Abstract An automated method based on the curve chain was proposed for dimensioning
of engineering drawings for the mechanical products. According to the internal relation
between the features of 3D model feature and elements of 2D drawing, the curve chain was
established to reflect the geometric topological structure between the elements. It divides
the dimensions into the absolute dimensions within the cure chain and the relative
dimensions between the curve chains. The parallel and lengthy relationship between the
drawing elements of the constructed X and Y parallel matrix was solved to remove
redundant elements in the curve chain and labeled the… More >
