While cleaning I found an old 3d computer drawing program I forgot I had. Largely because I could never get the bloody thing to WORK. It of course won't install on my new computer since it's so old. But it got me thinking how I miss having a 3d program. I had Poser for a while but I lost the copy years ago.

So my question is this. Those of you reading this, what 3d programs do you use?

I'd like to get a simple one to help me with perspective, proportions, and to make basic 3d floor plans for the places I see in dreams. Otherwise I'm gonna have to start making clay and cardboard models. And I just don't have the sanity stats (or inventory space) for that.

I've considered reinstalling secondlife but I'd rather have something I can use offline as I have limited internet access. Plus I originally quit due to all the trolls.

EDIT: Considering http://pixologic.com/sculptris/ since it's apparently free. Anyone have any thoughts on this program?
