I have a free program called PDF factory that lets me "print" to a PDF format to scale and works great. Except I tried to do it with a "shaded" building with sheet metal on as the walls, so evenly spaced vertical lines as the patter. The walls look perfect on the elevation views and the 3D view. but when I try to save the "print" to the PDF view the lines are not evenly spaced and there are not many of them. Is there a better way to export to a PDF? It says when I "print" to my PDF format that Revit will use Raster, could this be causing the problem? If so, how so I use vector?
