Course details

Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language used in engineering drawings to precisely define the size, form, orientation, and location of features on a part. It ensures that design intent is clearly communicated between design, manufacturing, and inspection teams. By using standardized symbols (as per ASME Y14.5 / ISO standards), GD&T improves product quality, ensures interchangeability of parts, reduces manufacturing ambiguity, and minimizes rework and cost.
