This technique is used to demonstrate clearly the operation of a technical product by showing it as if parts were cut away to reveal the internals. This leads to quite a large choice of nice drawings. I collected some of them for your pleasure. They can be gorgeous when the graphic designer is a real artist:
Single Lens Reflex (SLR) camera (Beau Daniels & Alan Daniels)
Cut-away dog (Beau Daniels)
American car (David Kimble)
Kodak DCT Canon EOS Digital SLR Camera (Kevin Husley)
Ear cutaway (Medecine net)
General Motors engine
Spitfire Mk I (Century Imaging)
How a theatre is air conditionned (Frank Soltesz, Saturday Evening Post, March 1951)
Great Wall of China (circa 1570)
Noah's Ark (David Deal)
