Tekla Structural Designer 2023 and Tekla Tedds 2023

This update is required and is automatically installed when installing either Tekla Structural Designer 2023 or Tekla Tedds 2023.

Sentinel RMS Server Licensing

This update should be applied to existing Sentinel RMS license servers before you install Tekla Structural Designer 2023, Tekla Tedds 2023, Tekla Portal Frame Designer 23 or Tekla Connection Designer 23. We also recommend activating your new Product Activation Keys on the license server before installing these new product versions on your client devices.


Please note that when this update is installed on a license server the license server will be using Sentinel RMS 10.0 but the products will continue to use Sentinel RMS 9.7.

Portal Frame Designer

When this update is installed and a Tekla Online license is used with Portal Frame Designer it is possible to design using plated girder sections. This improvement applies to Portal Frame Designer versions 23, 22, 21, 20, 19 and 18, however the plated girder feature may cause issues with version of Tekla Portal Frame Designer earlier than version 23, therefore it is strongly recommended that when installing this update or Tekla Structural Designer 2023 or Tekla Tedds 2023 that you also upgrade Tekla Portal Frame Designer to version 23.
