Hi

I recently upgraded FME Form from 2025.0 to 2026.1.1 and my workspace for processing IFC files no longer seems to work. So far, I have noticed these issues:

  • FME 2026 does not detect the same attributes, such as BIP.IfcGUID.NominalValue
  • I removed the reader and added it again and FME now seems to replace BIP.IfcGUID.NominalValue with BIP.IfcGUID.
  • The “Door” subset now seems to cointain thousands of attributes, which was not the case in FME 2025. This makes FME very slow to work with.
  • Saving the workspace now takes several minutes and the .fmw file has grown from around 0,9 MB to 21 MB.
  • Opening the workspace takes several minutes as well.

 

Has anyone else noticed these issues?

    I shoud add that removing the “Door” item solves the issues with the massive file size and makes FME responsive again.
