Can a hole axis be create and recognized as T value in CAD. The part has a hole that is smaller than any probe tip I have available. I would like to be able to place probe at surface of the hole and wall and recognize the hole axis real time in T (CAD). I have 2016 CAD++ SP7. Thanks in advance.
Ah, you want to do like PolyWorks can do with the real time "Build/Inspect" mode. Sorry, I misread that.
Well, even with PolyWorks, you would still need to align to the part, but in PC-DMIS, you might have to go an extra step. (I haven't touched Portable in PC-DMIS in several years now, so I don't know if PC-DMIS has the same capability or not.)
Align to the part, auto-feature a single point circle, construct a generic point with the values from the circle, and dimension that:
