The GD&T symmetry callout ensures symmetry control by checking the distance between any two corresponding points on either side of the datum. We know that point O divides segment GD in two parts, but we don't know if it's an equal division to say GO = OD, we don't enough information to say that. Flatness and surface profile lie in two different fundamentals of GD&T (out of a total of four) namely, flatness is categorized as “form”, while the surface profile is categorized as a feature of “profile”. 20+ Geometry.

If you mean partially overlapping, then tests would have to be made with various points (vertices) on one face with the bounding box of the other face, and then vice versa as well. It can be used on nearly all kinds of complex outer shapes where other tolerances are not easily applicable. . 4 billion, 1. This control requires that every point on the surface must lie within a tolerance range that mimics the surface profile. While it. The GD&T symbols are a quick and effective way of communicating complex information that would otherwise fill a design diagram with text clutter. ”. Profile of a line is a 2-Dimensional tolerance range that can be applied to any linear tolerance. The example from Y14.
