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?
In the Print dialog, click the "Setup..." button towards the bottom. In the following "Print Setup" dialog, you'll see and option to choose "Vector Processing" towards the center of that dialog.
