Construction of Sheet Metal Part Models

Three fundamental ways for the construction of sheet metal part models are  

Construction of walls in model space, by sketch in place. 

Creating walls by extrusion of each elementary line in a polyline. 

Creating a part model in the model space by selection of bend lines on a flat pattern. 

Contours for walls can be associatively extracted from existing solid parts. This allows for sheet metal part design in the context of the surrounding or enclosed assembly. Dimensional associativities between sheet metal and other solid part models allow easy and correct dimension-driven design changes without tedious manual re-dimensioning.
