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.
I download & Install "ARCHICAD Connection for Revit 2016"
When use "Improved IFC Import" funtion,and select ifc file to open
It's show Error message "The selected IFC file cannot be read, because its version is not supported. Obtain the file in IFC 2x3 format (or convert it), then try again."
