Tekla Structures 2022 SP3 stops with non-IFC reference models

Tekla Structures 2022 SP3 version contained an error that caused critical issues for models having DWG or other non-IFC reference models visible in the model view. IFC reference models were not affected.  For example, when representation was changed into standard Tekla Structures suddenly closed and the following error message was shown:

"A critical error has occurred.

The application is going to close.

Error message: External component has thrown an exception."

The error was happening when Tekla Structures fetched reference model attributes from reference objects. This error has been fixed in Tekla Structures 2022 SP4 version.  We have taken the SP3 version away from the Downloads service. We recommend installing the 2022 SP4 version.
