Lesson details

Key learning points

  1. Orthographic projections are used to communicate designs accurately.
  2. Orthographic projections are to scale, show multiple views and the dimensions of the design.
  3. Orthographic projections can be used to inform manufacturing.

Keywords

  • Orthographic - represents a 3D object in 2D, where views are projected from the object's surface.

  • 3rd angle - a type of orthographic drawing

  • Construction lines - guidelines used in drawings

  • Dimensions - numerical values that specify the size

  • Scale - a ratio of full size

Common misconception

Orthographic projections are completed after manufacture.

Orthographic projections are known as a working drawing. These are sent from a designer to a manufacturer before manufacturing to enable them to manufacture the product or component.


To help you plan your year 10 design and technology lesson on: Plan manufacture using orthographic projection: papers and boards, download all teaching resources for free and adapt to suit your pupils' needs...

Being able to live model the steps involved in creating an orthographic projection will be highly benefical. Use simple building blocks with the view names written on each face to learn the beginning steps. Use squared paper and shapes with straight lines to teach students the fundamentals.
