Question 1 Report

Explain three reasons why a designer produces sketches by hand at the start of a project rather than working directly in a computer aided design package. [6]

Answer Details

Hand sketches are valuable at the start of a project because this stage is about generating and improving possibilities, not fixing a final design.

  1. A sketch is quick to produce, so a designer can generate and compare many alternatives before spending time developing one idea. [2]
  2. A sketch can be deliberately approximate. The designer can record an idea before exact dimensions are known, whereas a CAD model usually requires dimensions or other precise input. [2]
  3. A rough sketch signals that the idea is open to change, encouraging feedback. A highly finished CAD image can make people think that the decision has already been made and discourage criticism. [2]

A further acceptable reason is that sketching with a client or colleague lets the idea change during the discussion. The key distinction is that early sketching supports rapid exploration; CAD is more useful once the design needs precision and development. [6]
