Unfortuantely, there are some graphical limitations for larger reports. The Graphics display can't get much larger than about 15" square. Other paper sizes can be used, but then you'll need to scale the print (printer settings). That just isn't really pretty as it degrades the image quality (especially if you have labels).
The best I've found is to do this inside Facility Link (if you use a CAD based product, not Revit). You can get a "vector" output which is much crisper for larger sheets. In Facility Manager, all outputs are "raster" which just aren't as crisp.
Hope that helps,
Jon
