Fixes

Defect number Development area Description
TSAC-138 Concrete components In Wall to wall connection and Wall groove seam detail, the connector and recess spacing now work properly when other than millimeter units are used.
TSAC-1656 Concrete components In Floor layout, an extra part was previously created at an opening. This has now been fixed.
TSAC-1684 Concrete components In Floor layout, the default/actual offsets of other layers than the primary layer now work properly also when other layers consist of multiple parts, and the offset is smaller than the offset of the primary layer.
Note that if you are modifying an existing Floor layout created with a previous Tekla Structures version, the layout may change if the offset values were not properly used earlier.
TSAC-1749 Concrete components In Mesh bars and Mesh bars by area, when you set the secondary bars to Same as primary and the bar type to Mesh on the Picture tab, the Spacing and Number of bars settings are now correctly dimmed.
TSAC-1754 Concrete components In Mesh bars, line cuts now work correctly when the Cut bars setting on the Detailing tab is set to Yes, but ignore cuts by name.
TSAC-1778 Concrete components In Wall layout, you can now again open the Wall layout opening dialog box from the contextual toolbar.
TSAC-1947 Concrete components In Hollow core lifting loops, the core filling was not created in the middle core if the number of cores was uneven, 5 or 7, for example. This has now been fixed.
TSAC-2004 Concrete components In Mesh bars, direct modification now works correctly so that the correct bar is moved when dragged.
TSAC-2120 Concrete components In Sandwich and double wall, there is now a new Foil tab for controlling the vertical and/or horizontal splitting of the foil.
TSAC-2134 Concrete components Lifting anchor (80) now works correctly for elements created from concrete and miscellaneous materials.
TSAC-2152 Concrete components Previously, Floor layout updating was not working properly if the layout had a break line and the layout direction was from right to left. This has now been fixed.
TSAC-2231 Concrete components In Wall layout, when customizing the content of the UDA tab, you can now define in the WallLayout.Udas.dat file that layer UDA values are not swapped when the Wall layout swapper is used. You can do this by adding NoSwap at the end of the line (fourth field):
string comment j_comment NoSwap
TSAC-2251 Concrete components Floor layout now creates additional tabs for user-defined attributes in the Floor layout dialog box if there are a lot of user-defined attributes. Earlier, if there were a lot of user-defined attributes, the row spacing on the User defined tab was compressed to fit all the attributes on one tab.
TSAC-2326 Concrete components In Corbel connection (14), the console is now not created if you select the input parts in the wrong order.
TSAC-647 Concrete components In Mesh bars by area, dragging a polygon edge no longer takes its boundary out of the plane.
TSAC-1489 Steel components In Two sided clip angle (143), web clearance with the weld gap option on the Parts tab now works correctly.
TSAC-1809 Steel components In Two sided clip angle (143), it is now possible to sort the secondary parts by their profile height. When set to Yes, the highest secondary part is always regarded as the first secondary part, regardless of the selection order.
The selection order of secondary parts no longer affects the copying of secondary parts.
TSAC-1875 Steel components In Column - 2 beam (14), there were previously issues when you created one plate and the bolts were placed incorrectly. This has now been fixed.
TSAC-2079 Steel components In Handrail 1 (74), the bolt assembly and bolt length increase settings on the Bolts tab now work correctly.
TSAC-2111 Steel components In Stanchion side plate (83), you can now set the bolt spacing when creating a rectangular or a diamond plate.
Also, the component now works correctly when the direction if set to auto.
TSAC-2124 Steel components In Tube gusset (20), the end plates are now created correctly.
TSAC-2133 Steel components In Tube crossing (22), the spacing between two connection plates now works correctly.
TSAC-2159 Steel components In End plate (29), stiffener material is now correctly applied.
TSAC-2369 Steel components In Corner tube gusset (56), you can now separately control the bolt types of Brace bolts 1 and 2 on the gusset side and the bracing side.
TSAC-253 Steel components

In Column with stiffeners S (187), the bolt edge distance is now correctly applied with sloped beams.

TTSD-13621 Steel components When using Excel design with connections, if the .xls file is not found, the error message is no longer hidden behind other windows on the screen.
TTSD-18533 Organizer Previously, opening Organizer in models that included very large assemblies took a long time or was altogether impossible. This has now been fixed.
TTSD-19256 Organizer In Organizer, the content of categories that have filters in the category rules is now updated correctly when synchronizing with the model. Previously, if you exploded a component in the model, the category content was not updated correctly.
TTSD-12817 Import, export, interoperability The user-defined attributes added in Tekla Structural Designer are now imported to Tekla Structures with the same name, without the "TSD_" prefix, and they are truncated to 19 characters.
TTSD-15599 Import, export, interoperability In reference model change detection, the reference model rotation changes are now detected better.
TTSD-15682 Import, export, interoperability Spaces can now be used in IFC object conversion profile mapping. They are removed in internal mapping. For example, UB 356x171x45 finds UB 356x171x45, not UKB356x171x45, like previously.
TTSD-15953 Import, export, interoperability In IFC object conversion, WallStandardCase is again converted as panel. End joins are ignored and therefore the geometry is not always according to the original geometry.
TTSD-16610 Import, export, interoperability Trimble Connector no longer automatically shuts down at startup if you have no Trimble Connect Structural license.
TTSD-17389 Import, export, interoperability In  IFC change detection, selecting from the changes list and from the model view has been improved. Previously, you could not select a deleted object and a newer inserted object.
TTSD-17672 Import, export, interoperability .db1 models can now be used as reference models again.
TTSD-17891 Import, export, interoperability In IFC object conversion, rectangular arbitrary footprint walls are again converted as panels.
TTSD-18633 Import, export, interoperability When you removed a reference model version and did not click Modify, and then added a new version, the reference model version handling was broken. Now when you remove a version, you are asked if you want to set the model as current and save changes.
TTSD-19481 Import, export, interoperability The performance of locking and unlocking multiple reference models in the reference model list has been improved.
TTSD-19976 Import, export, interoperability In IFC import, handling of objects with a lot of openings was really slow, which appeared like Tekla Structures was not responding. This has now been fixed.
TTSD-20194 Import, export, interoperability Importing an empty model using the Import model command caused an application error. This no longer happens.
TTSD-20456 Import, export, interoperability In DWG/DXF export, when adding, editing or deleting multiple rules, the buttons are now always visible. Previously they would not be visible with multiple rules if the list of rules was scrolled down.
TTSD-20988 Import, export, interoperability When you cancelled the drawing opening, opening the reference model side pane in certain moment caused freezing of the reference model side pane. This has now been fixed.
TTSD-21526 Import, export, interoperability Trimble Connector no longer logs out when it is closed.

TTSD-7136 Import, export, interoperability Tekla Structures now shows a confirmation message when you delete shapes from the shape catalog.
TPLED-111 Templates and reports Tekla Structures no longer crashes with horizontal column output in templates.
TPLED-70 Templates and reports Previously, the CopyField formula copied the first output value and not the last when used in a page footer or footer. This has now been fixed.
TPLED-84 Templates and reports Rows are no longer overlapping when you use Right alignment.
TPLED-87 Templates and reports When the columns in a template had continuous horizontal fill, the rows and columns were misaligned. This has now been fixed
TPLED-97 Templates and reports Template Editor: The Extend command is working again.
TSAC-1247 Drawings Rebar group marking: On the Mark 3 tab you can now define how to rotate the mark text using the new setting Mark rotation. You can rotate the mark text horizontally, vertically or to the mark line direction (default).

TTSD-10813 Drawings When cloning single part, assembly or cast unit drawings, if the cloning template had views which were aligned in X or Y axis at the center of gravity point, the resulting cloned drawing will now try to align matching views based on the center of gravity.
TTSD-16747 Drawings When you create several drawings at a time, Tekla Structures shows a progress dialog with a Cancel button. However, clicking the Cancel button did not stop creating new drawings, but created them without templates. This has now been fixed. Moreover, now the dialog box also shows two progress bars: the first bar shows what is done for each drawing, and it goes back and forth. The second bar proceeds steadily after every drawing.
TTSD-17987 Drawings Sometimes, the dimension line was drawn incorrectly between the dimension points. This has now been fixed.
TTSD-18347 Drawings Weld marks in drawings that had the size hidden in the weld mark properties were not drawn correctly. This has now been fixed.
TTSD-18511 Drawings You need to set the advanced option XS_TRY_TO_KEEP_LOCATION_IN_FREEPLACING to TRUE (Default) for the advanced option XS_MARK_INTELLIGENT_POST_FREEPLACE_NEARBY to work.
TTSD-18695 Drawings Symbols in some dimensions and labels did not appear in printed output. This has now been fixed.
TTSD-18705 Drawings Sometimes closing a drawing while the snapshot viewer was open, and then closing the snapshot viewer could cause an ASSERTion failure or even a crash. This has now been fixed.
TTSD-18742 Drawings Views in assembly drawings that contain included single-part views are no longer overlapping after the Arrange views command.
TTSD-19304 Drawings If a dimension that did not have the << Mark >> tag but had some properties set in the tag attributes, changing the dimension via the contextual toolbar was adding an unwanted tag mark to the dimension. This has now been fixed.
TTSD-19359 Drawings Dimension arrows indicating a change in the model object extremes are no longer exported.
TTSD-19516 Drawings Marks sometimes lost the Position element when you used mark alignment tools in drawings. This has now been fixed.
TTSD-19579 Drawings In Tekla Structures version 2018, scrolling with the middle mouse button while editing some drawings sometimes caused a Tekla Structures application error. This has now been fixed.
TTSD-19613 Drawings When updating drawings from an older Tekla Structures version to a newer version, certain view names could causes crashes, for example, names that ended in a % character. This no longer happens.
TTSD-19684 Drawings Tekla Structures sometimes crashed when you modified protection settings and items were selected in the Drawing content manager. This has now been fixed.
TTSD-19690, TTSD-18337 Drawings When a point was removed from a dimension set, pin icons on the remaining dimension points could incorrectly show that the points are no longer associative by changing to question marks, while the points still were associative. This has now been fixed.
TTSD-19718 Drawings Drawing view scales were incorrectly modified when the Autoscale option was changes from Yes to No. This happened only with new drawing dialog boxes. This has now been fixed.
TTSD-20204 Drawings In some cases, an assert was caused by a missing symbol library. This has been fixed, and an error message is displayed instead.
TTSD-20209 Drawings Tekla Structures crashed when you changed the ruler width of a text with handle. This has now been fixed.
TTSD-20407 Drawings Opening of some drawings could sometimes fail. This has now been fixed.
TTSD-4111 Drawings

Previously snap settings in drawings were saved only if you saved the drawing through the File menu. The settings were not saved if you saved the drawing by closing the drawing and selecting the Save option. Now snap settings are saved properly in both cases.

TTSD-18318 Tekla Model Sharing Previously, Tekla Structures occasionally crashed in certain Tekla Model Sharing situations, with warning messages about an unknown user. This has now been fixed.
TTSD-18762 Tekla Model Sharing Previously, Tekla Model Sharing would sometimes fail to initialize when opening a shared model, with the following error message in the DataSharing client log: "DataSharingException: Facade is not connected to service.". This error has now been prevented.
TTSD-19624 Tekla Model Sharing Previously, Tekla Model Sharing file handling could copy temporary files to another model, which could make history reading and writing to report database corruption. Now this has been fixed. Such files are never written out and not read during read in.
TTSD-19701 Tekla Model Sharing When joining a shared model, Tekla Model Sharing now checks if the current system locale is compatible with the system locale that was used when the model was shared. This check helps to avoid issues when distributed teams are using the model. Tekla Structures is not a fully Unicode application and it may function incorrectly when a shared model is opened with a system locale that is incompatible with the one that was used when starting to share the model.
TTSD-21393 Tekla Model Sharing With some reference models, the changes list in a shared model could open very slowly. This has now been fixed.
TTSD-6851 Tekla Model Sharing Saving of shared models is now more robust than before in situations where antivirus and similar software put temporary locks on model files. Failed operations are retried and written in error logs.
TTSD-16829 Reinforcement Previously, rebar adaptivity would break in some cases, especially if the concrete object had very small angles between the faces.
TTSD-12525 Modeling When you create new pour breaks, they are now added to the current phase.
TTSD-15116 Modeling When using orthogonal snapping, the snap points are now shown with perpendicular snap symbols.
TTSD-16464 Modeling Modifying the phase of objects now redraws the objects in the correct color when the Color by phase option is used in the object representation settings. Previously, the color of the objects did not change when modifying the phase.
TTSD-17093 Modeling In the property pane, you can now save and load bolt assembly property files that only contain the bolt but no other parts in the assembly.
Note that if you select or clear the Bolt check box in the bolt assembly properties, the check boxes for Washers and first Nut properties are also selected or cleared, as in the old bolt properties dialog box.
TTSD-17733 Modeling The Add to pour unit and Remove from pour unit commands are now visible on the context menu to more combinations of selected objects when right-clicking.
TTSD-17915 Modeling Sometimes, opening an older Tekla Structures model with a newer Tekla Structures version resulted in invalid time ID errors, and the model could not be opened. This has now been fixed.
TTSD-17941 Modeling Steel embeds are now ignored when calculating AREA_FORM properties.
AREA_FORM properties require solid unions to be used. Small steel embeds can cause problems when creating solid unions, and they do not have a lot of effect on the end result.
TTSD-18600 Modeling When saving the model with Save as, the model name is now restricted to 40 characters, like when creating a new model. The last 10 model paths are not shown in the Save as dialog box.
TTSD-18604 Modeling Filtering based on OWNER or HISTORY.OWNER now works with both <DOMAIN>/<username> and <DOMAIN>\<username>.
TTSD-18763 Modeling Previously, some important messages were classified incorrectly as debug information. This has now been fixed.
TTSD-19562 Modeling Filtering assemblies by user-defined attributes now again searches attributes from the assembly's main part.
TTSD-20604 Modeling The saving of multi-user models has been improved to work more reliably.
TTSD-20700 Modeling Previously, saving the model with Save as failed in some situations and Tekla Structures displayed the message Model memory is corrupted. This has now been fixed.
TTSD-20921 Modeling Filtering reinforcing bars by using 'length' now works correctly again.
TTSD-21032 Modeling You can now clear assembly and cast unit numbering properties in the assembly and cast unit property pane to inherit the values from the steel and concrete part level.
TTSD-21482 Modeling Previously, if you left Tekla Structures idle for a while, in some cases Tekla Structures could freeze or crash. This has now been improved.
SOLD-783 Licensing When starting Tekla Structures for the first time, and the license server has not been defined, the waiting time has been significantly reduced from around 3 minutes down to about 30 seconds.
TTSD-12559 Analysis and design Previously, if you had created a rigid link between analysis nodes, you could not move or merge nodes that had been created manually. This has now been fixed.
TTSD-12971 Analysis and design When importing changes from Tekla Structural Designer to Tekla Structures, you can now rotate the model when the Model Comparison Tool dialog box is open.
TTSD-13158 Analysis and design Previously, slab and panel hole analysis node positions were not created in the correct plane. This has now been fixed.
TTSD-13552 Analysis and design When changing the analysis part class to Secondary or Bracing, the Keep axis position option is now set to No. Also, when changing the class to Beam or Column, the Keep axis position option is set to Yes. Note that if you set the analysis application to Tekla Structural Designer and the class to Beam, the Keep axis position option is not changed to Yes.
TTSD-14412 Analysis and design In the analysis model properties, the Curved beam property is now set to Use curved member when creating a new analysis model with the Tekla Structural Designer analysis application, or when changing the analysis application of an existing analysis model to Tekla Structural Designer.
TTSD-16487 Analysis and design The Finland environment and the Norway environment now include localized conversion files to be used as the default conversion files in the import and export between Tekla Structures and Tekla Structural Designer.
TTSD-17063 Analysis and design When importing and exporting files between Tekla Structures and Tekla Structural Designer, if your environment includes a conversion file localized for your environment, this file is now used as the default conversion file, instead of the global mapping files.
TTSD-17940 Analysis and design You can now export circular concrete columns to Tekla Structural Designer when using the US imperial environment.
TTSD-19340, TTSD-17940 Analysis and design Concrete columns and beams with parametric profiles, for example 36"*36" and D24", are now correctly exported from Tekla Structures to Tekla Structural Designer.
TTSD-19862 Analysis and design Split nodes are now created correctly in situations where the analysis part positions change in analysis model creation.
TTSD-19916 Analysis and design Concrete panel analysis connectivity has now been improved.
TTSD-5810 Analysis and design Staad export from Tekla Structures now takes into account the new XS_AD_LOAD_COMBINATION_METHOD advanced option.
The possible values are:
0 = use repeat load
1 = use load combination (if linear analysis method is used)
TTSD-19981 Core When you tried to change the advanced option XS_​DRAWING_​PLOT_​FILE_​NAME_​W in Russian language, Tekla Structures crashed. This has now been fixed.
TSAC-932 Tools and components In Radial array tool, angle values with decimals are now supported in regional settings.
TTSD-16347 Tools and components Previously, when you edited a custom component, then closed the custom component editor dialog box and applied the changes to the custom component instances in the model, a copy of the custom component appeared in the model if any of the component instances had locked parts. Now the extra copy is always removed from the model.
TTSD-17873 Tools and components Previously, in some cases, Tekla Structures could crash at start up when launching external tools. The crash is now prevented. The timing for the external tools is still the same, and as before, they still try to run before the model is open.
TTSD-18588 Tools and components Custom components containing system components were not correctly created when creating several custom components within one command sequence. This has now been fixed.
TTSD-19715 Tools and components Previously, closing Tekla Structures after model loading failed could cause Tekla Structures to crash. This has now been fixed.
TTSD-20007 Numbering When you use standard-part models in numbering, the standard parts now get the start number of the oldest standard part in the actual project model, instead of a random number.
The start number cannot be used to divide identical standard parts in groups, as the parts all get the same part position, prefix, and start number.
SOLD-618 User interface In the Support tool, while you create the support case, the navigating back button in the upper-left corner is disabled for a moment so that you cannot accidentally interrupt the upload.
SOLD-722 User interface Staying signed in to Tekla Structures now works correctly. Previously, when logging in to Tekla Structures, in some cases the option to stay signed in did not work correctly or it was not available at all.
TTSD-18464 User interface You can now use 2-byte Japanese characters, as well as other multi-byte characters, in the search box in the Tekla Online side pane.
TTSD-19192 User interface In some cases, copying properties in the property pane did not work. This has now been fixed.
TTSD-19949 User interface The bolt group distance x and distance y settings in the property pane are now properly updated when loading a property file.
TTSD-20068 User interface

The

TTSD-20802 User interface Several fixes have been made to DirectX graphics including improved performance for the shaded wireframe (Ctrl/Shift+2) view mode.
TTSD-20918 User interface Previously, saving the model with Save as could cause Tekla Structures to crash and restart instead of exiting. This has now been fixed.
TTSD-21403 User interface The cast unit numbering series in the concrete part property pane is now shown as dimmed if it is changed in the cast unit level.
TTSD-9042 User interface In the assembly, cast unit, and pour property pane, the name, prefix, and start number that are defined automatically based on the main part are now shown in brackets [ ]. This is consistent with the old property dialog boxes.
