ELEVATIONS LOOK TRANSPARENT

PROBLEM:

Elevation or section views look transparent.

Also Visibility/Graphic settings may have no effect.

CAUSE:

There is a DWG visible in the view that has its insertion point more than 20 miles away.

SOLUTIONS:

Remove the offending DWG.

Hide the offending DWG.

Edit the DWG so its insertion point is not so far away (you may need to re-position the DWG in Revit).
