Manual drafting is the practice of creating drawings by 1. with pencil or ink. Lines and 2. are used for quality drawings. The advent of 3. introduced new technologies for drafting.
Types of lines: • section lines → thin, section 4. , dimensions and projections •5. lines → dense, visible outlines • dashed lines → 6. lines, hidden details • extension lines → thin, specific part to identify 7. • dimension lines → thin, with an 8. on each end, dimension of section
Drawing tools: • paper → specific format, 9. and thickness • technical 10. → steady flow of ink, uniform line width • mechanical pencils → graphite 11. , lines of constant width • drafting table → professional 12. for large sheets • set-square → lines at a right 13. (90°) • T-square → horizontal lines on a 14. • compass → inscribe arcs or 15. •16. → measure angles • templates or 17. → easy drawing • stainless steel 18. • drafting paper, erasers, sharpeners, drafting and 19. tape
