QUESTION
I need to control the shape of a hole, so naturally GD&T should be applied. Based on our requirements, we are able to accept a more oval or lobed hole, but profile irregularities need to be strictly controlled as they will affect the performance.
Since Circularity controls all 3 together, is it permissible (and best practice) to define a circularity tolerance of x and also apply a profile-of-a-line tolerance, y, to ensure a smooth profile? Where y << x.

Surface finish might be more appropriate to control any sharp steps, etc.
