Specs: MacBook Pro 3,1 OS X 10.5.2 Parallels 3.0 (build 5600) Boot Camp 2.1 Windows XP SP3 DWG Trueview is a free Autodesk app to view and plot/print DWG files. I've used the 2008 version under Boot Camp and Parallels sucessfully, installed the 2009 version and it works on Boot Camp but crashes at startup under Parallels, unless I turn off the DirectX experimental shaders feature (which worked with 2008 btw), then it works but 3D becomes slow and unusable.
I should add that DWG Trueview 2009 uses the same base as AutoCAD 2009, which means that the latest version of AutoCAD won't run with 3D acceleration on, now, this is a deal breaker for many of us Parallels/Fusion users, since some of us only need these programs so we can run AutoCAD on a Mac.
