DI:15. DRAFTING
Ȧã§ãX§ãDrafting was previously a set of techniques (using compasses, angles, T-squares, etc.) for creating drawings that could be understood and used in manufacturing.
More recently drafting is focusing less on techniques and more on conventions, because of CAD systems.
The conventions of drafting are very important because they allow us to define parts in a way that they will be understood by any engineer, machinist, technologist, etc.
