I'm trying to link or open the attached IFC-file in Revit 2022.1.21.13 (Ifc Exporter 22.4) but it doesn't show anything. When I try to open it I get an error that it is unable to open it. When I try it in Revit 2021 it works fine.
Unable to import/open an IFC file in Revit 2022. The file appears to keep loading for more than thirty minutes but does not succeed or nothing is imported.
Causes:
IFC is too large and complex.
IFC is imported and exported from Revit. Revit IFC workflow was originally not designed for the situation "roundtrip" between different Revit versions, but primarily for the communication with other software.
IFC4 file.
IFC4x1 file.
Solution:
To resolve this issue, try one or more of the following:
Link the IFC into Revit rather than opening it.
Divide IFC model into smaller parts and link smaller IFCs instead, because *.IFC.RVT created by Linking must be smaller than 2GB.
If IFC is imported and exported from Revit, refer the information given below:
The IFC format is designed to export specific data and share the data with other software products. Exporting and importing data from and to the same software, or round-tripping, is neither supported or certified from the creator of the format IFC Building Smart.
In the case of IFC4 file, use Revit 2022 or newer.
In case of IFC file size 1+GB, use Revit 2022.1 or newer.
