We investigate the propagation of errors through geometric transformations, such as reflections, rotations, similarity transformations, and projections, and also the scalar product of vectors. This means computing tolerance zones of points which undergo such transformations, if these points and the transformations themselves are given by toleranced input data.
Keywords: Error propagation, geometric transformation, tolerance zone.
