I have a model where several solids are linked with chains. The original design contains a lot of empty space.
I am looking for software, which can automatically move the solids and fold the chains such that the total build volume gets smaller (total build volume is a major cost driver on shapeways.com). Obviously, the topology of the design must not change, i.e., it should be possible to return the model to the original state without breaking chains.
I tried Blender - Rigid Body Physics, but that has stability issues.
