The dimension origin symbol is used to indicate where a dimension must be measured from. . Per the standard, the pitch cylinder diameter must be used to evaluate the hole location and orientation, using centerline hole location plugs. You can also place a note with the control frame, under symbols there is a check box to place a note Moven' on, very interesting though. The Radius symbol is used when a circular feature is dimensioned using the radius length. WebA convenient guide for Geometric Dimensioning and Tolerancing (GD&T) symbols at your fingertips. The slope modifying symbol is placed with a value to indicate that this value is controlled as a slope, or a flat taper.

Is it anything like TFB (that's fantastic boss)? The purpose of a countersink is to allow a fastener, typically a flathead screw, to sit slightly below the surface of the part. Where an exception to this practice is necessary, the specific feature of the screw thread (such as MAJOR DIA or MINOR DIA) shall be stated beneath the feature control frame, or beneath or adjacent to the datum feature symbol, as applicable. To paraphrase the standard, the geometric tolerances and/or datum references apply to the pitch cylinder diameter unless otherwise specified.
