In our experience - we handle PROE cad datas from our development department on a daily basis - both the format and the settings at which the data gets exported are equally important.
The trouble with converting CAD datas is that many CAD formats are more like volumebased models, they dont have a "surface" as we know it in 3D meshes. Converters will try to make up a surface ontop of the CAD data, but often this results in a patchwork of disconnected polygon islands, with fluctuations in the level of detail and an irratic polygon flow What gives us the most control is to export the datas from within PRO Engineer as STL with fairly high settings, convert it to obj in Deep Exploration and then reduce the unwanted detail in SI.
