I'm glad everyone's enjoying Thor's models. I wonder why he calls himself the "original moron" and his website "Moron Studios"? To my architect's eyes, his designs for aircraft and spacecraft seem strikingly original...not moronic at all.
Just today that program AC3D came up in a discussion I was having with Diego Matho at the Boston Architectural College about next fall's SketchUp classes (which I have agreed to teach again)...it's odd that Diego should have become aware of it at the same time as I did. It's my understanding that AC3D has been out there for nearly a decade, but that the developer has recently extended its capabilities. I've been reading the manual, and the clear interface with which one creates organic (subsurface-smoothed) objects from blocky faceted ones is something Google should emulate for SketchUp (assuming, that is, that Google continues developing SketchUp). AC3D also has a very nice built-in mechanism for reducing mesh object polygon count.
Incidentally, although it is available on all OS right now, on the Linux platform AC3D is about the closest thing to SketchUp, as far as I can tell. I could wish it had better snaps/inferences, but at least it has some, which makes it almost unique among the Linux-friendly modelers that I have evaluated.
