CAD DEVICE, TWO-DIMENSIONAL DRAWING PREPARATION METHOD, TWO-DIMENSIONAL DRAWING PREPARATION PROGRAM BASED ON TWO-DIMENSIONAL DRAWING PREPARATION METHOD AND PROGRAM RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON
PROBLEM TO BE SOLVED: To provide a CAD device which prepares a two-dimensional drawing capable of displaying only a specified part by a hidden line or the like for the shape of a part not directly visible from a watching direction when preparing the two-dimensional drawing for working on the basis of trigonometry from the three-dimensional graphic of the die block of a mold base prepared in a three-dimensional space.;SOLUTION: The CAD system for preparing the two-dimensional drawing on the basis of trigonometry from the three-dimensional graphic 1 of the die block comprises: a two-dimensional drawing preparation means 2 for preparing the two-dimensional drawing from the three-dimensional graphic 1; a cross section display part specifying means 3 for specifying a feature part for displaying the cross section of the die block; a specified projection plane selecting means 4 for selecting a two-dimensional plane for projecting the cross section; and a cross section drawing preparation means 5 for preparing the cross section shape.;COPYRIGHT: (C)2007,JPO&INPIT
