I am measuring a rectangular part that is 30" by 12" by .375" thick that has one datum along one of the length sides, another along one of the width sides, and the last datum on top of the part. The part has many holes and slots called out for true position to the three datums. Could someone walk me through the process of what to do in calling out true position of these holes and slots? This would be my first time using true position, I am using a Romer arm with PC DMIS 2011. Thanks in advance.

Hello Erie Ed,
Welcome to the forum! There are people here who will try to help you. However you are asking for the impossible. I do not think anyone can adequately teach you how to do this via an internet forum. Furthermore I think trying to do so is not only foolish, but would be a disservice to you and your customer. This is complex stuff. The proper way varies a great deal based on many factors. Someone might spend a lot of time and help you for this part and then you think you have got it when the next part has crucial differences you are not aware matter, resulting in your having confidence in suspect data.
You need some training. Hexagon can provide it either at one of their facilities or at your shop. There are also some individuals who do the same as independent contractors.
Beyond that the best I can do is remind you to press the F1 key to bring up the pc-dmis help files. They are not perfect, but they do have a lot of information.
Thanks for replying. I have a number of years experience with PCDMIS,but mainly with basic alignments and lately working from Cad Models. Any help would be appreciated.
