If you are a Tekla Structures administrator
Required environment changes
You will need to update your copies of the IFC4 standard file, standard.ifc4export.json, and create property set configuration files for IFC4.3 if needed.
-
Re-create the standard.ifc4export.json if you are using the default property set configuration files, for example, Design transfer view default properties.xml or Reference view default properties.xml.
Updated property set configuration files are available in the common environment with the following names:
-
Design transfer view default properties (IFC4).xml
-
Design transfer view default properties (IFC4.3).xml
-
Reference view default properties (IFC4).xml
-
Reference view default properties (IFC4.3).xml
The property set files are located in ..\TeklaStructures\2025.0\Environments\common\inp.
New in AI Cloud Fabrication drawings (Preview)
Collections: Easier re-upload of drawings
Tekla Structures 2025 SP7 introduces a system that alerts if the collection contains drawings that would benefit from being re-uploaded, where a yellow exclamation mark is displayed on the Collections button in the Creation review dialog and on the options button in the Collections dialog. When this icon is displayed, it means that improvements in the drawing creation are available in the latest service pack that can only be applied if the drawings are re-uploaded. Additionally, you can use the new re-upload tool to easily re-upload drawings without needing to open the related models.
The tooltip of the Collections button also indicates that drawing updates are available and re-upload is recommended.
You have now two alternatives for re-uploading:
- If you want to re-upload drawings only from the current model, use the familiar plus button
and upload the drawings from Document manager. - If you want to re-upload drawings that need the re-upload from several models at once, we recommend that you use the new, convenient Update collection dialog.
Re-uploading drawings is a recommendation. Drawing creation will still function normally, but the latest improvements and fixes in the latest service pack might not be implemented.
Re-upload drawings using Document manager
You can now re-upload drawings to the active collection from the current model just as you would add new ones.
-
Simply select the drawings from Document manager and click the plus button
in the Collections dialog, like before. -
If there are only new drawings in the selection, the drawings will be uploaded as usual.
-
Outdated drawings (missing parts, quality decreased, etc) will be ignored in the upload.
-
If the active collection already contains other versions of some of the drawings you are adding, a dialog will be displayed asking how you want to add the drawings.
The drawing you are adding might have been created in an older Tekla Structures version and you are uploading the drawing using a newer Tekla Structures version, or the local drawing has been modified and saved and is now different than the drawing version in the cloud.
-
- Select what you want to do:
-
Remove and replace: Deletes all existing versions of the drawings and replaces them with the new added drawings. Adding drawings with a newer Tekla Structures version will not be compatible for users of older Tekla Structures versions.
-
Add new versions: Adds the new versions of the drawings. This will not remove the existing versions of the drawings.
-
Re-upload drawings using Update collection dialog
You can efficiently manage and update multiple drawings through an intuitive interface that organizes content by model and offers real-time progress tracking.
Note: If you are using the Update collection dialog to re-upload drawings in the currently open model, we recommend that you save the model beforehand, so that the latest drawing status can be retrieved.
-
To re-upload existing drawings with the latest data, click the
options button in the Collections dialog and select the new option, Re-upload drawings.
The new Update collection dialog lists the drawings organized by model, with sortable column data.
- Define the model locations. To list only outdated drawings, select the Show only drawings that need re-upload checkbox at the top. The Tekla Structures version used for creating the drawings is shown in the Version column.
- Select which drawings you want to upload:
-
To upload only the selected drawings, select the checkboxes next to the desired drawings.
-
To upload all outdated drawings in a model, select the checkbox next to the model.
-
To upload all outdated drawings, select the Re-upload checkbox on the title row.
-
-
Click Update and select one of the following options:
- Update existing collection: The outdated drawings in the collection will be updated with new versions. This option uploads the latest drawing version and removes all other versions of that drawing. This is the best option if you want to maintain your current collection structure.
- Duplicate existing collection: The active collection will be duplicated and the drawings will be uploaded there. Select this if you want to keep the original versions separate.
- If the model that contains the drawings to re-upload is the same model you have open, you will be asked to save the model to apply the latest changes and continue with the upload. Click Save.
- If the model was created in an older Tekla Structures version, and you save the model, you can no longer open the model in an older Tekla Structures version. You will be asked if you want to continue with saving. Click Yes to continue.
The uploading starts and the message 
Processing is displayed next to the drawings being uploaded. You can follow the upload process at the bottom of the dialog.
You can cancel all ongoing tasks by clicking Cancel. This will not undo the changes that have already been done in the current collection. The Process cancelled message is displayed for all rows that are being processed.
When the drawings have been uploaded, the message changes to 
Updated and the Cancel button changes to Close.
An error message is displayed, for example, when:
- A drawing is missing or not available.
- A model path is incorrect or missing.
- The drawing is out of date or there was an extraction error.
- Some technical errors occurred.

Other improvements in AI Cloud Fabrication drawings
-
Earlier, you could not re-upload drawings manually from Document manager using the
plus button when the drawing was modified or when you were uploading from a newer Tekla Structures version. This issue has now been fixed, and re-uploading succeeds.TTSD-74129
- Now, when all drawings selected for upload are outdated or need renumbering, a new, more informative message is displayed asking to update the drawings by using Update in Document manager or by opening and saving the drawing. The previous message was misleading and did not contain enough details.
TTSD-73296
- Previously, the drawing upload could start with a significant delay. This issue has now been fixed.

Tekla PowerFab Connector fixes
- In the Submittal history for Tekla
PowerFab export, Issued by now shows the correct issuer name. Previously, the current user's name was shown, even if the current user was not the issuer.
TTSD-74431
- Previously, when exporting a fabrication package using Drawings for external approvalwith a drawing type selected, extra assemblies and parts were being exported. This issue has now been fixed.
