On [Measure - Cesium Documentation](https://cesium.com/docs/analytics-sdk-reference/Measure.html)

##### Demo:

- [Cesium Sandcastle Measure Widget Demo](https://cesium.com/Apps/Sandcastle/index.html?src=Measure%20Widget.html)

Link is broken to [https://cesium.com/Apps/Sandcastle/index.html?src=Measure%20Widget.html](https://cesium.com/Apps/Sandcastle/index.html?src=Measure%20Widget.html)

Incidentally, where can I play with the Cesium Ion measurement tools?

Thank you for your post - I just reported the broken link internally. Cesium ion SDK provides users with an analytic toolkit, them to unlock insights from their geospatial and 3D data. Here is a high-level guide to Cesium ion SDK:

> **[Cesium ion SDK](https://cesium.com/platform/cesiumjs/ion-sdk/)**
>
> The Cesium ion SDK extends the open source CesiumJS visualization engine with tools like sensor geometries and visibility analytics. Measure distance and areas, perform line of sight, viewshed, and visibility analysis, and include ready-to-use UI...

Cesium ion SDK will give you access to the measurement tools that you are looking for. It also includes tools for calculating volume, etc. Let me know if you have any other questions or concerns.
