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. WebSymmetry tolerance in GD&T creates a 3-dimensional geometric tolerance zone with respect to the datum plane. It controls how much the points between two features may deviate from a specified center plane or axis. It can only be applied to non circular features. Symmetry tolerance is similar to concentricity.
