Design Sketching

On a clean sheet of paper, sketch your favorite design from the thumbnail sketches on a larger scale with more detail. Draw the top and side views. Make light projection lines from one view to the other to help you locate axle holes and other features of your design. Show the location of hidden details (such as the cartridge hole) by using dashed lines. Are you required to follow a set of specifications? If so, obtain the list of specs and read it. While doing so, look at your design sketch to see how each spec applies to your design. You may find it necessary to take notes or even change your design.
