Color scheme hidden by imported DWG file

[IMCornish]

I have an imported dwg file, being a map, on which I am trying to indicate a building plot using an External Area.  The view (an Area Plan)  has a  Color Scheme applied, being different colored hatch patterns for each area type.  I am wanting to preserve the colored hatch layers of the dwg but the 'Color Scheme' hatch applied to the view, even though I have located the Color Scheme in the Foreground, is not apparent.  I have even dropped the dwg to a level below that of the Areas but this has no effect.

See the partial screen capture attached.  The Red Boundary should have red diagonal hatch and the Blue Boundary should have blue diagonal hatch.

Any ides please.

Have you tried making the DWG Link transparent? This must be done by element - select the Link, right-click, select 'Override Graphics in View' ► 'By Element', and then set the Surface Transparency to 100%.

The problem with your suggestion is that all the color is taken out of the map. However, I set the transparency to 50% and it showed the hatch.  This led me to experiment by lowering the transparency setting and eventually I got it down to 1% and the hatch shows fine!  Thanks for the your interest in helping and putting me on the right track.
