What T3 Helps Answer

SmartPacker is a Windows tool that helps shippers plan container loading, improve space utilization, and cut calculation time. T3 is the standard edition for a known container space and a mixed cargo list: it works out which cargo-quantity combination can be loaded and shows how the resulting plan fits together.

Compared with T1, which handles one carton type, T3 works with several. Unlike U3, T3 can rotate cargo through any of six orientations when the shipment allows it.

Green and red indicators on the cargo-quantity panel show whether each quantity can still be increased—a practical way to tune a mixed FCL shipment without recalculating by hand.

Common Use Cases

Procurement

Fine-tune an order so the cargo fits into a full container load.

Logistics Quotes

Estimate whether a mixed shipment fits and how many containers are needed.

Manufacturing

Plan ongoing shipment quantities against a fill-rate target and loading-feasibility checks.

Basic Workflow

  • Open the included data.xlsx to edit cargo dimensions on the Cargo sheet and the container loading space on the Container sheet.
  • Start with the cargo-quantity panel. Roll the mouse wheel over a quantity box, or type a quantity directly and press Enter to skip the intermediate redraws.
  • Follow the green indicators to add cargo. When indicators turn red, the current cargo type cannot be increased under the current settings.
  • The current version keeps each stack to a single cargo type, so use the indicators and the 3D view together when judging a mixed plan.
  • If your cargo can safely rotate, relax the upright constraint and let T3 explore all six orientations.
  • Use the 3D view, viewing-angle controls, Next Block, and Next Stack to inspect the loading plan step by step.

Changes made in the user interface are saved back to data.xlsx. If you need to preserve the original example data, make a backup copy before editing cargo dimensions.
