Plan, elevation, section

Three drawings, three questions. Mix them up and the line weight will not save you.

Plan — looking downElevation — the faceSection — vertical cut
  1. 1

    Plan

    A horizontal cut, looking down. You see wall thickness, door swings, and the route through the room. You do not see the facade.

  2. 2

    Elevation

    The outside face, viewed straight on, with no perspective. Heights are true. Nothing is cut, so you do not poche a wall.

  3. 3

    Section

    A vertical cut. What the knife passes through is filled — poche. What you see beyond the cut is lighter. The ground line is the heaviest line on the sheet.
