Unbridgeable gap between evolution of blueprint codes and communication – paradigm changing in production

The traditional 2D drawing (hand drawing) in engine ering has a commonly known communication code. Thes e communication codes (type of line, width of line or other marks) makes the engineering communication easier, faster and s fer. In the last couple of decades new computer aided design and manufacturing methods ave been developed. The communication has been ch anged. This article aims to investigate the gap between software development an d rules of communication. Although software support has developed the communication codes and basics have not been significantly c hanged. 2D drawing code is not yet fully included i n modern 3D CAD software. Automatic 2D drawing generation from 3D computer models r sults problems, for example in sections, cuts an d break-outs. This paper shows the most common problems and makes recommendation throu g harmonisation of the communication codes.
