2020 SP4: New features and improvements

Document manager improvements

Show selected documents only mode improved

  • When you activated the Show selected documents only mode, Document manager did not show documents that were then created or modified. This has now been fixed so that new and changed documents are shown, as long as they match the active search and selected category criteria. These documents will then appear in the list as unselected to distinguish them from the already selected documents.


Improvement in issuing drawings

  • If you selected a set of drawings to be issued in the Document manager list, and one of the selected drawings has already been issued, then the Issue command was not available in the context menu. The same problem existed with unissuing if one of the selected drawings was not currently issued. This has now been fixed so that Issue and Unissue context menu commands are always visible regardless of the issuing state of the selected drawings.


Order of drawings in Print Drawings dialog box

  • The order of drawings in the Print Drawings dialog box now matches the order they appeared in Document manager at the point in time when the Print Drawings dialog box was opened.


Zoom to selected works for templates in drawings

  • Previously, the Zoom to selected command in drawings did not work for templates. This has now been implemented. You can select more than one template.

Curved line accuracy increased in reference models

  • The accuracy of curved lines in reference models has been increased, and now there are four times more segments in curves. Earlier, curved lines sometimes turned into sets of straight lines after reference modelmodel which the designer can use as an aid when building another model

    A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

    For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.


    The LargeTessellationPerCircle setting in the TrimBimPlugin.config configuration file used to be hard coded to 48, now 192 is the default value. If you have problems with the performance, you can decrease the value in TrimBimPlugin.config, which is located in the .\bin\referenceplugin\trimbim folder.

    This setting affects all new inserted and updated reference models. For existing reference models, you need to delete the reference model and reinsert it to use the new value.

    This improvement applies to all reference model formats.


.tekla models contain pours, pour units, and grids

Pours and pour units

Pours and pour units are now included when you upload your Tekla Structures model to the linked Trimble Connect(1) application for information sharing and collaboration for construction projects that is based on the Trimble Connect platform

(1) Reference models are used in Trimble Connect application instead of using import and export.

(1) Trimble Connect application includes web, desktop and mobile clients, and the Sync tool, for example.

(2) Trimble’s platform for microservices in the cloud

(2) Trimble Connect platform’s microservices include services for uploading, storing, processing, and managing or consuming data. These services are meant to provide common solutions required by multiple applications.

project as a .tekla model. The properties of pours and pour units are also included in the upload.

Note that to use pours and pour units instead of cast units and cast unit parts in your .tekla models, pour management needs to be enabled. For more information, see Enable pour management.

Grids are now also included when you upload your Tekla Structures model to the linked Trimble Connect project as a .tekla model.


  • grids are not shown in overlay models

  • radial grids can look slightly different in reference models and in Trimble Connect for Browser compared to native Tekla Structures models

Improvements in components

Concrete components

  • Precast found block (1028)

    On the Parts tab, you can now use the new Create filling option to create a filling between the column and the first created block.


Steel components

  • U.S. Base plate connection (71)

    On the Parts tab, you can now separately define the properties for stiffeners 3, 6 and stiffeners 7, 8.
