Abstract
A ruler system for measuring workpieces includes a multi-surfaced ruler with rules inscribed along the edges of several surfaces. The ruler contains grooves and T-slots in its surfaces that run along the length of the ruler. In addition, apertures are located in the end surfaces of the ruler. The T-slots and apertures allow several accessories to be attached to the ruler for additional functionality. The accessories include a wheel attachment for drawing parallel lines, storyboard indicators for repeated measurements, a hook rule for measuring from the end of a workpiece, and trammel points for drawing arcs and circles. Connectors may be placed in the grooves of the ruler to link together multiple rulers.
