Abstract:
An apparatus is provided for use in optimally arranging covering units, such as tiles or the like, or for enabling the precutting of such covering units before such units are applied to the floor or wall or ceiling to be covered. A first prescaled grid is provided on a substantially opaque sheet of paper on which the dimensions of the surface to be covered may be laid out. The exact dimensions of the floor, wall or ceiling to be covered may be laid out to scale on the first substantially opaque sheet. A second grid or line arrangement corresponding to the dimensions of the covering unit is provided on a substantially transparent sheet. This second grid is scaled to correspond to the scaling of the first grid on the substantially opaque sheet. By laying the second grid on the transparent sheet over the first grid, and varying its position, the optimal arrangement of the covering unit may be selected to provide the optimal arrangement of the covering units both for aesthetic purposes and to enable minimum cutting of the covering units. Further, the exact dimensions of each covering unit to be cut may be determined and the covering units may be precut accordingly.
