Wasn't able to find any other threads on this software package so figured I would post my 2 cents. I did the 15 day trial and liked it enough to buy a license. The thing that pushed me over the edge was the ability to modify STL files directly. If you are a student there are some educational licenses to be had at a much lower price point. Google search for "Spaceclaim 3d print" and there are some videos showing the interface and some of the stl editing features. Overall a very decent software, I am still learning about it, so not much to add beyond it is worth a try. I will try to come back and post a full review once I hone my skills some.
