Tolerance zone modifiers features of size, projectionsAngularity controls the orientation of a surface or a feature of size at any angle, not just 0 degrees or 90 degrees The feature control frame for angularity is shown below When I teach GD&T, if I am running tight on time, I skip Perpendicularity and Parallelism and go right to AngularityIn GD&T the Angularity symbol is used to reference how one feature is oriented to another at a referenced angle For example, it could reference the orientation of a surface plane relative to a datum plane in a 3D tolerance zone, or it could referene the relationship of a 2D line to another 2D element Note that Angularity only indirectly controls the tolerance for the actual angle, which will normally be directly controlled by a plus/minus tolerance Mfgt 124 Solid Design In Manufacturing Gd T Ppt Download Angularity feature control frame
