WebMay 20, 2006 · Went back into the program and evaluated the cylinder again. I tried using datums on and off and that didn't change the "allowed" bonus tolterance. However, when I clicked off the "use axis average" to evaluate from "end to end of axis" the bonus tolerance allowance went away. The circles creating the cylinder were internal and the software ... Websecondary datums involving cylindrical features on manufactured instances of the part. In Fig. 2(b) the primary datum is the axis of a cylinder fitted to a set of points on the manufactured part that correspond to the datum feature A indicated in Fig. 2(a). In this case there is no constraint on the fitting, other than that the cylinder should
