I have to believe this is doable, but my knowledge and internet searching is failing me, so I’m hoping someone here has done this and can help.
I’ve designed a relatively complicated box in Fusion 360 and have successfully used the Colorific post processor documented here:
to create all of my tool paths for the cutting of the parts. (Pictures will come eventually when things are assembled.)
The next step was to cut some adhesive backed felt for the inside of some of the parts of the box and I’m stuck on how to create the right tool path since everything I try really wants to select the face of a body and doesn’t really handle the idea of the paths of the intersection of bodies.
A simple example with a test box:
Now the easy toolpaths to create were the bodies, like:
But I want to create the path that doesn’t have the fingers hidden by the other bodies (remove the parts outside the red line and cut the red line instead instead):
In the contour selection part of the toolpath creation, I can select the intersected edges, but I can’t combine them with the rest of the body path without getting all of it (a union of both red and blue paths).
Now, obviously, I could relatively easily do post-processing work in Inkscape on the path from the body to cut off the fingers and will likely do that if I can’t figure this out, but given the number of parts that is going to be a bit error-prone so I’d rather have Fusion do all the tedious work. (The other thought I’ve had is to just add the felt as a component of the model, sketch and extrude all the pieces, and then create the paths, but again, I was hoping for something simpler.)
