WebMay 11, 2024 · Datum A is a OD cylinder on the Y axis of the CMM. I have a couple of circles along the same axis of the part to check runout and pcdmis tell me that the "runout tolerances require features that are concentric with the datum reference frame" and will not create the callout for me. I tried concentricity and the same thing. WebDec 14, 2014 · Perpendicularity is a fairly common symbol that requires the referenced surface or line to be perpendicular or 90° from a datum surface or line. Perpendicularity can reference a 2D line, but more commonly it describes the orientation of one surface plane perpendicular to another datum plane. The tolerance of the perpendicularity callout ...

WebDec 10, 2024 · Measure the datum feature as a full 3D feature (plane, cylinder, cone, sphere, 3D width, and so on) instead of as a 2D or 1D feature (surface line, surface circle, 2D width, surface point, 1D width). If that is not possible, ensure that the datum feature and its surface points actually do constrain the necessary degrees of freedom.
