Have Revit 2015 installed and used to project that was created with Revit 2014. Everything else is working, but we can't get IFC exported. Revits own exporter turns back 4002 errors (walls, families etc.) and no *IFC file creted. We tried IFC exporter 2015, but it doesn't give any IFC-file either or any errors. It just stops exporting after while. I tried to save some of the families that had error as Revit 2015 and reloaded them to the project, but still unexpected errors count 4002 and same families are on the list.
With this project we need almost every week to make IFC-file which will be checked with engineers models - project has now progressed over a week with Revit 2015 so we really wouldn't want to go back to Revit 2014. With Revit2014 we didn't have major issues creating IFC.
Has anyone any clue what to try?
