Contributor guide
Research direction
Start by reproducing the export with Revit 2024.3.x and IFC for Revit Addon 24.3.2, then compare the CurtainWall PredefinedType and ObjectType values with those shown in Revit. The fix is complete when a CurtainWall configured as USERDEFINED exports that type and its ObjectType instead of NOTDEFINED; verify the result against Revit 2025 as well.
