I am going to fabricate a "flat packed" or sliced model of some animals using a CNC router. I first want to hollow out the inside of the model prior to slicing it in Slicer for Fusion 3d. This will reduce the weight of the final model. For example I have a .stl file of this dolphin that I am then slicing and exporting the sliced files as .dxf files. I could offset the 2D lines in the .dxf file prior to machining, but the part numbers and dowel placement would not be optimized.
Any help would be greatly appreciated.
