GD&T and related training videos 

This video illustrates a parallelism application on an ascast box requiring post machining. GD&T training 

When RMB is applied to a geometric tolerance to multiple datum features of size to establish a single datum element(s), the datum feature simulator for each feature shall be at a fixed location and orientation relative to each other 

This GD&T Training video shows a design where the requirements are that a minimum position tolerance applies at the nominal size. As the feature of size diverges either towards LMS or MMC, the position tolerance is specified to increase from the nominal position tolerance. 

This application video explores a couple of GD&T methods to refine the orientation of two hole features for a piston connecting rod. 

GD&T Perpendicularity of Hole Application. Perpendicularity is the condition of a surface, axis, or line, which is 90 deg. from a datum plane or a datum axis. 

GD&T Cylindricity Engine Piston Bore Application. Cylindricity describes a condition of a surface of revolution in which all points of a surface are equidistant from a common axis. 

Circularity describes the condition on a surface of revolution (cylinder, cone, or sphere) where all points of the surface intersected
by any plane are... more
