PackRat is a 3D bin packing component for McNeel Grasshopper.
Packrat accepts a list of containers and a list of items to be packed. Only rectangular items are recognized, so if the input consists of arbitrarily shaped BReps, their bounding boxes will be considered. It outputs a GH_Structure of items per container, and a supplementary list of items that did not fit in any container.
The plugin will be immediately available for download after purchasing (version 0.6).
