Abstract
A method for detecting shapes that are undesirable for efficient processing and which occur from tolerance conversion by comparing a geometric relationship of shape elements obtained from shape data before tolerance conversion with a geometric relationship of the shape elements obtained from shape data after tolerance conversion. An inappropriate shape is identified when the compared geometric relationships are not the same.
