The sectional front view, cut by cut
Last year's Q10, from scratch: what a section is (cut, remove the near half, look at what's left), the four rules, then the sectional front view built in pencil order: projectors, outline, the edges the cut reveals, and hatching. Press play, keep the sound on, and answer the two questions it stops to ask.
About four minutes, watch once (⏮ ⏭ replay a scene). It stops twice to ask for your next move. Commit to an answer before it continues. Captions are on; the full transcript is below the player.
On paper: copy the top view from the past-paper page and draw the sectional front view without looking. Then try the section practice problems. The rule to keep: hatch only the metal the plane cuts; holes stay blank; no hidden lines.
