I had been drafting and designing with AutoCad for many years and now for the past 9 years have been modeling and drafting in 3D primarily with Solidworks  including Finite Element Analysis in CosmosWorks.  I have had formal SolidWorks training in their sheet metal capabilities.  Previously, I have owned my own commercial sheet metal business and this software has been an enormous leap forward in offering speed and ease to the chores of sheet metal object development.

 I am also versed in AutoDesk Inventor.
