Quick and Automatic Assembling of 2D Part Drawings of Product under the PDM Environment

This paper introduces,under the PDM environment, how Automatic Assembly Module(AAM) links 2D part drawings generated by CAD into the proper position of an assembling drawing through assembly lay-out; realizes trim assembling by using border trimming in terms of covering relationship among the parts through solving 2D part drawing′s outer(inner) contour; or realizes hiding assembling through area covering so that 2D part drawings can be automatically assembled simply and quickly without destroying the part drawing′s information. Because the generated assembly drawing reflects dynamically the changes of part drawings, this method supports DFA powerfully.
