I am pretty happy about Creo. It is free and has a pretty strong feature set, a lot stronger that 123D Design.
It is a solid modeling program, no polygon modeling, not history based, but you can adjust a lot afterwards. You can move sections and it tries to keep all blends ect. alive. So far I have not found many limitations, besides two rail sweeps. It can even to a bit of G2 blending (by selecting continuous curvature) to make smoother fillets.
It has a bit high learning curve, but there are a lot of blender users, so that should pose no problems :lol: And it uses different meanings for words than usual, like features for subgroups, and taper for drafts.
My biggest complain is that it has the most impossible name imaginable. Impossible to remember, a disaster to find on the internet. (especially with all the other Creo programs like Creo 2.0, Creo Parametric, Creo Direct, Creo Elements/Direct, etc.)
Is anyone else using it? What are your experiences about the limitations?
Just for reference: I have prior experience with Rhino (with Grasshopper), Solid Edge, Solid Works, Pro/Engineer, Autocad, Form Z. (Professionally only with the first two)
