8. Conventional Representations
Simplify standard features to reduce clutter: AS 1100
- Threads – external: continuous thick for crest, continuous thin for root. Internal as in true projection.
- Knurling – indicated by note, not drawn full.
- Springs – schematic outline with centre lines.
- Bearings, gears – simplified outlines.
7. Sections & Hatching
- Cutting planes – thick chain line with arrows at ends, labelled with uppercase letters (e.g.,
A). - Hatching (section lining) – continuous thin lines at 45° (or 30°/60°) equally spaced.
- Hatching omitted for thin parts (e.g., webs, bolts) if sectioned longitudinally.
- Adjacent parts shown with hatching in different directions or spacing.
