modifing more than one filled region

[Anonymous]

i am working with revit 2017, and i have imported an autocad file.

the colors changed while importing and so i used filled region with the original colors to cover the wrong new ones.

i would like to be able to scale and modify the filled regions together as a unit, is there a way i can do that?

Import options allow you to preserve the original colors if that's what you want. 

Filled region appearance is driven by type properties - so several instances may have the same type. Beside that, you can use the visibility graphic overrides.

Did you set "Layer Colours" to "Preserve" at the time of Import?
