2021 SP1: New features and improvements

Tekla Structures start screen now shows organization name

Tekla Structures start screen now shows your organization under the information about your current Tekla Structures setup.


Splitting plates and slabs

The Split command on the Edit ribbon tab has been improved, and it is now easier to split contour plates and slabs in the model. You no longer need to use a polygon for splitting, or shift the work plane.

To split a plate or slab:

  1. On the Edit tab, click Split.

  2. Select the plate or slab you want to split.

    Bent plates and lofted plates and slabs cannot be split.

  3. Pick the points you want the splitting line to go through.

    Pick the first point and the last point on an edge of the plate or slab.

    Areas with chamfers, cuts, or openings cannot be split. If you try to pick points in these areas, the preview of the splitting line turns red, indicating that splitting is not possible.

The Split plate or slab command that was available in Quick Launch in Tekla Structures 2021 has now been removed and combined with the Split ribbon command.


Document manager UDA search

Document manager now searches for DocumentManagerUDAs*.txt files recursively in extension folders and subfolders in addition to the previously available search locations.

The DocumentManagerUDAs*.txt files define the drawing UDAs that are shown in the Document manager columns.


Texts in PDF reference models

PDF reference models now have better coverage for texts.


Layers in .tekla models

Layers are now available for objects in .tekla models. To upload a .tekla model with layers to the linked Trimble Connect project, you need to customize the part.epr file:
  1. Copy the part.epr file from the \TeklaStructures\<version>\Environments\common\system\UploadToConnect folder to the \attributes folder under the current model folder.

  2. Open the part.epr file in a text editor, such as Microsoft Notepad.

  3. Add a line for layers in the following format: "layer": ["TEMPLATE_FIELD"]

    For example, "layer": ["ASSEMBLY_POS"]

  4. Save the part.epr file.

Improvement in IFC export property sets

The IfcRoof, IfcRamp and IfcStair property set definitions could not be included in the IFC export without including the IfcElementAssembly as well. This has now been fixed.


New control for forcing IFC object category in IFC2x3 export

The IFC2X3 export does not export steel secondary objects as IfcDiscreteAccessory from now on. You can force previous categorization by setting the new advanced option XS_IFC2X3_EXPORT_SECONDARY_AS_DISCRETEACCESSORY to TRUE in an .ini file, for example, teklastructures.ini.


Improvements in concrete components

Embedded anchors (8)

On the Placement tab, you can now select whether to detect braced girders in the whole assembly.


Beam reinforcement (63)

On the Parameters tab, you can now select to create side bars as rebar groups. Previously, all side bars were created as separate single bars.


Concrete console (110)

On the Parameters tab, there is a new column cut-out type for T-shaped secondary parts. Using this new cut-out type, you can now add an additional cover thickness between the column and the beam.


Wall panel reinforcement / Double wall edge and opening reinforcement

Bent mesh settings have the following improvements on the Picture tab:

  • Longitudinal overhangs

    Select Target to create variable overhang lengths. This creates meshes as full length meshes minus the cover thickness.

    Select Exact to create centered meshes with a fixed overhang length.

  • Minimum gap

    Define the gap between the meshes in the corners.
