Geometric Dimensioning & Tolerancing
Geometric dimensioning and tolerancing refers to the specific standardized symbols used throughout engineering drawings to communicate the precise part design and functional intention. The most recent iteration, ASME Y14.5 Dimensioning & Tolerancing standards, is the most authoritative guide for the design language of geometric dimensioning and tolerance for applications in the 21st century. This guide establishes the acceptable symbols, rules, definitions, and requirements, and recommended practices for stating and interpreting dimensioning and tolerancing requirements on engineering drawings, digital models, and all related documents. Recent changes in this version help address the widespread use of CAD modeling and the reduced dependence on traditional orthographic views for product definition. Contracting Geometric Design and Technology dimensioning and tolerancing consulting services for your company can help advance blueprint designs and engineering drawings to refine tolerances and maximize product approval rates. We can assess existing plans and incorporate ASME Y14.5 geometric dimensioning and tolerancing standards throughout the design and drawing development process.
