WebApr 19, 2024 · As with other GD&T callouts, we will explain circularity’s feature control frame using the three general compartments as follows: Geometric characteristic block; Feature tolerance block; Datum block; Geometric characteristic block. This block contains the symbol for the circularity callout. Circularity is represented by a circle in this block.

WebThe Feature Control Frame is the notation to add controls to the drawing. The leftmost compartment contains the geometric characteristic. In the example above, it is a location control but it can contain any of the control symbols. The first symbol in the second compartment indicates the shape of the tolerance zone. WebSymbol used by ANSI standard. It represents “Regardless of Feature Size (RFS).”. This symbol has been removed in ASME Y14.5-2009. Indication of tangent plane (ASME only) “T” stands for “tangent plane.”. How angled a plane in contact with the surface is to the datum plane within the range of specified surface is indicated by parallelism.
