How to Fix "Unexpected errors occurred while exporting these elements to the IFC file" when exporting IFC from Revit

Even using the latest IFC exporter addin, it may still have problems with some elements, causing the message:
Unexpected errors occurred while exporting these elements to the IFC file

I used these steps to work around this issue:

  1. Open Revit model
  2. Neutralize coordinates (for explanation and steps see here)
  3. Tried the export, which failed, with this error
  4. Then got the element ID from the error report
  5. Went to a suitable 3D view for export
  6. Hid that element in the View
  7. Modified the IFC export settings to use “elements in view”
  8. Re-exported, which now worked without error. 
Hope it helps!
