Revit Vs Civil3D

I have a project coming up that I was told would be in Revit. I’ve used Civil3D for over 10 years. They told me to download it and start looking into it. Is Revit that different? I have no clue what Revit is used for. Can I just do the work in Civil3D and covert it to Revit at the end? I believe I’m only doing a layout plan.
