Hi Burr, well the thing is that I am pretty sure that the CAM software that you use will report the same thing that MoI is using (axis aligned bounding box size), when you tell it to give you the dimensions of the shape you are going to cut.

If you'd like to try that, create a box in your CAM software, get a dimensions or size report, then rotate the at something around a 45 degree angle and get a new dimensions report.

Is it possible for you to do that experiment and tell me what the results are? I mean does it report the same bounds size for you in both cases?
