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 absolute dimensions of the remaining 
valid elements. The average minimum weight coefficient was introduced to judge the 
dependence on the relative dimensions between curve chains. Through the analysis of the 
overlap between the circular rectangular areas, including all the absolute dimensions of the 
curve chains, overlapping curve chains were merged, and their dimensions were rearranged 
to avoid the cross interference between them. The method was seamlessly integrated into 
the drafting module of product design software NX, and it developed an automated 
dimensioning system. The examples show that the system has excellent interactivity and 
robustness in the dimensioning of product engineering drawings. The dimension 
information is complete, accurate and reliable.},
