Sketch generator for 3D sheet metal part models created by sheet metal part feature operations
First Claim
1. A method for guaranteeing generation of 2D sketches based upon a 3D sheet metal part shape, comprising:
- performing a sheet metal feature operation to create the 3D sheet metal shape, which has multiple flanges to be made by bending operations; and
generating a separate editable 2D sketch for each flange to facilitate editing the 3D sheet metal shape,wherein separate editable 2D sketches for each flange are generated for every type of feature operation used to create the 3D sheet metal shape, and the 3D metal sheet shape is edited base upon edits made on the separate editable 2D sketches for each flange.

Abstract
A method is provided for guaranteeing generation of 2D sketches based upon a 3D sheet metal part shape created by any type of sheet metal feature operation. The method includes performing a sheet metal feature operation to create the 3D sheet metal shape. The 3D sheet metal shape will have 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.
