For my research, I am working on Midsurface Algorithms. As a natural choice I am looking at Sheet Metal parts. I am planning to study Sheet Metal features in current CAD systems to get their ontology-taxonomy-definitions.
Are some/many Sheet Metal features derived from basic Solid Modeling features like Extrude/Revolve etc. Is there any formal material showing this map?
As you know, many complex CAD parts are simplified-idealized-defeatured before taking them to CAE. Can you suggest any good reference on defeaturing of Sheet Metal models?
