If I want to design a part that has some functional/mating surfaces (i.e. the kind of thing you would draw up in CAD) and some freeform surfaces (i.e. the kind of thing you might sculpt), what's a good workflow for that? Do the functional part first in Solidworks, export to STL, and import into Blender? Or is there a good way of doing freeform design in Solidworks?
