GENERATOR FOR 3D SHEET METAL PART MODEL CREATED BY SHEET METAL PART FEATURE OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a method for guaranteeing generation of 2D sketches based upon a 3D sheet metal part shape created by any type of sheet metal feature operation.;SOLUTION: The method includes performing a sheet metal feature operation to create the 3D sheet metal shape. The 3D sheet metal shape has multiple flanges. Then an editable 2D sketch is created for each flange by obtaining geometric parameters of the 3D sheet metal shape and linking the parameters with the appropriate generated sketch. The constraint parameters can include line segment lengths and angles between selected adjoining two line segments of the 3D sheet metal shape.;COPYRIGHT: (C)2006,JPO&NCIPI
