Thanks, but seriously?
Seems to me that this is a serious flaw opening the possibility for CNC programming errors even after all of the extra work; what if a drawing has dozens of dimensions and you miss one?
Perhaps AD thinks all CNC programming will come from CAM, but there are plenty of machines out there with conversational programming requiring manual input that are used for less complex parts.
