I've been trying to split my part file into 2 parts and then assemble them back together as an assembly (the reason for this being that I need separate .stl files to print in multiple materials).
For the uploaded file, the split function would split my part into 5 separate parts instead of what I want (and have done), which is to have 3 of the sections in one file and 2 of the sections in the other.
What I've done is to use an extruded cut to remove material, then flip the cut and save it as another file, then assemble the 2 together.
It works, but any small changes would then involve multiple steps to implement, and it would be even more complicated if I wanted to do it in 3 parts if I wanted to print in 3 materials. I'm hoping someone here would be able to recommend a more elegant solution to this?
