Hi，My Name is Zhao.

And Now I am confused in how to build myself custom primitive with my vertex data?

some shape that the Entity is not support.

or how can I search some useful Information to build it.

Thanks a lot.

Hi Zhao,

While a little less simple than working with the Entity API, you can try using [the lower-level geometries](https://cesiumjs.org/tutorials/Geometry-and-Appearances/).

Hope that helps.

Thanks!

Gabby

Hi Gabby，

Thank you very much for your reply.This is my Problem：

I can’t use primitive like BoxGeometry too, because I want to build a geometry like tetrahedron ,4 vertex or 5 vertex…

and I can’t find any information in sandbox or your tutorials.Can you give me some guidance?

By the way, I found some images of sensor in your cesiumPro.

How can I get cesiumPro and How to buy it?

Thanks a lot.

Hi Zhao,

I think the closest you could get is create a [PolylineGeometry](https://cesiumjs.org/Cesium/Build/Documentation/PolygonGeometry.html) and extrude the height for a volume. If that’s not sufficient, could you perhaps create a [model](https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=3D%20Models.html&label=Showcases) from your data?

Email [todd@agi.com](mailto:todd@agi.com) for info on CesiumPro.

Thanks!

Gabby
