How is 3D loading simulation different from a CBM calculation?
A CBM calculator tells you how much total volume you have. This tool shows you how that cargo actually gets arranged inside a container or on a pallet. When you mix cargo of different sizes, the theoretical CBM total can be smaller than the container's volume, yet the shipment still doesn't fit in practice — because of rotation constraints and required clearance (gap) between items, a problem that comes up constantly in real operations.
This simulator takes your cargo list and container/pallet dimensions and computes the actual layout using a z→x→y shelf-packing algorithm, visualizing center of gravity and collisions in 3D. If cargo doesn't fit in one container, it automatically splits the load across multiple containers, and you can download the results as a PDF report.
Frequently Asked Questions
Q. Can the actual loading count differ from the theoretical CBM math?
A. Yes. This tool uses a shelf-packing heuristic rather than a fully optimal bin-packing solver, so depending on cargo shape, rotation settings, and clearance, the result may come in below the theoretical maximum — but it shows a layout that's actually achievable in practice.
Q. What happens if cargo doesn't fit in one container?
A. The multi-container auto-allocation feature continues placing the remaining cargo into new containers. If an item exceeds container dimensions entirely, or the max container count is reached, those items are flagged separately.
Q. Can I use the results for an internal report?
A. Yes. You can download a PDF report with a 3D snapshot of the loading layout and summary statistics — ready to use for internal reporting or discussions with a packaging vendor.
