Hi @jiuxs33, there should be no need to repeat the first last to close the polygon when using PolygonHierarchy.

CesiumJS is a big project, so we use GitHub for feature requests and bug tracking exclusively. In the future, please take any questions to the Cesium Forum where there are members of the community and developers from the team who can help. Thanks!

I delete the last point, but this problem still exists.

Change the polygon's arcType to RHUMB and you'll see the point inside the polygon.
