algorithmic modeling for Rhino



Packrat is once again available!

Thanks to everyone for their interest in the plugin.

You can purchase the plugin here.

Packrat is a bin packing plugin for 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.

There is an option to choose whether sorting of elements and containers should be performed before packing. While sorting usually yields better results, disabling allows the user to perform their own sorting before inputing the elements to PackRat.
There is an input for obstacles within the volume, as well as an option to select whether the objects to be packed may be rotated or not.

PackRat comes in two flavors:
- A limited Evaluation version, available at non cost.
- A full-functioning commercial version.

In addition to those two, version 0.4 of Packrat will remain available for free (non-commercial) use.

The evaluation version has the following limitations:
Maximum number of elements to be packed cannot exceed 30.
Maximum number of containers cannot exceed 3.
The component will notify if any of the two limitations is in effect.

Dear all,

Thank you for the interest in the plugin in the past time. 

I'd like to inform that the plugin is again available (version 0.6), and I'm planning to work on improvements in the near future.

Please take a look here for more information and ordering.
