Mike ….. the viewport I was having issues with is no longer in the layout set. should have made a copy. The sheet I had the problem on was A.02. If I copied a viewport and reassigned my scenes to it or if I created as a new viewport thru the insert I had the same issue regardless of the style assigned to it in the model if I used the viewport as Vector or Hybrid. Raster displayed like it should. Sheet A.03 in the layout set is the same section scenes I was trying to create on A.02 at a smaller scale but I didn;t experience any of the issues I did on A.02. Wierd, but I’d like to try and figure what happened so I can tackle it next time it happens.
