Hello Keith,
If you want to cut the model with z=0 at the top of the part, it’s just like Mike said, place the model in Rhino with z=0 at the top of the part. It is also very easy to move the model together with toolpaths in Rhino before posting. Please let me know if you would like to change something in the Prototrak postprocessor and I will customize it for you.
