2D Load Packer (2DLP) is the unique space optimizer designed to help you plan quickly and easily the best compact arrangement of a number of different size 2D rectangular objects (hereafter called Parts or Boxes) within one or more 2D rectangular enclosures (hereafter Sheets or Containers). 2DLP is based on the truly two-dimensional most dense and quick original packing algorithms. The program may be used to optimize multi-product load plans for any rectangular containers trucks trailers and railcars as well as be applied to free type cutting or any other 2D sheet layout planning or area optimization problem. 2D Load Packer can optimize over multiple containers (sheets) in multiple sizes at the same time taking into account overall item set considered and allowed item orientations specified for each item separately or for all together.An overall load weight limit and truck axle weight limits may be taken into account as additional constraints or actual optimization factors. The program has a facility for specifying the associated cost for each box (part) container (sheet) item in order to calculate totals and affect upon optimization as additional priority factors. Optimizer goal and other main settings are adjustable. Typically optimizer reduces area waste by a factor of 2 - 3 with respect to manual load planning.For real 3D load planning cases which could be reduced to the on floor 2D arrangement of the stacked items using 2DLP instead of 3DLP is preferable.
