Make working drawings (60 minutes)

Week 3

Make working drawings (60 minutes)

Working drawings are guides that show us how to build a specific structure. Make a working drawing of your bridge. It should be drawn to scale and show as much detail as possible.

Each member of your team should make their own first-angle orthographic projection of the bridge, showing the front view, top view and end view.

Each of your drawings should show the measurements of the structure and the scale you have chosen. Use correct line types.

You will need the following equipment:

• 30 °, 60 ° and 90 ° set square,
• a sharp pencil, and
• masking tape to attach your drawing sheet to your drawing board.
