Optimize your cargo loads in 3D
Maximize space utilization, reduce freight costs, and eliminate guesswork with our advanced 3D container load planning software.

Built for Logistics Professionals
From auto-optimization to team sharing, 3DLoadCalculator covers the full workflow of planning a shipment.
Optimization
One-Click AI Auto-Plan
Click Auto Plan and the AI engine distributes your entire cargo list across the minimum number of containers needed. It respects weight limits, stacking rules, and orientation constraints — without any manual input.
Multi-Container Optimization
Plan shipments that span multiple containers or trucks in a single project. The algorithm automatically splits cargo across units to maximize utilization, and you can drag items between containers to fine-tune the result.
Built-In Palletization
Mark items as palletizable and the planner auto-packs them onto your configured pallet types first, then loads the pallets into containers. Full round-trip — items to pallets to containers — handled automatically.
Visibility & Safety
Interactive 3D Viewer
Rotate, zoom, and pan through the entire load. Step through the loading sequence one item at a time. Toggle the manifest overlay, center of gravity marker, and container stats — all in the browser, no plugins.
Center of Gravity Analysis
Every container shows its center of gravity position along three axes, rated as Optimal, Acceptable, Warning, or Critical. Catch imbalanced loads before they leave the warehouse — not after a transport incident.
Loading Manifest & PDF Export
Generate a complete PDF loading manifest with top, side, and rear-view diagrams, center of gravity data, per-item constraints, and a document ID. Share it with your warehouse or attach it to the shipment file.
Workflow & Collaboration
Reusable Cargo Library
Store your standard boxes, pallets, and products as reusable templates across all projects. Assign SKUs, colors, and groups. Import hundreds of items from Excel in one upload.
Equipment Library
Save custom container, truck, and pallet configurations for your fleet. Includes a built-in library of standard ISO containers (20ft, 40ft, 40ft HC, 45ft HC) and common trailer types.
Loading Rules
Define rules such as: load groups separately (prevent mixing cargo from different groups), load items in listed order, allow partial stacking (items can be supported by less than their full base), or hexagonal cylinder packing (optimized hex-pattern for cylindrical cargo).
Excel & CSV Import
Drop in your packing list directly from Excel or CSV. The importer validates each row, flags errors with explanations, and shows a preview before committing — so bad data never silently makes it into your plan.
Share Interactive Plans
Generate a public link to your 3D load plan and send it to your warehouse team or customer. They can rotate the view, step through the loading sequence, and verify the plan — without creating an account.
Team Roles & Collaboration
Invite your team with Owner, Admin, or Member roles. All projects, cargo, and equipment libraries are shared across the organization. Scale seats as your team grows.
From packing list to load plan in four steps
No training required. Most teams create their first load plan within 10 minutes.
Add your cargo
Enter item dimensions, weights, quantities, and constraints — or paste directly from your Excel packing list. Mark items as stackable, palletizable, or floor-only. Assign them to groups for advanced routing rules.
