Abstract
2D engineering drawings contain a large amount of information embedded in them. This includes the Part geometry from at least one viewpoint, Metadata in form of text in the title block, Part dimensions, dimensional lines and legends.
Converting paper-based engineering drawings into CAD model files is a tedious process and is currently done manually. Automating the conversion process of such drawings therefore, represents a significant potential for time and labor savings.
The tool developed should have a method to take a 2D Engineering drawing image and segregates the drawing and non-drawing entities or components from the image, and then generate output in digitized format to be imported in a CAD tool. Once the drawing is digitized to a certain extent, a verification tool can help in verify components which could not be digitized or missed out during digitization and later can be manually/corrected by the Domain expert.
