Previously, when updating a bolt groupgroup of bolts that forms a connecting building object between an assembly main part and secondary parts

The number of bolts in a bolt group depends on the bolt group shape and the values of bolt distances.

using the old property dialog box, the bolt tolerance changed to 1.0. This has now been fixed.

TTSD-25935 User interface

The Selection filterfilter used for defining which object types can be selected

Selection filter chooses model objects according to object properties.

Selection filters can be standard or user-defined.

For example, selection filters can be used to select parts for drawings or analysis.

list on the Selecting toolbar is now updated in real time when you modify the filters in the Object Groupmodel objects with settings that match the settings that the user has defined for a certain purpose

In Tekla Structures, an object group is used on the one hand to control the transparency and coloring of model objects in the views and on the other in project management. Object groups can also be used in filtering tools, for example in selection filter, to select all objects that match certain properties.

TTSD-25994 Tekla Model Sharing

Tekla Model Sharingcloud service for collaboration and for storing and sharing a model

Tekla Model Sharing is one of the Tekla online services.

:
- If writing out a shared modelmodel used for collaboration over the Tekla Model Sharing service

With a shared model, each user works with their own model and the changes are shared through Tekla Model Sharing. A shared model requires the use of a single-user model. The same model cannot be a shared model and a multi-user model.

fails, the model sharing log and the error log now show more details about the failure.
- Shared models can now be saved even if some of the saved files are locked by other applications, such as antivirus software.

TTSD-26028 Drawings

Document Managertool that is used for listing and managing drawings and other types of documents

With the document manager the user can, for example, reorganize, update, freeze, lock, and delete drawings.

The user can also organize file documents, such as PDF, NC, and DWG files, and drawings, in document categories, and search documents and open drawings.

Document manager is replacing drawing list from the version 2018i onward.

Saving the model with Save as could take a long time because Tekla Structures was recreating drawings. This has now been fixed.

TSAC-2771, TSAC-2769 Concrete components

In Floor layout, the component attribute file list is now properly shown for all components. Previously, it was not properly shown for Meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.
