My company has 2 CAD systems, legacy AutoCAD garbage and ProEngineer for 3D. Oddly, PTC has a free ActiveX control that allows you to display their filetypes in web pages, .NET, or whatever...

AutoDesk does not (as far as I know). Does anyone know of a simple, no strings attached free DWG file viewer component I can embed in a .NET project? I'm making a simple engineering management program and while showing the part or it's drawing is a nice feature and works fine for our high end CAD platform, it would be nice if I could include support for the other 20% of our parts too.

I don't care if it's .NET or COM, as long as you can view, zoom, and pan DWG files without some annoying popup or watermark stamped all over the background.
