Builder
Workflow: set plies → pick a material per ply from the library → visualize exploded isometric stack + total thickness.
Material library (JSON)
Each material needs: name, thickness_in, color (hex). Optional: notes.
Layers: 0
Total: 0.00 in
Drag: rotate • Wheel: zoom • Right-drag: pan
Tip: Make "core" thick (e.g., foam 0.2in) and watch the total jump.
Ctrl/Cmd + wheel also zooms on some browsers.
