We are currently using Catia/Delmia V6 and are trying to integrate our document management and document change system. For an all Dassault product system, Enovia and Engineering Central are the obvious choice. Before diving in fully, I was curious if anyone is using any other combination of products (inside or outside of the Dassault universe) for document and change management. What kind of success have you had? Where have you found the most prevalent gaps in your systems? If you are running EC, what has been your experience with the software (ease of use, total product integration, etc.)?
