Key concepts

3 concepts

  1. 1

    The first step in orthographic projection is to draw bounding boxes to ensure all views fit on the page.

  2. 2

    When all surfaces are normal (horizontal and vertical), draw the visible faces first, then the hidden faces.

  3. 3

    Hidden surfaces are indicated by hidden lines, which should meet at a dash where horizontal and vertical lines connect.
