Geometric Dimensioning and Tolerancing (GD&T): Profile and Runout Tolerances

Profile tolerances are typically used on irregular surfaces where flatness and position tolerances are insufficient to describe the part requirements. Runout tolerances are typically applied to rotating parts to maintain the form and location of features with respect to their bearing surfaces. This interactive, onine course will show you how to properly apply and interpret profile tolerances for both surface and line elements, how to reference datums and apply basic dimensions to describe features, and how to use composite profile tolerances to reflect specific feature requirements.
