Explicit and Persistent Knowledge in Engineering Drawing Analysis

Domain knowledge permeates all aspects of the engineering drawing analysis process, including understanding the physical processes operating on the medium i.e., paper, the image analysis techniques, and the interpretation semantics of the structural layout and contents of the drawing. Additionally, an understanding of the broader reverse engineering context, within which the drawing analysis takes place, should be exploited. Thus as part of a wider project on the reverse engineering of legacy systems, we have developed an agent-based engineering analysis system called NDAS nonDeterministic Agent System.
