What is the best way to deal with botched combined STLs?
I have an STL that treats the breaklines of the shoulders as an outside layer, and thus the model becomes very fragile around these faultlines.
It does so because the components (arms and torso) were never combined properly. The STL has a lot of vertices "inside" the model.
Filling holes does not work, and I already have an overlap union enabled. Is there an easy way to fix this with blender or a free CAD software?
