The angularity control keeps the angle of a feature with respect to the datum in check We can use it to control a 2D line, but it is more popular with keeping surfaces (3D) under control This kind of tight control keeps the angle and the surface flatness in check and is recommended for part features that mate with other parts through theAngularity Angularity tolerance symbol is shown as "∠"Angularity tolerance specifies a tolerance zone defined by two parallel plane at the specified angle other than 90 degree from a datum plane or axis within where the surface or the axis of the feature must lie1 The tolerance zone is cylindrical

Angularity symbol
Angularity symbol-GD&T Symbol Relative to Datum Yes MMC or LMC applicable Yes (Uncommon) Drawing Callout Description Angularity is the symbol that describes the specific orientation of one feature to another at a referenced angle It can reference a 2D line referenced to another 2D element, but more commonly it relates the orientation of one surface planeHow to Use Symbols First select the symbol then you can drag&drop or just copy&paste it anywhere you like AltCodes can be typed on Microsoft Operating Systems First make sure that numlock is on, Then press and hold the ALT key, While keeping ALT key pressed type the code for the symbol that you want and release the ALT key

Allowed Modifiers When the considered feature is a cylinder or a width, angularity allows a maximum material modifier to indicate the specification is at the maximum material condition (MMC) Alternatively, it allows a least material modifier to indicate the specification is at the least material condition (LMC) This means that as the unrelated mating envelope size (or unrelated minimumAngularity Describes the specific orientation of one feature to another at a referenced angle Symmetry The all inclusive symbol for surfaces profile tolerances can control the size, location, orientation or form of any surface feature RunoutWith angularity, we must always have a datum reference and a basic angle Note that this time we have both datums A and B called out in order to control the angles to both datum A and datum B The angle to datum A is explicitly called out with the 45 degree basic angle The angle to datum B is an implied basic 90 degree angle

The GD&T symbols are classified into five groups as below Check out these GD&T terms and definitions 1 Form controls Straightness a tolerance that controls the form of a line somewhere on the surface or the feature Angularity specifies a tolerance zone defined by two parallel planes at the specified angle other than 90 degrees from aThe datum translation symbol is the triangle shown in the far right box of the feature control frame above It indicates that the datum feature simulator for the F datum is free to translate Angularity requires that the surface be between two parallel planes that are 2 millimeters apart and exactly degrees from datum BGeometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances It uses a symbolic language on engineering drawings and computergenerated threedimensional solid models and its allowable variation
