About this document
Understanding Perpendicularity Tolerance by Sathya Dharan is a document available to read on EtoBox.
The document discusses perpendicularity tolerance in geometric dimensioning and tolerancing (GD&T). It defines perpendicularity as a condition where a surface, plane, or axis is at a 90 degree angle to a datum. Perpendicularity can apply to surfaces or axes. For surfaces, it controls how perpendicular two surfaces are to each other, while for axes it controls how perpendicular an axis is to a datum. The tolerance is specified using a symbol of two perpendicular lines and controls deviation from perfect perp
