WebDec 1, 2024 · True Position – Location of a Feature = Position in terms of the axis, point or plane defines how much variation a feature can have from a specified exact true location. The position tolerance is a 2 or 3-Dimensional tolerance zone that surrounds the true location where a feature must lie. WebGD&T Flatness is a common symbol that references how flat a surface is regardless of any other datum’s or features. It comes in useful if a feature is to be defined on a drawing that needs to be uniformly flat without tightening any other dimensions on the drawing.
