While building a multi-level model with A Start grids in all levels, we noticed that barriers' 3D visualization can only be switched on or off globally, but not by single barrier. The latter one makes sense to have, if you are working on a lower level to avoid the barriers on a higher level from blocking your view.
For some reason, the right click option "Edit/Show 3D Shape" does not for for barrier objects. They are still drawn, although 3D is switched off....
Please consider for future release. Thx
