Abstract: Method and apparatus for producing a detailed plan to a known scale showing an optimized fit of material of predetermined dimensional characteristics into a given area. The invention finds utility in the field of carpet installation. After the perimeter of the area to be carpeted is measured, an array of signals is produced and stored to identify the coordinates of the area. A detailed plan, which is produced by interaction between an operator and the plotting system, shows the area outline, all seam locations, and the length of each strip needed to cover the given area.
