Say if I were to design a part, which comprises of:
* solids that are made by CNC, 3D printing or casting;
* sheetmetal processed by lasercutting, waterjet cutting or photo etching followed by folding; and
* soldering and/or welding of the above parts together to form the finished part
then an assembly of parts by loose, transitional or interference fit.
For solids, obviously I will start with Parts and PartDesign workbenches.
However, for sheetmetal where I design the needed parts, then place the parts onto a sheet for lasercutting or photoetching to get optimal placements, and to simulate folding of the cut parts before assembly, what are the best tools?
Also, in the case of photoetching, one of the common way to easily get folding right is to half-etch along the line to be folded, if the edge radius is so small that it is close to the thickness of the sheetmetal. Then when the part is folded, it tends to fold along that line.
So what is the best workflow to design such an assembly? If we can do this well, then FreeCAD can be a great tool to design kits for model locomotives
