Lesson details

Key learning points

  1. The crating technique can be used with isometric and perspective sketching.
  2. When using the crating technique, it is important that the vertical lines are parallel.
  3. The crating technique can be used to sketch curves and complex shapes.
  4. We can use the crating technique to help sketch existing products in 3D.

Keywords

  • Perspective - a drawing technique that creates the illusion of depth and space on a flat surface

  • Isometric - a 3D representation of an object where sides are drawn at 30 degrees

  • Crating - a technique used to draw more complex 3D shapes

  • Construction lines - used to plan out and position elements of a drawing

  • Proportion - the relationship between different sizes and how they compare to each other

Common misconception

3D sketching is just 2D sketching with an additional dimension.

To be able to sketch in 3D, we need to understand depth and perspective.
