can Web viewer app's expand till body level?

Dear community,
is there any web viewer for 3DX available with allos to select part bodies inside a 3dshape?
As far as I could observe all expantion ends at 3dshape level inside web viewer, right?
itself the xCAD Design apps are not supporting bodies.

origin structure at CAD:


expanded at web viewer apps:

 

same with x3D Design:

will it be changed in further time?
Or is there an alternative? Customer presents other viewer application which are able to explore more detailed.
