Seemage seems to be a great application. If I still was working as CAD Manager I would definitely give it a test drive.
Seemage 4.0 is a revolutionary way for users of 3D CAD and enterprise systems to deliver very high productivity to desktop users who need to create any kind of product documentation or procedure using design and enterprise information. Users in marketing and sales, product support, maintenance, technical illustration and documentation are rapidly adopting Seemage to create their deliverables.
"All major 3D CAD file formats are supported." according to the press release. I wonder if Autodesk's 3D formats are supported. I could not find anything about support for Inventor's files or AutoCAD's DWG.
