The number of principal orthographic views obtainable is

  • A.three
  • B.four
  • C.eight
  • D.six

Answer: D

Correct answer: six

An object can be viewed along each of three mutually perpendicular axes from either end, giving six principal views: front, rear, left, right, top and bottom. An auxiliary view, taken normal to an inclined face, is not among them. In practice most objects need two or three, and the rest are drawn only if they add something.
