polpero, I was able to create a .pdf file with the lines as well as modifying the thickness of the lines as you will see in the pdf file attached. My only concern is the "line style" backLine.02 as you see in my screenshot... I had to remove the style before I was able to print them, because that style is set to 'hairline' thickness and that has never worked for me in the past. Not sure if this will help...
