adjust color drawing view

what about drawing rules? You can set (if it's a ) Reference to a grey Color.

I hive this a try,

but NO, the DV does not rendered grey

1007.test.dgn

this is a simple file, (elements between the walls are simple shapes)

attached the same file :  this renders grey

attached the drawing view : this is not affected

I have set the view to "grey" (new display style)
in this display style there is a display rule to render references to presentation grey

so the simple reference is rendered correct,
the drawing view is not affected even this is reference

if I change presentation in the drawing view itself, the view can be rendered in grey

so it is necessary to make a separated file to be used as the underlay where all styles are set.
in a dgnlib, the display styles for grey must be set ( front / back / cut ) & reference grey (display rule)
the DV presentation setting: synchronize View must be set to Volume only, so the "clip Volume" settings for forward / back can be changed,

a lot of styles and rules and sub files must be created to do a simple grey out for an underlay

anyone having a more simple way to do this?

The Drawing Model use forward and cut drawing as Display Style. So assign the Rule to these Styles.

and I use Symbolgy Overrides.

Can you use that per reference? So that ventilation is brown and electric is red etc.

And per level?

yes you can filter the View for most Element Attributes. And you can ask for different Attributes with an AND/OR Statement

Interesting.

But isn't it more more work than just select levels and set symbology?

With Display Rules you can change the Attributes for different Elements on the same Level. For Example Concrete Walls, all on Level A_WALL_Concrete with different Fire Rating's. And you can have multiple Display Rules but just one Levelsymbology Override Setting.
