Title:
The draw model creation method and a draw model creation system
Document Type and Number:
Japanese Patent JP6153457
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To create a drawing model including a surplus wall part easily and quickly after the setting of the cross sections of the surplus wall part.SOLUTION: A drawing model creation system 1 creates a drawing model of a press-molding product including a surplus wall part formed around a product part from CAD data having the product part and a die face part. The drawing model creation system 1 includes a storage device 8 that stores a plane grating, which is created with a plurality of feature points defined by individual XY-coordinates, a cross section setting unit 42 that sets a plurality of cross sections of the surplus wall part between the product part and the die face part, a coordinate calculation unit 43 that projects the plane grating on the cross sections and calculates Z-coordinates on the cross sections coinciding with the XY-coordinates of the feature points as the Z-coordinates of the feature points, and a drawing model creation unit 44 that connects the feature points having obtained the XYZ-coordinates to form into a polygon to create the drawing model.
