If your CAD part has its z zero on the bottom, which coincides with the granite surface of the CMM, How do you take hits on that surface in DCC mode? In manual mode its simple to probe the granite around the part and call that z zero. Once you switch to DCC mode, I cant figure out a way to instruct the machine to take hits on a plane extended out from the part bottom. I have worked around this in the past by moving the z on the cad model but the part I am measuring now doesn't lend itself to that method. It is basically a large cone with no plane at the top. The part is too large to fixture on its side. Thanks in advance.
I like
lovethepirk 's suggestion of adding a model to the assembly for your plate.
Yet another option, if you're not interested in doing that. Start an auto-plane and click to select the bottom surface of the part model. Then click the 'Flip Vector' button so the plane vector matches the table vector (Z+). Then either adjust the hit parameters or click and drag each hit so it is measuring points around your part.
