I tried several times to delete and recreate my markers. At first it appeared to solve the issue, but the behavior was inconsistent. During my last test it worked so my problem is solved even if the origin is still unknown to me.
The letters were created with the built in model text tool within the family editor. I tried to delete them anyway but the error persist.
Good morning, I cannot export the geodetic markers in the joined file. The error message is "Unexpected errors occurred while exporting these elements to the IFC file.". Other posts refers to this issue but the fixes made do not solve the issue on my side. I use the Release 20.3.3.0 For Revit 2020. Thanks for the help.
