FILLED REGION IN UNDERLAY

[Ross_Robertson]

Hi,

I am using an underlay set to look up to make a floor plan that shows the ceiling mounted electrical equipment as well as the low level electrical equipment. It displays OK in terms of line work but some of my families have nested detail items with filled regions. These display fine in the actual ceiling plan but not in the underlay. Is there a setting that controls this or do filled regions not show in underlays?

Hmm?  Where to begin?  Could be any number of reasons it is not showing up in the View.  Here's a list of 33:

...or just post the file.  

...if I get only one guess, I'd say the Element's Category is turned off in the View.  How'd I do?

That is how Underlays work, so that they don't obscure elements in main view.
