Oh, there are a million things, such as NURBS (Non Uniform Rational B Splines), the ability to create polygons from a point structure, "soft" tools such as 3ds max's Free Form Deformation boxes, and Lightwave's sub-patch and magnet tools, Max's ability to render simple lines as if they were solids, boolean functions..... just all kinds of things, far too numerous to go into...not to mention the ability for people to write their own plugins for max and lightwave to increase functionality. Moray is cool, but check out the free Amapi above at the link in the announcements box. It's legit, and it's free, and it has alot of the functionality of some of the higher end programs.
