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.
Yes I know how to use the single click hole. What i would like to do is what I was able to do with some previous software is hold the probe in the hole at the mating surface and the probe read or measure the hole axis in real time T(CAD). I'm not wanting to create a program or a report. Just want the look at the T value on the screen while holding the probe in the hole. Is there a way to do this? Thanks
Enable the DRO window and right click on it to display some of the options you can use. Other than that, hold the probe against the surface the hole is in and look at the smaller DRO in the lower right corner of the PC-DMIS window. Might not give you the T-value per se, though.
I hard figure what's the _value for a hole...
Something like sample hits around the hole obtained directly ?
In this case,
VinniUSMC gave the right link...

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:

OK Thanks for the replies. I had verisurf before and was able to create hole axis in CAD and was able to get real time data in build inspect mode quickly using the hole axis. It doesn't look like I will be able to do this with PC DMIS. Using PC DMIS it looks like I will have to go the extra step and measure and dimension the hole to get the info needed. Thanks again for the help.

I went through the same troubles when switching from Verisurf to PC-DMIS. Try creating an auto-circle with a single point, execute it, and pull up your DRO with Dx,Dy and nest the probe.

I don't know much about "portable in practice" with PC-DMIS (I'm a CMM person), but PC-DMIS does have a toolbar "Build&Inspect" - maybe something there can help?
