# Fusion

> Export from Autodesk Fusion straight into Light SDK.

One click sends your Fusion selection (or the whole design) to Light SDK as a `.obj`.

<Note>
  Fusion doesn't have a built-in glTF exporter (unlike Blender/Unity/Unreal), so this
  add-in uses Fusion's native OBJ export instead — Light SDK loads `.obj` directly, but
  materials are simpler than the other plugins' `.glb` (no metallic/roughness).
</Note>

<Steps>
  <Step title="Download the add-in">
    Grab `LightExporter-Fusion.zip` from the [LightSDK releases page](https://github.com/Light-718/LightSDK-releases/releases/latest) and unzip it.
  </Step>

  <Step title="Open Scripts and Add-Ins">
    In Fusion: **Utilities → Add-Ins** (or press `Shift+S`).
  </Step>

  <Step title="Add it">
    **Add-Ins** tab → click the green **+** → select the unzipped **LightExporter** folder.
  </Step>

  <Step title="Run it">
    Select **LightExporter** in the list and click **Run** (tick **Run on Startup** to
    load it automatically next time).
  </Step>
</Steps>

**Use it:** a new **Export to Light** button appears on the **SOLID** tab's **ADD-INS**
panel, at the far right.

Select a single body, face, edge, component, or occurrence, then click **Export to
Light** — a face or edge selection resolves up to its owning body automatically.
Nothing selected (or more than one thing selected) exports the whole active design
instead.

Light SDK opens automatically with your model on macOS. Windows support for this add-in
is untested — check back on [docs.getlight.tech](https://docs.getlight.tech) for updates.
