UNBRIDGEABLE GAP BETWEEN EVOLUTION OF BLUEPRINT CODES AND COMMUNICATION – PARADIGM CHANGING IN PRODUCTION

He traditional 2D drawing (hand drawing) in engineering has a commonly known communication code. These communication codes (type of line, width of line or other marks) makes the engineering communication easier, faster and safer. In the last couple of decades new computer aided design and manufacturing methods have been developed. The communication has been changed. This article aims to investigate the gap between software development and rules of communication. Although software support has developed the communication codes and basics have not been significantly changed. 2D drawing code is not yet fully included in modern 3D CAD software. Automatic 2D drawing generation from 3D computer models results problems, for example in sections, cuts and break-outs. This paper shows the most common problems and makes recommendation through harmonisation of the communication codes.
