Profile Tolerance

Hello All,

I have a part that the drawing only given a couple of FCF for True Position for 4 holes, Angle related to Datum A B &C and a profile tolerance of .030. I have to use a CAD model for inspection.

I was able inspecting the holes. For the remaining periphery of the parts, have been told because Profile Tolerance was given, I have to use a feature in PC-DMIS to inspect the periphery of the part, include angles. Please see the picture attached.

I am newbie to Romer Arm and PC-DMIS and working Profile Tolerance. Your guidance is greatly appreciated.

I am not seeing the profile that you are talking about. I see flatness which evaluates the form of the plane to itself but it is not relative to anything else. So unless there is a page missing there is not a profile check unless they want you to report the flatness as a profile of a surface form only. Should yield the same results but I would report the flatness as it is on the print.
