Abstract

Perspective effects in the basic lines of a technical drawing are obtained either by means of a transparent sheet marked with lines and placed on a drawing board illuminated from behind, or by use of a drawing board provided with a pivotable rule mounted on an arm that can be moved in a vertical direction, control means being provided so that the rule will alter direction and be aligned with one "vanishing point" over the whole vertical traverse of the supporting arm.
