Rhino 5 to revit 2018

Hello, I’m having so difficulties to export from rhino to revit, I would like to keep the materiality of the objet or at least have the possibility to add materiality in Revit. I tried by saving in Acis ( sat) but at each time i’m opening in Revit It’s making an grey object that i can’t explose or put materiality on it for a render. I would like to try to save in IFC but i couldn’t find it on Rhino 5.0.

If you can help me…
