About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
The RFA & RVT Geometry Exchange Add-on for ARCHICAD 21 is available for FREE now.
The RFA & RVT Geometry Exchange for ARCHICAD 21 enables ARCHICAD users to import RFA (Revit Families) into their ARCHICAD project as objects including doors and windows. It will also enable ARCHICAD users to hotlink, import and export RVT geometry (Revit projects) in and out of ARCHICAD. This is not a replacement for IFC workflows but intended for comparing imported RVT geometry to an ARCHICAD model and exporting RVT geometry for comparison to a Revit model.
