Geometric Dimensioning and Tolerancing (GD&T)

Welcome to Geometric Dimensioning and Tolerancing (GD&T) E-Learning Module

GD&T is a design tool. It is a symbolic language used on engineering drawing to define part geometry and communicate permissible variation. The language of GD&T consists of a set of well-defined symbols, rules, definitions and conventions. GD&T is a mathematical language that can be used to define the size, form, orientation and location of part features. Proper defining of part using GD&T provides the best conditions for consistence interpretation, proper function and cost effective manufacturing.

Geometric Dimensioning and Tolerancing (GD&T) system eliminates ambiguities in engineering drawings and brings out the designer's intent very clearly. It ensures seamless communication between design, engineering, manufacturing and quality teams across the entire organization enabling them working in a concurrent engineering environment. In the competitive industrial scenario prevailing today, proper application of GD&T system helps the companies to reduce the manufacturing and inspection costs.

In this module you will be experiencing world of GD&T with ample examples and demonstrations.
