• Drafting 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.
