2021 SP9: New features, improvements, and important fixes

The latest Tekla Structures service pack and updated environment installers are available in Tekla Downloads.

Drawing mark content text loaded correctly in all languages

Previously, drawing mark setting files containing mark content text (<< Mark >>) did not load correctly when using a different user interface language. This issue has now been fixed, and marks saved in one language can also be loaded in any other user interface language. This fix applies to all part marks, view label marks, dimension marks and tags, and rebar dimension marks.

Examples of mark content text locations:

TTSD-50925

Refresh selected reference models

You can now refresh separately the reference models that you have selected in the reference model list by using the refresh button .

Previously, you could only refresh all reference models.

TTSD-43246

Export ELiPLAN file (68): Exporting sub-materials

You can now export sub-materials of concrete material by using the new Include sub-materials setting on the Data settings tab. Sub-materials have a new section in the data conversion file called #SUBMATERIAL.

For more information about exporting sub-materials, see section "Handling sub-materials in ELiPLAN export" in ELiPLAN.

TSAC-6502

Export Unitechnik (79): Exporting meshes

On the Reinforcement tab, the Export meshes as option Turned to pallet has been renamed to Turned to pallet (longest wire on X axis), and a new Turned to pallet (bent wire on X axis) option has been added to export meshes rotated to pallet plane with bent wires parallel with the X axis of the pallet.

TSAC-6537 Concrete components

Embedded anchors (008): Previously, some anchors could disappear when you had selected to create inclined anchors on the Input tab and the surface where the anchors were placed consisted of two perpendicular planes. This issue has now been fixed.

TPLED-219 Templates and reports

Template Editor: Valuefield formula functions NextValue() and PreviousValue() no longer ignore the sort order when they are used in valuefield formulas. 

TPLED-241 Templates and reports

Template Editor: When a sub-row was filtered out with a rule, the top-level row rule with a CopyField() function could give a wrong result. This issue has now been fixed.

TPLED-243 Templates and reports

Template Editor: A symbol with a rule that used the GetValue function only worked in the first row in the row hierarchy. This issue has now been fixed.

TSAC-6529 Drawings

View-level dimensioning: Drawing dimensioning method Filter performance has been improved in large models. 
NOTE: This improvement changes the guidance we gave earlier when releasing Tekla Structures version 2021 that using a selection filter (.SObjGrp) would be faster than using a view filter (.vf). Now the view filter is faster, and we recommend using only view filters and no longer selection filters.

TTSD-50381 Drawings

Layout editor: Editing sizes in the drawing layout editor works now more reliably.

TTSD-50546 Drawings

Section view labels in drawings no longer disappear when you have changed the section name. Previously, the section view labels disappeared in some rare cases.

TTSD-48039 Tekla Model Sharing

The Project viewer role now uses the same set of permissions as the Carbon configuration.

TTSD-51464 Tekla Model Sharing

If the on-premises server is not accessible, Tekla Structures now reports connection errors more accurately.

TTSD-49885 Reinforcement

Rebar sets: An issue was fixed where the Clear reinforcing bar numbers command, when used with rebar sets, did not flag the numbering of the parent cast unit to be out of date.

TTSD-51123 Reinforcement

Rebar sets: The Diagnose model command now reports Invalid rebar geometry warnings for rebar sets that do not have valid geometry. Previously, rebar set geometry was not checked by the command.

TTSD-51137 Reinforcement

Rebar sets: In unselected rebar sets, the leg faces that are not valid now have appropriate visibility after the Show only selected command has been used.

TTSD-51561 Reinforcement

Rebar sets: Previously, when rebar set layers were edited, Tekla Structures might close unexpectedly. This issue has now been fixed.

TTSD-40910 Modeling

TTSD-47326 Modeling

Snapping issues with cast-in-place concrete parts that are shown as separated have now been fixed.

TTSD-47887 Modeling

Previously, the snap to nearest point and snap to any point snap switches were forced on when the Split command was used. This has now been fixed, and snapping follows the switch settings.

TTSD-48887 Modeling

Previously, very rarely, when copying similar objects which did not belong to any assembly, Tekla Structures might have stopped working. Now, this does not happen anymore.

TTSD-50763 Modeling

An issue in the creation of weld preparations that use edge chamfering could cause Tekla Structures to stop responding or close unexpectedly. This issue has now been fixed.

TTSD-51158 Modeling


Previously, simultaneous autosave for users in a multi-user model did not work correctly because of a file write conflict in the model folders. This has now been fixed.

TTSD-16209 Licensing

Previously, the Role and Configuration fields in the License section of the Settings menu did not show the values defined in the bypass.ini file. Now the fields show the correct values, but you cannot change the values.

TTSD-50598 Licensing

The sign-in browser is shown less frequently when users who are already signed in change from one version or product to another.

TTSD-50071 Installation

The Tekla Structures installer no longer includes the outdated Microsoft Visual C++ 2010 Redistributable Package. Instead, Tekla Structures has been updated to use the newer Visual Studio 2015 + .NET Framework 4.8.

TTSD-51433 Core

The performance of large models has been improved, and the freezing of the model should not happen anymore.

TTSD-50146 Tools and components

The TSEP installer now provides improved logging when a file cannot be installed because the target folder is not writeable or because a file with the same name exists and cannot be overwritten.

TTSD-51635 Tools and components

The handling of invalid or empty *.tsep files has been improved in the TSEP File Dispatcher. Previously, double-clicking an invalid file could cause the application to become unresponsive. Now, a message is shown to inform the user that the file is invalid.

TTSD-51411 Numbering

Previously, in some situations, parts with different contour marking were not numbered differently. This issue has now been fixed.

TTSD-49537 User interface

Previously, when selecting the Open button and then the All models tab on the start screen, texts were overlapping. Now, the popup text of the Open button on the start screen closes automatically when the mouse cursor is moved to the start screen tabs area.
 

TTSD-51056 Import, export, interoperability (steel)

NC/DSTV: Earlier, in the DSTV export of bent plates, the XS_USE_NEW_PLATE_DESIGNATION advanced option affected the AK block and header, but not the KA block. This issue has now been fixed.

TTSd-51310 Import, export, interoperability (steel)

NC/DSTV export: Earlier, when a part was presented twice in the bolt connection, bolt holes were missing from the export to DSTV. This issue has now been fixed.
