**Hi**  
**I want to move the polyline collection to be on top of the other collections and it does’t work**

**please see example:**

> **[Cesium Sandcastle](https://sandcastle.cesium.com/index.html?)**
>
> The Cesium Sandcastle provides an interactive environment for testing Cesium code.

**mainly I need a good way to sort different primitives collections**

**I work with v 1.40**

**Thanks**

Hi there,

We’re actually have some upcoming work on z-ordering in the plans. Stay tuned, and see [GitHub issue #4108](https://github.com/AnalyticalGraphicsInc/cesium/issues/4108).

Thanks,
