Try "Rhino". You can download an evaluation copy, complete with
tutorial at Rhino.com (I think, if not I'll e-mail you a correction
tomorrow).

I've downloaded a copy myself but haven't had much time to play;it
does have both solid modeling and surfacing capability, and should be
able to do the tasks you're interested in.

If you try it and like it, it costs round $800 for the real thing,
which is dirt cheap for a CAD program with the kind of capability
you're looking for.

Good luck.
