TTSD-15615 Drawings Previously, if XS_ENABLE_REBAR_MARK_LEADER_LINE_BASE_POINT_OPTIMIZATION was set to TRUE, Tekla Structures optimized the base point location after you manually dragged the base point into different location. Therefore, in some cases, the base point would move to a different location than the location you dragged it to.
TTSD-15835 Drawings In drawing DWG export, you can now use UDAs in the plot file name.
TTSD-16127 Drawings When pours were used as neighboring part in a drawing, settings for the main pour were overriding settings used for neighboring parts when modifying the drawing. Now Modify keeps and updates properties of pours as neighboring parts to correct values.
TTSD-16188 Drawings When you added a level mark using the command Add level mark, the mark was placed in an incorrect location. This has now been fixed.
TTSD-16192 Drawings Now the non-solid breps which are partially cut by a view are not shown in drawings because the resulst are not satisfactory in certain cases. Non-solid breps which are fully inside a view are shown.
TTSD-16199 Drawings Dimension arrows were drawn to both ends of absolute dimensions. Now this has been fixed, and the dimensions are again drawn correctly to one end only. If the symbol does not have a direction, then it is drawn to both ends.
TTSD-16359 Drawings Subassemblies did not get position dimensions in assembly drawings. This has now been fixed.
TTSD-16411 Drawings The origin of the hatch in polygons with a rotated hatch pattern was incorrectly calculated. This has now been fixed.

TTSD-16648 Drawings Starting from 2018 version, radial dimension arrow symbols were following the dimension symbol style that was defined for general dimension symbols. Radial dimension arrow symbols can now only be set to arrow type symbols.
TTSD-16659 Drawings Previously, in some cases, opening a drawing caused Tekla Structures to crash. This has now been fixed.
TTSD-17026 Drawings Before when you created cast unit or assembly drawings using a filter, view level dimensioning produced dimensions for cuts even if the cut part was filtered out. This has now been fixed.
TTSD-17069 Drawings A memory leak occurred at drawing opening when you had set the advanced option XS_HIDDEN_LINES_UNHIDE_EMBEDDED to TRUE. This has now been fixed.
TTSD-17148 Drawings Sometimes Tekla Structures application error occurred when you had set Show openings/recess symbol to Yes in drawing view properties and you opened a drawing of a curved structure. This has now been fixed.
TTSD-17238 Drawings In some cases, using filters in drawings would incorrectly filter out grids. This has now been fixed.
TTSD-17249 Drawings Connection marks sometimes lost some of their elements when the Arrange marks and Align marks commands were used. This has now been fixed.
TTSD-17274 Drawings Tekla Structures sometimes crashed when you used the Adjust location option for a group of curved rebars. This has now been fixed.
TTSD-17432 Drawings Previously, Tekla Structures unintentionally changed some view properties when the view settings on the drawing level were modified. This has now been fixed.
TTSD-17436 Drawings Views inside the single-part views were incorrectly modified when the layout of the assembly drawing was changed. This has now been fixed.
TTSD-17439 Drawings If an existing single-part drawing is included in an assembly drawing, the view placing inside the single-part drawing container frame no longer changes if you run the Arrange drawing views command in the assembly drawing.
TTSD-17454 Drawings Column marks in the US environments are now placed better by default.
TTSD-17485 Drawings Previously, single-part drawings did not contain any dimensions if XS_ASSEMBLY_POSITION_NUMBER_FORMAT_STRING contained part UDAs. This has now been fixed.
TTSD-17577 Drawings Educational license: previously, you could not export assembly drawings to a DWG file. This has now been fixed.
TTSD-17601 Drawings Rebars with outline representation are now drawn on top of hatches like other rebar representation types.

TTSD-18007 Drawings

Previously, drawing views could get corrupted when moved from one drawing to another. This has now been fixed.

Also, some curved lines with a very big radius could change to straight lines in drawings when custom presentation was used, or when printing drawings.  This has now been fixed.

TTSD-18468 Drawings The size of the detail views that were moved to another drawing was not adjusted correctly. This has now been fixed.
TTSD-18851 Drawings Custom line types did not always work correctly, for example, in arcs. This has now been fixed.
TTSD-18949 Drawings When deleting obsolete drawing .dg files, a backup of related snapshot files (.dg.DPM) was unnecessarily moved under the \snapshots folder under the current model folder. This no longer happens.
TTSD-8361 Drawings Sometimes rebar mesh mark could be created to an incorrect location, especially for bent meshes. This has now been fixed.
TTSD-9467 Drawings Shortening line color was incorrect in the print output. This has now been fixed.
TTSD-16923 System and options Previously, if you set the autosave interval less than 2, autosave was disabled. This has now been changed so that the smallest accepted value for the autosave interval is 2, both for modeling and for drawings.

If you try to enter a value smaller than 2, Tekla Structures automatically changes the value to 2.
TTSD-14133 Tekla Model Sharing In Tekla Model Sharing, components added to the Applications & components catalog were not visible in the correct place and thumbnails were now shown in the catalog when shared. This has now been fixed.
TTSD-14342 Tekla Model Sharing In Tekla Model Sharing, in cases where several users concurrently defined parametric profiles with variable cross sections and the changes were read in, the parts that were using variable cross section profiles were modified in the local models.
This service pack now fixes this issue. We recommend that all users of a shared model use the same Tekla Structures service pack when working with the model.
TTSD-15209 Tekla Model Sharing Previously, some profiles were not imported correctly, which caused issues, such as unexpected object updates, in Tekla Model Sharing. This has now been fixed.
TTSD-15719 Tekla Model Sharing In a shared model, locked components are now better handled during read in. Previously, there were issues with locked components that should have been updated during read in because of changed component definitions. Now such components are not updated during read in. The modelsharing.log lists these components and the reason why they were not updated.
TTSD-15860 Tekla Model Sharing An issue that could cause Tekla Structures to crash while using Tekla Model Sharing with a model that contained pours and pour breaks has now been fixed.
TTSD-16071 Tekla Model Sharing In Tekla Model Sharing, read in previously failed if two incoming files with different names were changed to have the same name after Unicode Compatibility Decomposition normalization. Such files could be ascii symbols and corresponding fullwidth symbols. Now Tekla Structures reads in such packages and tracks both, or more, such clashing files.
TTSD-16253 Tekla Model Sharing Certain Unicode characters in file names (such as, Kelvin symbol 'K') caused the Tekla Model Sharing write out to fail. This has now been fixed.
TTSD-18420 Tekla Model Sharing In a shared model, when reading in, conflicts in part numbering were not always propagated to the assembly, which left the assembly numbering unchanged. This has now been fixed.
TSAC-1648 Reinforcement Rebar shape manager now shows rebar shapes correctly. Previously, certain shapes were recognized as curved even if the shape was a normal polygonal shape.
TTSD-15782 Reinforcement In rebar sets, when splitters are used, the lapping side is now kept consistent throughout the whole rebar set.
TTSD-16635 Reinforcement In the property pane for rebar set property modifiers, if you selected the bending radius from the list, the value was marked as invalid. This has now been fixed.
TTSD-17083 Reinforcement Object representation settings now again work for rebar sets.
TTSD-17173 Reinforcement Rebar sets can now be selected by clicking on a row in a report that contains a GUID and a "GUID:" label. Use the selection switches to control your selection: Select single rebars to select an individual rebar, Select rebar groups to select a rebar group, and Select rebar sets to select rebar sets.
TTSD-18209 Reinforcement Previously, Tekla Structures sometimes crashed when you selected some rebar groups, then right-clicked and selected Show only selected. This has now been fixed.
TTSD-18311 Reinforcement Previously, when a rebar set with modifiers or splitters was copied, its UDAs were not copied with it. This has now been fixed.
TTSD-15088 Modeling PHASE.NAME for rebars now returns the name of the rebar phase. Previously, PHASE.NAME for rebars returned the name of the father part phase.
TTSD-15232 Modeling Previously, Tekla Structures displayed an error message in the sketch editor when you used the keyboard to enter a position. This has now been fixed.
TTSD-15234 Modeling Previously, modeling sketches in the sketch editor could cause an error, and an error message was shown. This has now been fixed.
TTSD-15293 Modeling Previously, very complex interaction of multiple objects with multiple cuts caused Tekla Structures to crash if you modified the model in the multi-user mode and set XS_ENABLE_POUR_MANAGEMENT to TRUE, and then saved the model. This happened at least in the SE Asia environment. The issue has now been fixed.
TTSD-15369 Modeling When cast-in-place concrete parts are hidden or made transparent with the Hide or Show only selected command, the pours made of the parts now stay hidden/transparent when changing the view setting to pour view. Also, when using the Hide or Show only selected command on a pour object, their cast-in-place parts now stay hidden/transparent when switching from pour view to part view.
TTSD-15833 Modeling Umlaut and multi-byte characters in item properties are now supported when importing Tekla Warehouse items to Tekla Structures.
TTSD-16278 Modeling Using the Show only selected command on a pour unit now shows the rebar set rebars in the selected pour unit only. Previously, if there were multiple pour units containing rebar sets and you selected and used Show only selected on one of the pour units, all rebars were shown, even those that were not in the selected pour unit.
TTSD-16717 Modeling Using the Hide command on a pour unit now hides the rebar set rebars in the selected pour unit only. Previously, if there were multiple pour units containing rebar sets and you selected and used Hide on one of the pour units, all rebars were hidden, even those that were not in the selected pour unit.
TTSD-16833 Modeling Previously, the rebars in a rebar set did not appear in a GA drawing if the bar group spanned a pour break. This has now been fixed.
TTSD-16860 Modeling Previously, Tekla Structures could crash when splitting polygon plates. This has now been fixed
TTSD-16906 Modeling There is a new template attribute ADDED_TO_POUR_UNIT to indicate how an object was added to a pour unit.
The possible values are:
0 - unassigned and dirty (modified after the pour unit was resolved the last time)
1 - manually assigned
2 - automatically assigned

The attribute is in the template category in filters and in the template attributes for the following object types:
ASSEMBLY
BOLT
CAST_UNIT
(only precast, not for cast in place)
MESH
REBAR
SINGLE_REBAR
SINGLE_STRAND
STRAND
STUD
TTSD-17029 Modeling The naming conventions of the 3D products in Tekla Warehouse have been improved.
The naming now complies with the following scheme:
3D product name in Tekla Warehouse = Item name shown in the property pane in Tekla Structures
3D product code in Tekla Warehouse = Component name shown in the Applications & components catalog
Geometry file name (without extension) = Shape name shown in the Shape Catalog dialog box
TTSD-17261 Modeling Previously, saving the model sometimes failed after a reference model was deleted. This has now been fixed.
TTSD-17561 Modeling Previously, there were some issues in the profile and material catalog export and import, and in editing rules in the profile and material catalog. This has now been fixed.
TTSD-17582 Modeling Previously, the Move linear command did not move objects which were selected with Object by phases in Phase Manager. Only the grid that was included in the phase was moved.

Now, if the grid is the only selected object, it is moved. If also other objects are selected, such as parts, bolts, welds and so on, the grid does not move but the other objects move.
TTSD-17603 Modeling You can now enter more than one line of Reference text for welds in the property pane.
TTSD-17652 Modeling Now the custom component formulas no longer require an extra click to update another value.
TTSD-18267 Modeling POUR_UNIT. template attributes now work with all mesh types.
TTSD-2031 Modeling You can now define the size of both welds in compound welds. In weld properties in the property pane, two boxes for Size appear when you select a compound weld type.
TTSD-15575 Licensing The performance of Tekla Structures learning edition installation and Tekla Structures Partner installations has been enhanced.
SOLD-606 Installation The performance of the Partner installation has been improved.
TTSD-12633 Analysis and design You can now report rigid links with the new ANALYSIS_RIGID_LINK content type. The following template attributes are available: CONTENTTYPE, ID, GUID, ANALYSIS_MODEL_NAME, TYPE, and LENGTH. The template attributes are not available through the Open API interface.
TTSD-12766 Analysis and design Polybeam chamfers are now handled as analysis model nodes and members.
For chamfer curves, polyline approximation use depends on the analysis model properties (which can be overridden for parts) as for normal curved beams.
TTSD-15004 Analysis and design Previously, analysis node numbers were drawn on top of each other or too far from the node. This does not happen anymore. The numbers of the selected nodes now have the magenta color.
TTSD-15023 Analysis and design Connectivity logic has been improved for bar to bar connections when the selected analysis application is Tekla Structural Designer.
TTSD-15111 Analysis and design Twin profiles, such as double angles, are now exported correctly from Tekla Structures to Tekla Structural Designer when exporting the analysis model with the physical model.
TTSD-15629 Analysis and design New load groups are now correctly added to the Load Combinations dialog box when a load group is modified.
TTSD-15786 Analysis and design In some situations, after deleting rigid links from the analysis model, the rigid links reappeared when rebuilding the analysis model.
TTSD-16373 Analysis and design Incremental analysis model update has been improved to reduce the need for rebuilding the analysis model.
TTSD-18396 Analysis and design Analysis node positions are now correct when using Reference axis (eccentricity by neutral axis) as the analysis axis position. Also, when inquiring analysis parts, the offsets are now shown correctly.
TTSD-4757 Analysis and design Exporting polybeams from Tekla Structures to Tekla Structural Designer is now possible with certain limitations. The export to Tekla Structural Designer uses the correct analysis position, but the exported alignment may not always be correct, i.e. the physical position in Tekla Structural Designer may not match the physical position in Tekla Structures.
TTSD-13213 Core In some cases, the info and warning status of log messages was switched. Now log messages are more correctly classified as warning or info messages.
TSAC-590 Tools and components Linear array tool and Radial array tool now correctly create duplicates when copying other array tool components.
TTSD-16497 Tools and components Translation of custom component names is now enabled in the Applications & components catalog. The names should not contain special characters or spaces for translation to work correctly.
In the .ail file used to translate the custom component name identifier of string should use this format:
"albl_" + custom component internal name
For example, if the custom component name is "MyCustomPart", in the  .ail file it should start with:
string_utf8 albl_MyCustomPart
{
    entry = ("enu", "My Custom Part");


TTSD-14900 Numbering

Previously, starting from Tekla Structures 21.1, the number of an unmodified part might change if another part became exactly the same in terms of numbering. In numbering, the unmodified part received the same number as the modified part.
Now, if both the modified part and the unmodified part have or do not have drawings, the unmodified part will keep its number. If one of the part has a drawing and the other one does not, the number of the part that has a drawing will stay the same, and the number of the part that does not have a drawing will change.

TTSD-17597 Numbering If assembly numbering series has been defined in the assembly properties, property pane no longer allows you to modify the assembly numbering in the part properties.
TTSD-16048 User interface Now buttons that launch a macro or a plugin are properly enabled on customized drawing ribbons.
TTSD-16108 User interface The property pane now shows the properties of steel items when assembly selection is activated.
TTSD-17373 User interface The property pane now shows the corner chamfer dimension units according to Tekla Structures unit settings.
TTSD-17844 User interface Previously, when you cleared a value in the rebar set spacing zone properties in the property pane, clicking Modify caused Tekla Structures to crash. Now the property pane automatically validates the data in the spacing zone properties and you cannot click Modify anymore.
TTSD-18352 User interface Previously, the area selection cursor did not work correctly with the latest NVIDIA drivers in OpenGL views. This has now been fixed.
TSAC-1476 Import, export, interoperability (steel) Sometimes, some bolt holes were missing from the NC data. This has now been fixed.
TSAC-1223 Import, export, interoperability (concrete)

Export EliPlan file (68): It is now possible to export elements with ACN as the main identifier. To do this, select 2.00 ACN for the Export version number setting on the Parameters tab.

TSAC-1238 Import, export, interoperability (concrete) HMS export: There is a new setting Generate drain/weep holes on the Options tab for exporting drain holes and weep holes. You can also specify the offset.
TSAC-1747 Import, export, interoperability (concrete) Export Unitechnik (79): Braced girders created as steel parts are now exported correctly.
TSAC-1799 Import, export, interoperability (concrete) Export Unitechnik (79): Line attributes override functionality is now working correctly for turned double wall shells.
TSAC-1818 Import, export, interoperability (concrete)
Export Unitechnik (79): Electric tubes are now exported correctly when you specify to cut outer assemblies.
TSAC-1883 Import, export, interoperability (concrete) Export EliPlan file (68): You can now export selected cutouts and embeds as lines using the new setting Plot cutout/embed as lines on the Plotter data tab. You can specify the cutouts and embeds by name, class or material.
