I have been using Anyrail with the full license as I eventually hit the limit for the free version and it is very useful. I am only using it for planning thus far and have not built the layout but it has a great users manual and lots of capability like easements on curves.
I agree on Ross switches looking great. And the Gargraves flex track I have a pack of and a pack of Atlas flex. Both look very good. Not sure which I will end up doing the majority of the layout in.
One thing I cannot seem to find is the way to put multiple levels in Anyrail. I see they have layers and elevations but I would love to be able to flip to levels as the plan I have is three levels. One main and one upper and lower. Any suggetions or experience with how to do three levels from anyone?
