After running the auto-router in 7.1, you come to the portion of the program marked "Evaluate". My problem is that once I select one to look at, all the other iterations disappear. It takes quite a long time to run several iterations of auto-router simultaneously so it is more than a little frustrating to have all this time wasted by not being able to actually evaluate which run is the most effective, especially when using a ground plane that may fall apart, reducing the initial percentage of completeness drastically.
Is there something I have missed in my reading of the manual that will allow me to save the auto-router work so I may really evaluate which run suits my needs?
