First Claim
1. A ruler assembly, said assembly comprising:
- a ruler having a top extending along a ruler width and a ruler length;
the top having an inner top surface and an outer top surface;
at least one side wall extending along the ruler length;
the at least one side wall having an inner side wall surface and an outer side wall surface;
the outer side wall surface extending along the ruler length and generally perpendicular to the outer top surface;
the inner top surface and the inner side wall surface defining a ruler cavity;
the at least one side wall extending from a side wall bottom edge to a side wall top edge proximal to the outer top surface; and
the outer top surface comprising a plurality of step surfaces each having a step height measured from the side wall bottom edge to the side wall top edge of each of the plurality of step surfaces.

Abstract
A ruler assembly comprising a ruler having a top extending along a ruler width and a ruler length. The top has an inner top surface and an outer top surface. The assembly has at least one side wall extending along the ruler length. The side wall extends from a side wall bottom edge to a side wall top edge proximal to the outer top surface. The outer top surface comprises a plurality of step surfaces, each having a step height measured from the side wall bottom edge to the side wall top edge of each of the plurality of step surfaces. In some embodiments, the inner top surface and the inner side wall surface define a ruler cavity configured to removably couple to an insert ruler.

20. A method of determining a measurement between a first surface and a second surface using a ruler assembly, the method comprising:
-
providing a ruler assembly comprising; a top having an inner top surface and an outer top surface, at least one side wall extending along a ruler length, the at least one side wall having an inner side wall surface and an outer side wall surface, the at least one side wall extending from a side wall bottom edge to a side wall top edge proximal to the outer top surface, the outer top surface comprising a plurality of step surfaces each having a step height measured from the side wall bottom edge to the side wall top edge of each of the plurality of step surfaces; positioning the ruler assembly between the first surface and the second surface whereby the outer top surface is proximal to the first surface and the side wall bottom edge is proximal to the second surface; aligning the side wall bottom edge with the second surface; aligning one of the plurality of step surfaces with the first surface; and determining the measurement between the first surface and the second surface as the step height corresponding to the step surface aligning with the first surface.
