Most developers underestimate how annoying 3D packing logic actually is until they try building it. At first it sounds simple: “Just fit products into boxes.” Then suddenly you’re dealing with: rotations weight limits stacking rules utilization % multiple box sizes container loading item coordinates upright-only products I was recently testing different approaches for cartonization and load optimization and realized why most companies avoid building this in-house. Even basic scenarios get complicated fast. For example: Which box creates the least wasted space? How do you split 200 products across pallets? What’s the most efficient truck/container arrangement? Which items should rotate and which shouldn’t? I ended up playing with a few APIs and visualization tools to understand how others solve this problem.…
