I was a beta tester for Rhino, and so I've been keeping a watch on it since it's start. It was a LONG time in the making. They REALLY tweaked all the bugs out in that short amount of time. The only point I'd like to make though, is that Rhino is VERY specific. It sounds good for you, Shroud; it is a NURBS modeller, but it's rendering engine isn't exactly the most powerful and it lacks some basic functions Carrara has. I can also say that my crashing has diminished quite extensively since I downloaded the patch. The welding thing works like a dream. And I know a LOT of modelers have trouble with Booleans. The faces don't line up right or whatever. Once you get used to it, you see that there are workarounds; you'll know when it'll crash. For example, you don't want to cut pretty much ANYthing from a plane. There was a post on this a while back. It only has four vertexes and so Carrara has trouble with it. Subdivide your objects beforehand and make your objects line up less perfectly and you'll have a lot less problems. Stick with Carrara, Adobe has some good plans for it, I'm sure. It may be buggy, but I don't think moreso than TrueSpace or even MAX sometimes. Hoborg
