While developing sheet metal parts, having the ability to preivew a bend's motion would be very beneficial. If a part has a bend and a feature that must clear other features, faces etc. while being bent, having the capability to show how the face goes through its bend motion will help . Sometimes, I review inventor part's bend motion within Autocad. This involves exporting, importing, copying, modyfying and then moving parts around. A lot of time would be saved having this capability within Inventor's sheet metal part model.
Thank you,
