REVIT 2026 Won't export to IFC?

[katsanosengineer]

Hello, lately I've been having some issues exporting a project to IFC format. I have both versions 2026 and 2024 downloaded, and have recently switched to 2026. When I exported IFC's from the 2024 version, I had 0 problems doing so, but now, the latest version is giving me issues. It shows this message, (image)

I have no idea what the message might refer to, and since I cannot save the project in an earlier version like you can do in AutoCAD, I'm completely at a loss. 

What can I do?

I have the same problem.. anyone knows the response for that?

Looks like a Windows issue no? Like you try to overwrite the file filename.ifc but that file already exists and you don't have write permissions for that file / directory. I'd try to save to a different directory.

I am also having this issue. Cant get it to work at all.  All permissions etc are fine.

EDIT: I tried saving the IFC to the desktop and that worked. I was originally trying to save to a mapped network drive and that was failing with the above error. I know the permissions are correct in windows as i am able to open and edit all files within the folder i was trying to export the ifc to.

Does your Export IFC window show a version number somewhere. If it does not, your exporter is the out of the box one. Try updating it to the latest version.

Hello @katsanosengineer, if you are saving on a network drive, could you please check if you can save IFC files to the local drive, for example, to C:\Autodesk?
