Hi @nirajp . Some couple of year ago when I was working particularly with Archicad only I tried converting Archicad file to IFC and then import into Revit. It was totally a mess at that period. I had shared some issue in the post below
[Validation error with interior door In Revit Pollination plugin]
The issue with IFC conversion I had was data loss during conversion that Revit pollination needed to successfully interpret to create a valid model. I wasted time in cleaning and rectifying missing data for that purpose. But I think as years have passed IFC conversion may have improved. You can give it a try!
