Hi there, I have been trying to export a plumbing model into IFC file from Revit 2024 and 2022. The elbows are displayed well in the Revit. But there are no elbows in the IFC file. I have tried different exporting settings, such as "IFC4 Reference View", "IFC4 Design Transfer View", the high geometry level of detail, 'Allow use of mixed "Solid Model" representation', 'Keep Tasselled Geometry as Triangulation', etc. Does anyone have any ideas on how to resolve this issue? Appreciate any help. Tha...

For example, I got two ifc files, one named A and the other named B. Now I'd like to copy a certain element(like a beam) from A to B, so that the beam can be shown in the model B when file B is opened with ifc viewer. What I have tried is to extract the related geometry entities of IFCBEAM(like IFCTRIANGULATEDFACESSET, IFCPRODUCTDEFINITIONSHAPE) from A, then paste them to B. But it failed. Is there any other ideas, methods or functions in IfcOpenShell which can make it? Thanks.
