described with reference to the flowchart of FIG. First, in accordance with an instruction input from the input device 11, the design development view of the product created by the graphic creation / editing device 2 and stored in the storage device 14 is read by the design development view reading means 100 (step 201). Then, the read design development view of the product is displayed on the display device 13, as shown in FIG. Next, a plurality of development view patterns in the registered storage shape file 101 are read by the development view pattern reading means 102 (step 20).
2). The development pattern is displayed on the display device 13 in the same manner as the design development pattern. The design development view and the development pattern that are displayed are displayed together on the display device 13 so that the shapes of the two can be compared. Next, the design development view displayed on the display device 13 is compared with the development view pattern, a development view pattern similar to the product design development view is selected, and I of the similar development view pattern is selected.
The development pattern is specified by inputting the D number from the input device 11 (step 203). Then,
The storage shape pattern corresponding to the designated developed pattern is read by the storage shape pattern reading means 102 from the registered storage shape file 101 together with the arithmetic expression and parameters (step 204). The read storage shape pattern and parameters are displayed on the display device 13.
FIG. 5 shows a display example of this storage shape pattern. In this embodiment, the surface 31 of the development pattern shown in FIG.
The surface 32 is bent inward (side 33 side) at each side 35. Here, the parameter is the minimum size of each part required to specify the storage shape pattern. In this embodiment, the widths of the surfaces 31, 32 and 33 are the parameters A,
In B and C, the height is given as a parameter D, which is given as a parameter table as shown in FIG.

The arithmetic expression to be read is an expression for generating a specific storage shape by specifying the coordinates and dimensions of the storage shape pattern based on the values after the specific values are set in the above parameters. Is. For example, as shown in FIG. 7, an expression (P1 A 0, P2 E 0, etc.) that defines the intersection coordinates of each side of the storage shape, and an expression (L1 that generates an edge based on the defined intersection coordinates). P0 P3, L2
P3 P4, etc.) For the arithmetic expression, see FIG.
As shown in, when there is another parameter required to generate a specific storage shape, there is an arithmetic expression (a in FIG. 7) for calculating the value of this parameter.

When the storage shape pattern, the arithmetic expression, and the parameters are read, next, the parameter setting means 104 sets the values of the read parameters. Parameter A
Since the values of D to D are predetermined in the design development view of the product shown in FIG. 3, the values are set for the respective parameters (step 205). The value may be set automatically by reading the value from the design development view, or may be set via the input device 11. Regarding the values of other parameters E necessary for specifying the storage shape, the values of the parameters B and C set above are substituted into the arithmetic expression for calculating E (E = B-C shown in FIG. 7). Calculated automatically. As a result, the parameter E is added to the parameter table as shown in FIG.

When the parameter values are set, next, an arithmetic process is executed based on the set values to generate a storage shape (step 206). Specifically, the parameter setting means described above uses parameter values, A = 20, B = 4.
When 0, C = 10, D = 40, and E = 30 are set, as shown in FIG. 7, a formula for defining coordinates based on parameters, for example, a formula such as P1 A 0, P2 E 0 is executed. , The intersection coordinates of the read storage shape pattern are defined. For example, as shown in FIG. 9, the intersection point coordinate P1 (2
0,0), P2 (30,0) and P3 (40,0) are defined. Regarding the formula (P0) of the coordinate definition formula to which a value is given in advance, the value is used as it is regardless of the parameter. When each intersection point coordinate is defined, next, based on the intersection point coordinate, an equation for generating an edge, for example, as shown in FIG. 7, equation L1 P0 P3 is executed to generate each edge. Here, the expression L1 P0 P3 means that the side L1 of the start point P0 and the end point P3 is generated. For example, the intersection point coordinates P0 (0, 0, defined as shown in FIG.
0) and P3 (40,0), the side L1 is generated. Then, each side is generated by another side definition formula, and the storage shape is generated.

The generated storage shape is displayed on the display device 13 as shown in FIG. 11 (step 207). Also, the generated storage shape data (P0 to P6, L1 to L6)
Is stored in the registered storage shape file 101 in association with the base design development drawing (step 208). By doing this, it can be used as new data from the next time.
