Model Accuracy Issues

I modeled this part for CNC machining. The machinist programming the part is complaining that my model features are slightly off (see attached). I also suspect that their cam software is not able to resolve these slight differences and that’s one of the reasons they are having difficulties.
I’m disappointed because I was hoping they could just import and program from my model.

I’m sure this is not a Rhino issue, but any input would be appreciated.


Hi Frank -can you post the model or send it to me via private message?
