I have cylindrical shaped part with three fins around the diameter, equally spaced. See FCF:
I am taking a point on each side of each fin to determine the .079-.118 thickness, then creating a midpoint between the two points. Then I used the midpoint to do the true position, but since it is a point, I can't take advantage of the MMC. I can probably have PC-DMIS put on the thickness on the report and then calculate bonus manually and subtract that from the true position on the report. But is there a way to have PC-DMIS do this so that it can take the thickness and then calculate bonus and apply it to true position?
You need to construct three widths (one for each fin) and then use the geometric tolerance command to report position of all three of them as a pattern to datums A and C.
