Can Packer3d be used to optimize the loading of a carton? Can the pallet layout be optimized next, and finally the pallet loading within a vehicle?

All this can be accomplished automatically, in a single pass.
Packer3d Prof and Corp versions as well as Packer3d Main online service will sequentially carry out the following operations:
1. Boxing: http://www.packer3d.com/program/features/tara
2. Palletization: http://www.packer3d.com/program/features/palletising
3. Pallet cargo loading: http://www.packer3d.com/program/features/overview
Optimization is performed in steps 2 and 3.
