I'm working in a local scene and adding many layers at run time. Some of these layers do not have any z-attributes so they are being added to the 2D layers section in the contents pane. I want to label these layers and am unable to do so unless they are in the 3D layers section. If I manually move them to the 3D layers section, everything works great, however I need to get this working automatically but I am unable to do so. I have found the SceneLayerType property of the layer which appears to be what I would want to set but this property is get only. Layers in the 2D Layers section show up as ArcGIS.Desktop.Mapping.SceneLayerType.SceneLayer2D. Is there anyway to set this property or is there another way to move layers from the 2D Layers section to the 3D Layers section. I know a workaround would be to add z-coordinates to my features so they automatically show up in 3D Layers. The other problem I have though is if I want to add these to a group layer. When I create a group layer, it also automatically gets added as a 2D Layer with no apparent way to change this.
