Research And Application On Drawing Paper Intelligent Creation

2D drawing is one of the important communication tools for engineers duringproduct designing and manufacturing. But there have several questions by using theactual commercial CAD systems in drawing processing: firstly, the efficiency ofdrawing is very low, and it almost occupy 50 percent of product modeling life;secondly, it is difficult to satisfy local and normal requirement; the processing ofheading, part-list and dimensioning is not convenient. And all these disadvantageslead to low efficiency of designing. According to above questions, following investigations have been done in thispaper by requirements of model project: Importing and editing the drawing's framewhich measure up to corporation's standards based on template technology;geometry information and non-geometry information are integrated with theestablishing of part information model, and title bar and part list can be createdautomatically by extracting feature information; a dimension model based on formfeature is advanced, part dimensions can be built after adjusting and distributing theinitial dimension model; and all of these improved the efficiency of drawingprocessing. Integrated with the of computer aided clamp design system, the moduleof intelligent processing drawing is implemented on UG. The module of intelligentprocessing drawing has been integrated in computer aided clamp system for CAMC(ChengDu Aircraft Manufacturing Corporation), and has got favorable effect.
