AutoCAD Civil 3D

[#1]

I'd like to differentiate between proposed contours and existing contours on my plan views.  Is there a way to show contours at a different thickness and/or color on one surface compared to another surface when both surfaces are displayed at the same time? 

Thanks.

Yes,

Create your new style and apply it to the surface.

Yes copy a surface style snd change display colours
