Abstract :
An algorithm for recognizing and understanding dimensions in engineering drawings is presented. The dimensions are classified into 27 patterns and 48 subpatterns. The concept and algorithm of arrowhead-match is presented. A DFA is used to detect and recognize dimensions and rectify their rationality
