9. TA: FOR CLARITY, STANDARD PARTS NOT SECTIONED EVEN WHEN CUTTING PLANE PASSES THROUGH THEM TA: SHAFTS, NUTS, BOLTS, RIBS, SPOKES, WEBS, LUGS RIB LUG

10. Sectioning Trade-off between Information and Clarity (features and dimensions) Projection Rules are RELAXED “supporting and fastening elements” that do not participate directly in the main machine part are NOT SECTIONED

11. Judgment to be made…
