Drawing 2: Formal drawing techniques

Assembly drawings

An assembly drawing shows how parts of a product fit together. They are often used to show how to assemble parts of model kits and flat-pack furniture.

There are two types:

  • A fitted assembly drawing shows the parts put together, and can be drawn in 2D or 3D.
  • An exploded drawing shows the parts separated, but in the correct relationship for fitting together. Exploded views are usually drawn in 3D, as illustrated.
