Orthographic projection – from a 3D object to three views

Design & TechnologyEngineering Drawing & DesignAges 13–14

An object (a box, a wedge, an L-shaped block, a cylinder, or a hexagonal prism) rotates by mouse or touch; three orthographic views are drawn automatically and placed using first-angle projection convention: the front view on top, the top view below the front view, and the side view to the right of the front view; hidden edges are drawn as dashed lines. Change the length, width and height and watch all three views update accordingly.
