Question

Which standard linetype is drawn in perspective sketches to control the convergence of the parallel edges of an object?

Center lines

Hidden lines

Phantom lines

Construction lines

Answer 1

Phantom lines are the standard linetype drawn in perspective sketches to control the convergence of the parallel edges of an object. Phantom lines are usually lighter than the major linetypes and help indicate which edges are parallel when viewed in perspective. This linetype is often used to indicate where a surface may have been cut-away or hidden from view.
