I’d like to ability to suppress any Plug-In Object to display as 2D-only or 3D-only. For example, I often end creating symbols that contain both custom 3D geometry along with a PIO (such as a Television object, Truss, Lighting Device, or Window). I often want this to a be a 3D-only symbol, but the included PIO forces it to become a hybrid symbol which then only displays the 2D PIO and none of the my 3D geometry (when in Top/Plan).   A current workaround is to “Convert to Group” leaving
