Colin,
Have you actually imported a CAD model into MAX before? I attempted it once with an Inventor model into MAX, and found the import process to be unsatisfactory. The model consisted primarily of lofted cross-sections with splines as guide rails, and on import the guide rails were clearly visible in the visual model. There were also some graphical singularities around complex geometries which I was only able to remove with a high mesh resolution. Have you found a satisfactory work around to this? The mathematical nature of CAD has always been more appealing (to me) than visual modeling, but I've not been able to find a way make it work.[/QUOTE
John, sent a PM. I think this should be done elsewhere seeing as it's not "my" thread nor is it relevant to the SBD.
thanks.
