Deleting rulers

Hi Guys, me again
Is there a way of deleting all the rulers on a route in one go? I ask as i am trying to get Pfindley's GCR V6 route to work but the framerate is shocking. I have worked out that the worst points are where the rulers are. Is there a way?
Best, Simon

I don't think you can remove them in one shot. You need to go to the tools pullout and remove them individually by clicking on the arrowheads (I think).

I know what you mean about the performance. I have done the same in quite a few routes in the past. They're not as much of a problem now in T:ANE, but in TS12 and below they'd destroy the performance.
