3D: Is clamp on ground / ground clamping working?

I set up a ArcGIS Portal, ArcGIS for Server, federate them and setup a couple of Map Image Layer, Scene Layer Packages, Elevation Layer etc.

In our application this services are consumed using ArcGisRuntime for Qt (no QML).


Since a a few weeks i try to add  a single building (as 3D model [flt] or geodatabase [gdb] containing a block of building).

They are visible using simple conditions:

  • using no elevationLayer/baseSurface
  • using an absolute height of the 3D objects

So, some basic functions are working.


My expected workflow is:

  • add basemap
  • add elevation source
  • add some 3D objects (single building / block of building) USING "On Ground" / clamp on ground / ground clamping


But i run into different behaviour if i

  • use the elevationLayer -> often the model isn´t visible anymore (even if i set the basemap invisible)
  • assign the elevation parameter "On Ground" to the object(s) (single building / block of building) -> still flying at absolute height


Is my workflow correct? Any hints?

Are there any known issues (Release notes for 100.1—ArcGIS Runtime SDK for Qt | ArcGIS for Developers) relevant?

Especially "Z-aware feature layers do not render correctly in scene view." let me think, if it´s relevant to me. But i am not sure...


Any help is welcome!

Thanks in advance
