Abstract
A self-contained drafting instrument adapted for rapid measurement of diagrams or drawings on a surface. The instrument utilizes an internal movement detection mechanism, an electronics processing system, and a display screen capable of graphical representation. The movement detection mechanism measures both orthogonal components of movement and the display screen provides a scale that electronically scrolls as the instrument moves or by manually pressing a key on a keyboard. The drafting instrument can be constructed in a number of orientations including a ruler, drafting triangle, protractor, or T-square.
