How to probe Z prior to a corner

I have a part that I need to probe.  The Z is from the bottom of the part, as the thickness is very important.  So I want to probe Z prior to probing the edges (corner) of the part as the part will cover the Z (top of fixture /bottom of part).  I know I can do the corner first, remove the part then probe z, but that requires to put the part back in the same X-Y postion.

Thanks

 

Probe z in the fixture, then mount your part, select probe position only, probe corner, then zero x and y.

Probe only proves and finds the corner without setting a new work offset. But will be positioned over the corner.

Thanks! I should have been able to figure that out. I went deep into a deep dark hole. Sorry, I missed the obvious. Again Thanks!
