Stating the scale on a drawing is necessary because

  • A.the drawing may later be reproduced at a different size
  • B.the draughtsman must record which instruments were used
  • C.the sheet size is otherwise impossible to determine
  • D.the dimensions cannot be written on the drawing itself

Answer: A

Correct answer: the drawing may later be reproduced at a different size

A drawing is photocopied, scanned, printed at another sheet size and stored on paper that moves with humidity, and each of these alters every length on it. Stating the scale records what the drawing was made at, so that a reproduction can be recognised as not being at that scale - and it is why written dimensions govern over scaled ones.
