problem view in plant

[DeDios]

Good morning.
I take advantage of your kindness to ask you another doubt:
In my plants I would like to see the ground floor on every floor. the problem solved it with the "view range" command (i.e. the view range), setting the ground floor as a reference depth. here, I would like all that is under the reference plant to be in tones (gray), and here is my question: by manually selecting the elements it is possible to modify the graphics in the plant setting them in "half tones" but I was wondering.. there is a command that automatically sets all the elements below the reference plant in "half tones" ? thanks in advance :d

for the views below, in the properties of the view of the plant (level), there is the special field "understanding" where you can assign the necessary level.
in the 2014 version the view below puts it in grey

there is also in 2013, and also here it is put in tones but...si "superappone" with the reference plant (as if there were transparent soles). Instead, taking advantage of the depth of the view only the elements actually visible are displayed, only that.. are not in "half tones" and touches you, unless you have a special command, manually select all the elements and "overwrite" their display in "half tones".
