I have some experience with coding my CMM, but recently I have been asked to determine the true position of a slot hole. Partially the drawing is calling out the TP for the front half of the slot hole but not the entire slot hole. I am trying to constrain the entire slot hole based on true position of 0.5. Previously we just measured the entire slot hole and created a center point but it was not accurate and gave random data. Currently I am simply measuring the front of the circle but I would like to control the entire slot hole. Pictures for reference. If there is anyway to assist me, please help me.

I don't think that callout is controlling one end of the slot, but the entire width of the slot. If you are using POSITION, you should be able to just use a single axis in the position dimension and all it will report is the deviation in that axis. DO NOT USE PERP TO C/L in the position dimension or it will use both directions.sigpic

I agree with Matthew D. Hoedeman and VinniUSMC about the width, but in this case, I don't understand why there's a "Ø" in the tolerance value...

CUT & PASTE and fill in the blanks method of making a print. The FCF is a 'thing', for position, paste it in, fill in the blanks. Like bolts & nuts are in a cad package for designing tooling. They don't make a bolt model for every individual bolt, it is a 'menu item', paste it in location.
Hey, all, it's friday !
Have a nice week-end !
