So, we are measuring a part where the datum is the O/D, but we need to find the Parallelism of both the top and the bottom surfaces of the part in reference to the Datum. Is there a way I can add a pause in the middle of the program to prompt user to "flip part" upside down, so that I can also measure the other surface to get both parallel lines and still have my GD&T features in my report without having two seperate programs? please advise. Thanks, guys..
