Symetricity tolerance
WebAll figures in this International Standard for the 2D drawing indications have been drawn in first-angle projection with dimensions and tolerances in millimetres. It should be understood that third-angle projection and other units of measurement could have been used equally well without prejudice to the principles established. WebIn GD&T, symmetry tolerance establishes a tolerance zone for the median points of non-cylindrical part features.This tolerance is similar to concentricity, and the verification of symmetry tolerence is likewise time …
