ABSTRACT:
A flat file for storing drawings, providing an easy way to pull a drawing from the middle of a stack of drawings without disrupting the previous order of the stack. A movable board mechanism allows one to lift the drawings stacked on top of a selected drawing and hold them while the selected drawing is retrieved. Later the drawing can be replaced under the board mechanism and the stack returned to its original order.
