Dimension associativitydrawing property that represents the linking of drawing objects to model objects so that the former are updated according to changes made to the latter in the modeling mode

In Tekla Structures, associativity only relates to one type of drawing objects, namely associative objects. These can be building objects and associative annotation objects.

In Tekla Structures, the term associativity has traditionally been used when referring to the linking of drawing objects to model objects. In other modeling contexts, however, the term associativity may refer to any kind of linking between model objects or parts of a model by using dependencies.

rules are now sorted and show more clearly if the rule is associated to a reference pointpoint that Tekla Structures creates when the user creates a model object, the point being visualized as a handle

The reference points follow the model object if it is moved. They are only deleted if the related model object is deleted.

Reference points can be selected as snap points in a snap switch.

service when reading in or joining a model. This was most likely related to limited internet bandwidth when several packets were read in or when joining a large model. The issue has now been fixed in this service pack.

If you are a Tekla Model Sharing on-premises server user, note that this Tekla Structures service pack is not compatible with on-premises server versions older than version 3.13.9. To continue using Tekla Model Sharing, you need to update the Tekla Model Sharing on-premises server to version 3.13.9.

Tekla Model Sharing on-premises server version 3.13.9 is downward compatible. All previous Tekla Structures versions in which Tekla Model Sharing is available, starting from Tekla Structures 21.0, work with this server version.

TTSD-38820 Tekla Model Sharing

Previously, when inviting users to 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.

in the Start sharing dialog box, the email addresses that had capital letters were temporarily shown as duplicated in the list of users until you reopened the dialog box. There were also issues in receiving email invitations to the model. Now this has been fixed.

TTSD-38578 Tekla Model Sharing

A new Add button has been added to the Convert to multi-user modelmodel that is used for collaboration and that is opened in multi-user mode

dialog box, so that you can easily add a new multi-user server name to the server list when you are converting a single-user modelmodel that is opened in single-user mode

to a multi-user model.

TTSD-37993 Tekla Model Sharing

Previously, excluding a folder from sharing only worked for folders directly under the model folderfolder that is used for storing files associated with a model

Tekla Structures stores all files associated with a model in a folder it creates with the same name as the model database (.db1).

In multi-user mode all users access the same model folder.

, not for sub-folders. This has now been fixed.

TTSD-37935 Tekla Model Sharing

Previously, start sharing and write out could sometimes fail if the temporary packet creation file was locked by another applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

Previously, the construction arcconstruction object that represents an arc defined by three points

and construction circleconstruction object that represents a circle

creation commands did not follow the snapping depth (Plane/3D/Auto) and snapping plane type (View/Work). This raised several issues, in particular:

  • When creating construction circles by center point and radius in the plan view, the circles were created at different elevations depending on the start point.
  • When creating construction circles by three points on the plan views, the command snapped to points on objects, causing the resulting circles to be out of the plan views.

These issues have now been fixed. The construction arc and circle commands now follow the snapping depth and snapping plane type.
