I had previously been using the free SolidWorks eDrawings to view dwg files. When using eDrawings, the layers in the dwg file are all preserved...alowing me to selectively turn them on and off. I've just recently bought 5 ProductView Pro licenses. ProductView seems to flatten everything from the dwg file into a single layer. Am I missing something ? Is there a swithc somewhere that I haven't found yet ? Any help would be appreciated.
