Hello, how to make PointPrimitive to clamp to ground?

Hi @mwhei

It’s currently not possible to clamp PointPrimitive objects to the ground. A possible workaround could be to use CircleGeometry with GroundPrimitive.

Thank you. When I use ‘CircleGeometry with GroundPrimitive’ and distanceDisplayCondition to add points, It became very slow. Now I use sampling terrain to get the height of the PointPrimitive.
