Assistance needed with RRTRACK and New Lionel Fastrack libraries

I have a layout in Atlas RTS, that I would like converted to Lionel Fastrack. Can anyone assist with this? I know that the new library has the O-84 curves.
Thanks

I can only tell you that Atlas uses 3 pieces of 36" per quarter of their turn verses Lionel uses 2, so you have to split the 36" curve into halves when using the Atlas RTS program.
