Has anybody else had this issue when printing a 3d view to pdf vertical hair-thickness white lines appear down the page?(see attached file) I am using AutoCad for Mac 2012. There is one other computer at this office with AfM 2012 installed and it has the same issue. Increasing the 3D view print quality in Page Setup will only cause more lines to appear. It happens on all page sizes that I've tried (8.5X11 & 11X17).
