So the toolpath is displaying as a mesh instead of a solid? Sounds
like it lost track of the tool (beam, whatever) diameter you're
cutting with, or just isn't displaying it. If it's just displaying
the *path* the cutting tool is going to take, that's what you're
going to see.

Or is this something else entirely?
