Geometric dimensioning and tolerancing, GD&T for short, is a procedure to define and communicate mechanical part design intent and engineering tolerances that assist and give engineers and manufactures, precise control variations in the manufacturing process for mechanical parts and components. Also, distinctive symbols—language are used on the engineering 2D drawing prints and computer-generated 3D solid models to distinctly describe the call out geometry and its permissible variation.

GD&T processes for critical request withy functional assemblies, multi-component products, or parts with complex conformity, it is critical that all components work well together. All pertinent fits and features should be specified in a way that impacts the manufacturing process and still guaranteeing functionality. GD&T, tightening tolerances by a determining factor of two can raise the price twice over or even more, due to time and higher reject rates and tooling prices. GD&T tolerances, is the system that allows design engineers and their internal inspectors to optimize functionality throughout and help keep prices low.

From prototyping through production marketing quantities, ProtoEdge team works with all types of companies who want to enhance and accelerate GD&T components requirements for digital manufacturing processes. Dimensional tolerances reflect an approximate range of a technology’s capabilities and should be viewed only as a guide.
