A complete system for the intelligent interpretation of engineering drawings

摘要

Converting paper-based engineering draw- ings into CAD model files is a tedious process. Therefore, automating the conversion of such drawings represents tremendous time and labor savings. We present a complete system which interprets such 2D paper-based engineering drawings, and outputs 3D mod- els that can be displayed as wireframes. The system per- forms the detection of dimension sets, the extraction of object lines, and the assembly of 3D objects from the ex- tracted object lines.
