■ Noise can never enter the design process.

■ Specification can be achieved in 3D engineering drawings.

8. Explain how engineering drawing prevents optical illusions (Section 1.4).

9. A subcontractor receives a set of engineering drawings from a contractor, which give details of a complicated assembly and its various parts. They are asked to manufacture all the parts and assemble the artefact. What size do you think the drawings would be and what things would be printed as standard on each? Would any 'standard' thing be on one drawing and not on another? (Section 1.6.1.)

10. Explain why it is advantageous for an engineering design company to conform to ISO standards rather than any particular national standard.
