Abstract
A Universal parallel ruler for use with three-dimensional drawings is disclosed which utilizes a pair of perpendicular scales individually secured to a mounting plate which is connected to a head portion. The head portion contains a plurality of preset stoppers which are angularly adjustable relative to the angular position of the respective axes of the three-dimensional drawing. Once each of the preset stoppers are angularly adjusted to their proper angular positions, clamp members secure each of the preset stoppers in position within the head portion. A locking piece is then utilized to disengage the head portion from one preset stopper allowing the head portion to be rotated to another preset stopper. Releasing the locking piece re-engages the head portion to another preset stopper and thus in alignment with another axis of the three-dimensional drawing.
