T1 is the quickest entry point: one carton type, one loading space, and a 3D result right in your browser.
Choose an edition
Pick the version that matches the cargo rules you cannot change. Step up to a larger edition only when the simpler one falls short.
Single SKU Loading
One carton size loaded into a container, a pallet area, leftover container space, or a larger box.
Mixed Carton Loading
Multiple carton types in one container, with all six box orientations and an interactive quantity panel.
How to choose
Use T1 when
All cartons share the same length, width, and height, and you need either the maximum count that fits or the smallest space for a fixed count.
Use T3 when
Several carton sizes are free to rotate and load directly into the container, with no upright-only rule.
Use U3 when
Cargo is palletized or must stay upright, and you need both automated planning and manual adjustment before shipping.
