Web 3D Dock Designer

I want to give my customers the same smooth, browser-based experience shown at https://dockdesigner.ez-dock.com/guest/editor/top, but under my own brand. The goal is a full-featured, interactive 3D dock-design tool that runs entirely on the web. When a user opens the page they should be able to drag, snap, rotate and connect floating dock sections in real time, orbit the camera, and instantly see overall dimensions.

Note: Start from Scratch Only --
Begin from the shore and build a dock layout using standard dock sizes
Frame Sizes

4ft x 8ft, 4ft x 10ft, 4ft x 12ft, 4ft x 14ft

6ft x 8ft, 6ft x 10ft, 6ft x 12ft, 6ft x 14ft

All the above frames can be portrait or landscape. ( they can rotate to make up configuration.



Core requirements
• Purely web-based—no installs or plugins.
• True interactive 3D (think Three.js, Babylon.js, WebGL; your choice).
• Modular asset library so I can add or edit dock pieces later.
• Live measurement read-outs plus an auto-generated parts list and optional pricing.
• Export options: image or PDF snapshot and CSV/JSON bill of materials.
• Simple admin area to view, edit or download saved designs.

Performance benchmarks: maintain 60 fps on a mid-range laptop with at least 50 modules in the scene, and work cleanly on Chrome, Edge and Safari without console errors.

When you’re done I’ll need the full, well-commented source code, build/deploy instructions and a brief screen-recorded demo that proves all listed features work.
