ABSTRACT:
The Right Perspective Drawing Tool invention consist of a typical tape measure with a housing enclosing a retractable coiled tape, tape tip, and locking mechanism with a suction cup attached to the bottom of the unit. The domed-top of the suction cup is inside the housing and the neck fits a hole in the bottom of the housing allowing the unit to swivel 360 degrees and suction onto a flat surface. This unit will allow students or professionals to draw the illusion of a building having a three-dimensional, realistic contour. What is new in the art to which this invention pertains is that the user can position the unit on a single point and draw all lines pivoting off the same point, like rows of bricks or siding, by simply sliding the tape up or down.
