None of the following appears as a point in the elevation except

  • A.a line perpendicular to the horizontal plane
  • B.a line parallel to both principal planes
  • C.a line inclined to both principal planes
  • D.a line perpendicular to the vertical plane

Answer: D

Correct answer: a line perpendicular to the vertical plane

The elevation is the view onto the vertical plane, so a line appears there as a point only when it is perpendicular to that plane and therefore seen end on. A line perpendicular to the horizontal plane gives a point in the plan instead, and the other two are foreshortened rather than reduced to a point.
