Why to use GD & T? •Ensures Specification of Design Tolerance requirements •Ensures interchangeability of parts during assembly •Provides standardization and uniformity • Adaptation to 3D CAD modeling • Leads to high productivity, less rework and reduced cost. One of the most powerful GD&T symbols is profile of a surface. It controls a shape (which is defined by basic dimensions) by building a three-dimensional tolerance zone around it. And depending on how it relates to the datums, it can also control orientation and location. The standard for dimensioning and tolerancing was revised in Geometric Dimensioning and Tolerancing (GD&T) is a system of standardized drawing symbols that is used to reduce the uncertainty and obscurity of the desired geometric shape. The GD&T system is used internationally and is language universal, as it consists of standard. One of the most powerful GD&T symbols is profile of a surface. It controls a shape (which is defined by basic dimensions) by building a three-dimensional tolerance zone around it. And depending on how it relates to the datums, it can also control orientation and location. The first page is a summary of all the geometric control symbols that shows graphically how they apply: to surfaces or to features of size. The second is a more conventional reference guide that has a lot of useful information about each control symbol.
