Optimalcut Web Software is a free, fast, and easy to use web based optimization software that automates the generation of 1D linear cutting patterns and 2D rectangular cutting patterns and 3D rectangular box pack/load patterns. In 1D cutting, 1D pieces are cut linearly out of bars, pipes, tubes, steel bars, metal profiles, extrusions, linear wood boards, etc. In 2D cutting, rectangular pieces are cut out of rectangular sheets made of glass, wood, metal, plastic, paper, etc. In 3D packing/Loading, 3D rectangular objects are packed/loaded into large 3D rectangular containers (boxes). This is especially important in filling containers (containerization) with goods such as in cargo shipping and storage warehouses.
