Autodesk should make the VIZ 2005 plugin compatible with MAX 6/7.... a lot of arch firms have MAX instead of VIZ.. .since VIZ is really cut down version of MAX, a lot of them consider this issue and hence purchase MAX. Besides, both package are almost identical so making it compatible should be a breeze. (what I don't understand is why they take time in making sure it isn't compatible with MAX in the first?!)
While I am at it, I am also hoping to see it to be a true Bi-directional link to MAX. Revit entity to MAX / VIZ should be true MAX/VIZ entity. There shouldn't geometry tessellation / triangulation errors.
