Longitudinal reinforcement (70) now recognizes cuts in the concrete parts.

In 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.

(20), previously, welding was not created when you only specified the below line weld properties for weld 2. This has now been fixed.

In Haunchcomponent object that represents a wedge-like structure that strengthens a beam at its end

(40), an unwanted chamfer was previously created on the partial stiffenercomponent object that represents a structure that strengthens a steel beam or column

Stiffeners are usually plates.

, when you clicked  and moved the mouse over the Color set command, the command stayed highlighted even when you moved the mouse away from the command. This has now been fixed.

IFC2x3 export: Curved rebars are now exported with more accurate geometry when you use the Surface geometry export type.

Reference models: Tekla Structures crashed when you pressed the Pick button in the Add model dialog box while hiding the existing reference files. This has now been fixed.

IFC4 export: Curved beambeam that follows the form of an arc

Steel curved beams can be created by picking three points, where a point between the start point and the end point defines the arc. Both steel and concrete curved beams can be created by adjusting radius in beam properties or by using polybeams.

IFCfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

object conversion: Cut row in changes cannot be opened at some cases. This has now been fixed.

IFC2x3 export: The gridmodeling aid that represents a three-dimensional complex of horizontal and vertical planes

In Tekla Structures, grids are used as an aid in locating objects in a model. The grid is shown on the view plane by dash-and-dot lines. It is also possible to show grids and grid line labels in drawings, and to modify grid properties in the drawings.

It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

is now exported to the same location as the model when you use the Location by: Work planeplane that the user has chosen in a model and that is currently active for working on in a model view

Newly created, copied, or moved model objects comply with the work plane. For example, shifting the work plane to follow a sloped plane makes it easier to model sloped structures.

option.

Tekla Structures does not crash anymore when modifying a drawing even if the UDAobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

definitions are missing from the objects.inp.
The User-defined attributes dialog box is not available at all in the drawing dialog box  if UDAs are missing from the environment. Previously,clicking the panel caused an 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

DWG drawing export: Drawing DWG export is now bit more robust with handling custom drawing of parts.

Drawings with custom plug-ins using lots of graphical objects, such as lines, or rectangles, have now slightly better performance.

Marks sometimes lost the Position element when you used mark alignment tools in drawings. This has now been fixed.

When prompted for mark content when creating an empty mark, the associativity symbolgraphic that Tekla Structures creates in a drawing and that indicates that an associativity point of a drawing object is associative

The associativity symbol changes if the associativity point is not associative.

was not correctly drawn. This has now been fixed.

Holding down Shift and dragging part marks no longer causes an assert.

Skewed or squashed symbols (with unequal height and width) containing arcs were drawn incorrectly in some cases. This has now been fixed.

The new printing incorrectly displayed a watermark in drawings with the Educational stamp. This has now been fixed.

In shared models, for parametric sketched profiles with several properties, the profile geometries were calculated incorrectly after read in until model was saved and reopened. Now this has been fixed. The geometries are correct after read in. Note that all users of model need have this Service Pack in use when writing out and reading in to have the correct geometries.

Tekla Structures DataSharing facade has been upgraded to version 3.11.19.

The Replace option for importing profiles to the profile catalogcatalog that displays profiles and information on the profiles

In addition to the available profiles in the respective Tekla Structures environment, the user can add fixed or parametric user-defined profiles to the profile catalog. It is also possible to import profiles to the profile catalog.

in shared models now works correctly when cross sections in the original profile and the imported profile have identical names.

synchronization has been improved in situations where the model history contains a lot of deleted objects.

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

Tekla Model Sharing is one of the Tekla online services.

, profile import has been improved as follows:

• Importing of .lis profiles which have double quotes followed by space in the names has been fixed.
• Importing of .lis profiles which have duplicated cross-section points has been fixed.
• Reliability of importing profile updates during read in has been improved.

Previously, the database size could become too large if you created and deleted multiple objects with UDAs. This has now been fixed. 

Performance issues in user-defined sketched profileparametric user-defined profile created in the sketch editor

use have been fixed.

The Diagnose model command now adds a new line "Obsolete object modification rows found." if there are any rows to be removed in the model databasedatabase file that contains a model

Model database file has the extension .db1. In addition, other files, such as the corresponding numbering database .db2, are needed in order to obtain the functionality of the model database.

. Use the Repair model command to remove these rows. This can considerably reduce the database size if it had become too large as a result of creating and deleting multiple objects with UDAs.

Previously, static ID model conversion failed in some rare cases because of ID handling. This has now been fixed.

The contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

The user can customize the contextual toolbar.

The term mini toolbar is used in Tekla Structures until version 21.1.

profiles are now fetched from external environment firm folders along with the users' local profile folder. These external profiles can be loaded in, but any changes will still be saved in the users' local folder as new profiles.

Sometimes Tekla Structures crashed when opening or refreshing a view with polygon reinforcement meshes displayed with the Fast representationthe way that the information included in a model is represented visually

. This has now been fixed.
