I have searched on this forum and tried everything to make my CAD import and alignment work but I am still having problems. The CAD file I am importing has both its origins and vectors oriented correctly so I don't need to re-orient them. I take four hits on the top face, two on the front face and one on the left face. I have selected these points both manually as well as directly from the CAD model. I then insert an alignment. I have tried Iterative, non-iterative, CAD = PART, and anything else that I read on this site. When I run the program, it works the first time through when I follow the prompts to manually probe the part, my alignment works and I am then able to measure an array of holes on the part. The problem occurs when I try to run the program a second time in DCC. All of the target positions in my 7 points used for alignment have changed to the part work coordinates instead of the machine work coordinates so I get an "OUT OF TOLERANCE" error since the machine appears to be looking for machine work coordinate positions. I have been working on this for about 6 hours now and have runout of ideas.
I have made a new program based on Cheesie's suggestion and it worked properly. I struggled with this because 1) I'm getting old. You can teach an old dog new tricks but they don't get it quickly. 2) I am a machinist, not a CMM guy. On a machine tool, you pick up your XYZ zero and you stay in that work coordinate until you change it, not so on the CMM, the probe position readout will change based on where you place the cursor in the program. 3) Formal training will not be an option for a while yet so we will have to struggle though. Thanks for your patience.
