Patent ID: 7594341

Claim:
A method of determining a scaled distance on a blueprint and transferring the determined distance to a building material, the method comprising: providing a tape measure having a first set of indicia spaced at one inch intervals on a first side of a tape, and a second set of indicia on a second side of the tape spaced at intervals correlating to a scaled ratio compared to the first set of indicia, said scaled ratio conforming to a scaled ratio of the blueprint, wherein both the first and second set of indicia ascend numerically in a direction away from a starting point at an end of the tape; placing the second side of the tape adjacent the portion of the blueprint to be measured, such that the starting point of the tape aligns with at least one end of the distance to be measured; determining on the second side of the tape a distance from the staring point to an end point of the distance to be measured; reading a value from the second side of the tape at the distance to be measured; placing the first side of the tape on the building material; extending the tape until the distance extended on the first side corresponds to the value read from the second side; and marking the distance on the building material.
