algorithmic modeling for Rhino
I looked a bit to the design, it seems best to use some pipes in order to cut BREP.
First you draw the machine paths (curves), on a plane then flow along surface if surface is not flat.
Offset, move the curves away from the surface
The curves are piped with round edges
Cut the BREP
but it didn't work well, it is better use rhino and one by one but I still have failures.
I did a lot of toolpath simulation to evaluate different shapes of mill bits. I suggest using a loop to cut the breps one by one instead of all pipes at once.
