I am wondering if anyone has tried blender and could comment on how it compares to Rhino? There is a good comparison with other 3D tools here but Rhino is not included in the list and I don't know much about any of them except that blender uses a lot of hot keys.

I'm not sure on the actual capabilities, but for cost....it is free. The rendering capabilities are great as well. We are using the Yafray integration to blender as a guide line for advancements in IronCAD's capabilities.
