autodesk forge – Make custom geometry clickable in APS Viewer

There is various way of adding custom geometry in the APS Viewer.

The documentation describes the Overlay method : Add custom geometry
which is great if you want to add additional things in your scene eg. bounding box, lines…
However this is just an overlay; these elements are not added to the scene hierarchy and cannot be selected.

Another approach is to use the Scene Builder which is described in the documentation Custom Geometry with Scene Builder.
