Autodesk Revit Architecture

I created a logo and have some lines with the filled regions black.  I see the space between the lines black in the motnitor (like 'poche"), but then when I create a PDF of the logo using Nitro PDF Professional V6, the black filled spaces do not show and they neither print.  Only the lines show and print.

I checked the Properties of the .rfa, and the "Filled Region - Solid Fill Black" is checked "visible".

Any ideas why the filled regions are not showing black?

Thanks in advance.

To see if this issue is related to vector processing, I would try using raster processing (in the Print Setup) and see if the issue is affected.

Also, if you have not already done so, it would be a good idea to ensure you have installed the latest update available for Revit.
