1. DRAFTING• 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. 1.1 CONVENTIONAL DRAFTING1.2 NOTATIONS1.3 WORKING DRAWINGS1.4 PRACTICE PROBLEMS1.5 REFERENCES |
