I dont use my machine as much as id like, I’m cutting this shape out, but trying to pocket or dado a groove thru the center. Tool path keeps pocketing the inner center circle. I am not great with drawing vectors, so it may be that. Using CC.
I’m not even sure if this post is in the correct location.
Part of the problem is that the magenta indicates that the geometry is open/unjoined (indicated by being magenta) — select the open geometry and join it — if you still have difficulties, let us know what tooling you wish to use and upload your .c2d file.
