Draw orthographic projections
I can draw a simple orthographic projection.
Lesson details
Key learning points
- Orthographic projections are 2D drawings from different sides to show a 3D shape.
- Orthographic projections usually include front, top, and side views.
Keywords
Orthographic - represents a 3D object in 2D, where views are projected from the object's surface
Contruction lines - used to plan out and position elements of a drawing
Isometric - a 3D representation of an object where sides are drawn at 30 degrees
Common misconception
The front view is always the most detailed side of the shape being drawn.
The front view is chosen based on the most informative and clear perspective, not necessarily the most detailed one.
Being able to live model the steps involved in creating an orthographic projection will be highly benefical.
Teacher tip
Equipment
Pencils, rulers, squared and isometric paper.
