TL;DR: In this paper, a drawing apparatus for preparing perspective views is described, which includes a mechanism for adjusting the position of a straight edge to draw perspective lines having vanishing points throughout the range of from zero to infinity.
Abstract: A drawing apparatus for preparing perspective views is described herein which includes a mechanism for adjusting the position of a straight edge to draw perspective lines having vanishing points throughout the range of from zero to infinity. In addition, a combination of mechanisms is disclosed for moving the straight edge to various positions on a drawing surface to draw perspective lines having a single vanishing point.
