Tolerance zone type and dimensions Tolerance zone modifiers - such as features of size Datum references (if required by the GD&T Symbol) Combined, the feature control frame provides all the information you need to measure the geometric tolerance of the features of the part and determine if the...

WhileCAD modelsproduce theoretically perfect geometrical dimensions, physically produced parts can never be perfect. GD&T defines acceptable tolerance ranges for every part feature so parts will fit into assemblies and function correctly without incurring the extra costs of tighter tolerances. Well-enacted...
ASME Y 14.5 (1994/2009) Geometric Dimensioning and Tolerancing is a standard that defines how dimensions and tolerances should be used to help you communicate the details of your design. It includes several important basic requirements: • Each necessary dimension of a device shall be shown in ...
Geometric dimensioning and tolerancing, often referred to as GD&T, is a symbolic language used on engineering drawings and models to define the allowable deviation of feature geometry. The language of GD&T consists of dimensions, tolerances, symbols, definitions, rules, and conventions that can be...
GD&T focuses solely on the geometry of the product. Linear dimensions, surface roughness, threads, etc. are not part of this standard. Why Implement GD&T? We do have traditional methods of denoting dimensions and tolerances. So what is the need for geometric dimensioning and tolerancing?
dimensions and tolerances required on a drawing. In addition, by establishing datums, GD&T provides a precise method for describing a reference coordinate system that can be used during the manufacturing and inspection processes. Through application of the GD&T standardized language of symbols you ca...
