# Link sharing and collaboration

Sharing is available in three areas of the LumiDB interface, and works the same way in each:

1. The *Share* button in the top bar
2. After completing a measurement in any measurement tool (Distance, Path, or Area)
3. After cropping an area in the *Area crop* panel

LumiDB supports two main methods for sharing: link sharing and 3D Tiles export. Both require the recipient to have an existing LumiDB account.

### Link sharing

1. Share the current view as a link.
2. Includes all active crops, filters, and selections
3. Preserves all measurements
4. Colleagues can open the exact same view in their browser

### 3D Tiles sharing

1. Export and share the dataset, or a cropped portion, in 3D Tiles format.
2. Can be used in external applications that support Cesium 3D Tiles
3. Enables interactive visualization outside of LumiDB
