Engineering Design Technology

EDT @ GTC prepares students to become CAD Design technicians who contribute to the design team by transforming ideas & solutions into engineering models, drawings,and specifications using state-of-the-art tools such as AutoCAD, Solid Works, and CATIA V5.

GD&T - Resource Materials

Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on 2D engineering drawings and 3D solid models that explicitly describes nominal geometry and its allowable variation. It tells the manufacturing technicians what degree of accuracy and precision is needed on each controlled feature of the part. GD&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features.

Metrology - Resource Materials

The study of measurement is a basic requirement in any field of science and technology, most importantly in engineering and manufacturing. Since metrology is the study of measurement, it is expected to enforce, validate and verify predefined standards for traceability, accuracy, reliability, and precision.  In manufacturing, the engineering drawing (including Dimensions, Tolerances, and GD&T) is the specification for the metrology process.
