I've been using the iterative alignment process almost exclusively since using PC-DMIS and it works really well with the type of parts I'm having to inspect. I wanted to create a 321 alignment using a read point to start the program and to avoid a manual alignment. I'm using a plane, line, point (origin) to create the alignment. I've included the code for my alignment and would appreciate any constructive advise. My work plane is X minus. I believe I have done this correctly but would appreciate the experts approval. Please pay particular attention to my alignment sequence in the program.
I also have a second question:
Is it okay to use auto features in an alignment?
Thanks
