WebPractical GD&T: Concentricity – Basic Concepts. Mathematically, concentricity is a very simple concept; the centres of two objects with a clearly defined ‘centre’ (e.g. circles or regular polygons) must be at the same location. The challenge in GD&T is that no measured form is ever a perfect circle, a perfect cylinder, etc. WebThere is some confusion in the industry regarding Symmetry and Center Lines.
