I'm not familiar with Revit (I use Archicad and several other programs). Try this link
I generally have to play around with several saves/export settings and then Cura scalings before getting it right. Eventually I will make an instruction sheet for my own set up so I suggest you write down what you do. In any case you will likely need the "real scale", which is simply the actual scale (1:20, 1:50, 1:500, etc . . .) that you see in metric but for the imperial measuring system. So 1/16" = 1'-0" equals a real scale of 1:192 because there are 16 1/16" in an inch and 12 inches in a foot (16x12=192). When you convert this to a percentage 1/192 to get .52083%. Depending how you imported into Cura that percentage scale will likely be the correct one. I hope this helps, - it is not an intuitive process, so keep trying and you'll get it.
