Q.6

A ruled surface is one that may be generated by sweeping a generatrix along a path.

  • True
  • False
Q.7

The principle reason for using an auxiliary view is ________.

  • to eliminate hidden lines
  • to create a true projection plane from an inclined plane in one of the primary views

  • True
  • False
Q.18

The center line of a hidden cylinder feature appearing in the front view should line up with the center mark in the corresponding circle which appears in the auxiliary view.

  • True
