2. Today I will be learning to : Improve my graphic skills by learning how to draw an Orthographic Projection of a 3D object All: Will be able to list the 3 Orthographic views. Most: Will be able to describe why we use guidelines Some: Will be able to evaluate why we use orthographic drawings.

3. What is an Orthographic Projection? An orthographic projection is a way of drawing a 3D object in 2D. They are used to show technical information and dimensions. They must be accurate.
