Data for a 3D sheet metal part model is stored in a file. The stored data
includes features of the part and manufacturing information. When
different manufacturing processes are used, different geometry can be
created. The file can store multiple processes for manufacturing the part
and the geometry associated with each process. Thus, when manufacturing
the part, the user can view information for multiple stored processes
because all of the information is stored together. In addition, both 2D
and 3D data is stored for the part.
