I'm working in Mastercam 2020, programming a complex part using a lot of rotary/ axis substitution tool paths. It's a Horizontal machine so I'm programming in the front plane. When I backplot a toolpath, the tool comes in from the back plane, the solid model rotates 180 degrees and begins it's backplot. Basically, something is 180 degrees out. Everything is posting correctly, and the verification is correct. it's just really annoying. Has anyone else ever encountered this problem?
