How to do cad to part alignment

I am trying to figure out just the start to finish method to align the cad model to the actual part itself in order for the cmm to know the true parts location. Can someone help break that down for me? Brand new to CMM and where I work just now started sending us cad files to work with, any help would be greatly greatly appreciated! Thanks!

  • I agree with William.  If this part is a "one off" or low volume part, I'd say readpoint is the quickest and easiest.  If this is going to be a high volume part, and you have a repeatable setup, I'd suggest the manual alignment option.  Once the part has been aligned, if the setup is always in the same place, you could either use labels or mark the manual alignment features so the routine goes directly into DCC measurement once executed, eliminating the need for the operator to position the probe every run.
