"In RockSim 7 and 8, I believe there is a 1/2" overlap area for pattern alignment when you have to span more than one sheet. This has been eliminated in RockSim 9, however -- there is NO direct printing feature for patterns anymore. You export the SVG file, then open it up in a program like Corel Draw, where you do your editing before the final print."

Funny, I just printed a 12" long root fin in RockSim 9. Worked the same as in RS8.
