Carrara has it's fans, and it just got an update. It's a little pricey with a slow update cycle. I'd try out one of the free programs first. I used to own Carrera, Bryce, and Hexigon, but as I mentioned the update cycles were a real deterrent for buying newer versions at full price (when they come out). I generally like programs with a faster update development/patch cycle but that's my own preference. Also good instruction manuals. That's one draw back on many programs.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
