Rebar end anchor: The status bar instructions for applying rebar end anchors to rebar set ends have been improved.

Wall layout: Wall panel geometry is now created properly also when an opening is located at the exterior edges and corners.

Wall layout T connector: Previously, the gap between the parts of the first layer was created twice the size of the value defined in the Free space option in the Wall layout T connector dialog box. This has now been fixed.

Rebar coupler, Rebar end anchor: Previously, the components did not use the custom component input option value controlled by Use auto attribute file. This has now been fixed. Changing the input point option in the component property dialog box with Use manually entered values worked correctly.

Rebar coupler and Rebar end anchor components have been modified so that they now clear all rebar UDA values if the coupler or end anchor is not valid. 

Rebar coupler: When creating a rebar coupler, Tekla Structures now checks the splitter overlap and shows a warning if it is not zero (or less). Status bar instructions for creating the component have also been improved and a warning is now also shown if the input is not valid, for example, if you select a part. 

Wall layout: Geometry calculation has been changed to properly handle situations where the opening goes outside the original exterior perimeter.

Mesh bars: The length of the bars and their dimensions have been fixed. Previously, Mesh bars could create infinite bars.

Embedded anchors (8): Previously, creating certain geometries on the Thickening tab could cause a crash. This has now been fixed.

Cold rolled overlap (1): Previously, the component worked incorrectly for user-defined Z profile secondary parts. This has now been fixed.

Purlin connections (11): Previously, bolts were sometimes created on the opposite side of the secondary beam. This has now been fixed.

Base plate (1042): Previously, the cast plate did not follow the offset of the base plate. This has now been fixed.

Welded beam to beam (123): Previously, the secondary part bottom flange was not cut correctly. This has now been fixed.

Bolted moment connection (134): Previously, when the flange plates were wider than the column, they were created incorrectly. This has now been fixed.

Web stiffeners (1060): Previously, when creating only an above line weld or a below line weld, both welds were always created. This has now been fixed.

Bolted gusset (11): Previously, when using a twin profile as the secondary part, only one member of the twin profile was welded to the gusset. This has now been fixed and both members of the twin profile are welded.

Bolted moment connection (134): Previously, when the secondary part was sloped and the shear tab was set to be created parallel with the main part, the shear tab was not created. This has now been fixed.

Joining plates (14): Previously, different selection order of parts caused the component to work differently. This has now been fixed.

Two sided end plate (143): Previously, the bolt gage was incorrectly applied in the component in some situations. This has now been fixed.

Simple clip angle (31): Previously, the bolt extra length was not correct if the bolts were used with a U profile as the secondary part. This has now been fixed.

Stiffened end plate (27), Partial stiff end plate (65): Previously, holes in the end plate were created with incorrect rotation in some cases. This has now been fixed.

Previously, Organizer synchronization could fail in case an assembly had lost its main part. This has now been fixed.

Previously, Organizer data was corrupted in a Tekla Model Sharing model if the assembly of a part was missing. This has now been fixed.

Previously, importing attributes by object GUID did not import attributes for bolts, welds and rebars. This has now been fixed.

IFC2x3 export: The export of rebars failed because of too long spacing value. This has now been fixed, and the Open API Rebar group spacing maximum value has been increased from 99 to 1000.

Export drawings to DWG/DXF: The drawing export now supports loading settings with a macro.

IFC2x3 export: The z level failed in the export in Tekla Structures 2021 if the base point local z coordinate was used. This has now been fixed.

Trimble Connector: When you upload your model to the linked Trimble Connect project as a .tekla model, the export can now read profile information (profitab.inp file) from XS_PROJECT and XS_FIRM folders.

The profile conversion files used in import and export between Tekla Structures and Tekla Structural Designer have been fixed. Each conversion file line now contains one profile entry with the neutral file profile name, the # symbol and the profile code, and then the equal sign (=) followed by the Tekla Structures profile name.
For example: STB 229x305x70#00610=TEE229*305*70
Note that you may need help from your local Tekla support with the conversion files.

Also, several errors in the conversion for US metric profile names have now been fixed.

IFC object conversion: Now the conversion supports the copying of the object type (IfcRelDefinesByType) property set property to UDA.

IFC4 export: Sometimes exporting objects with a certain chamfer caused a Tekla Structures application error. This has now been fixed.

IFC object conversion: The IFC object conversion now converts solid model presentation objects.

IFC2x3 export: The export did not export the object location correctly with edge chamfer offsets. This has now been fixed.

Some HP profiles, hollow sections and pipes were not included in the standard profile conversion, resulting in "Missing profiles detected" messages when imported from Tekla Structural Designer for US Imperial and US Metric models.

IFC object conversion: The failing column handle offset in the B-rep to extrusion conversion has been fixed.

IFC object conversion: The IFC B-rep to extrusion object conversion sometimes created beams to bottom of the object and location failed. This has now been fixed.

IFC4 export: The IFC4 export file name with a dot removed the rest of the file name. This has now been fixed.

Template Editor: Editing the font color of multiple text objects worked only the first time the font color was changed. This has now been fixed.

Missing definitions in pull-out height and width parameters in templates could cause Tekla Structures to crash. This has now been fixed.

When an xls report was created and opened in Microsoft Excel, Microsoft Excel could freeze if the report contained references to image files with long paths. The reason was that the valuefield content was longer that the length specified for it, and therefore the path to the image file was cut. This has now been fixed so that if the valuefield content starts with the text '<IMG' and ends with the character '>', the path is not cut.
If the above case is discovered during template output, a warning message is written to the log indicating the maximum length and the path to the template file.

Reference object hidden lines were displayed in drawings even though they were disabled when the line type and color of the lines matched the properties of the visible lines. This has now been fixed.

Grid dimensions did not work correctly if a drawing filter was applied. This has now been fixed.

The positioning of the level mark base points in drawing update has been improved. Holding down Shift and dragging the level mark away from the part keeps the valid associativity data (just like when you use the Move linear command).

Reflected views now work correctly in drawings.

Snapping to center lines now works identically in drawing and modeling modes: Center lines are snapped to when the Snap to geometry lines/points switch is enabled. Center lines are no longer snapped to in drawings when the Snap to reference lines/points switch is enabled.

Part center line associations that were saved incorrectly in some cases are now saved correctly.

Document manager: Exceptions occurred when you rapidly toggled data cell values by editing those directly in columns that you sorted. This has now been fixed.

Sometimes, the part to grid dimensioning in GA drawings did not work correctly. This has now been fixed.

Level marks are now placed correctly when a part has been modified. A zero level mark no longer gets a change cloud if only the sign (+ or -) changes.

Moving or resizing a drawing view frame no longer causes an application error.

Changing the view depth in drawings no longer causes a Tekla Structures application error.

In some cases, resizing drawing view frames could crash Tekla Structures. This has now been fixed.

Previously, you sometimes could not reserve the next write out directly after joining a model, but had to read in a packet first. This has now been fixed.

In Rebar shape manager, two new built-in geometrical properties are now available for circular arc legs:

• Arc width (AW)
• Arc height (AH)

In Rebar shape manager, the unknown rebar shapes are now read from the first RebarShapeRules.xml file, following the same reading order as the other, recognized shapes. Previously, the unknown rebar shapes were read from the last RebarShapeRules.xml file.
Note that if you modify the rebar shapes and then save the rebar shape definitions to the model folder, you need to reopen the model to apply the changes.

In Rebar shape manager, the value of the REVERSED property is now calculated correctly for curved bars.

In Rebar shape manager, the value of the Arc length (AL) property is now calculated more accurately for curved bars, regardless of the modeling direction.

In Rebar shape manager, the curved bar arc length and angle were not correctly reported when the bar had hooks and the advanced option XS_REBAR_RECOGNITION_HOOKS_CONSIDERATION was set to FALSE. This has now been fixed.
 

Rebar groups have the following three issues fixed:

• Rebar group bars in a tapered rebar group with non-planar bar geometry were in some cases incorrectly offset from input points. This has now been fixed not to occur when creating new rebar groups. To get existing rebar group offsets fixed, you need to modify them.
• Tapered rebar groups which have exact spacings as the creation method and spacings defined so that there are too many bars compared to the group length were incorrectly handled in mirroring. This has now been fixed.
• The mirroring of tapered rebar groups containing non-parallel straight bars has now been fixed.

Previously, rebar set modifiers sometimes became visible when you modified the part the rebar set bars were attached to. This has now been fixed.

Rebar sets: Sometimes, when using rather big concrete covers, some bars were incorrectly shortened around holes. This has now been fixed.

Multi-user: Previously, modifying and saving drawings in multi-user models could sometimes detach rebars from their parent parts and flag their numbering as out-of-date. This has now been fixed.

Multi-user: In some cases, numbering old standard part models could cause Tekla Structures to crash. This has now been fixed.

Previously, autosave files were deleted without a new save being successful. This has now been fixed.

There is a new possibility to use separators in the .dat files for the fVF reference function.

• The fVF reference function can now use a preferred column separator of choice. Previously, it was possible to use only spaces as separators.
• You can use only a single character as a separator. For example, you cannot use a more complex separator such as "/+/", because only the first character would be considered as a column separator.
• The .dat file lines do not need to end with a space or separator anymore to retrieve the last element of the column.
• Columns can now include blank values if the separator is different than the default space separator. For example: =fVF(dat,2,2,"/")

With a data row of 2 / / NG / / 2.5 / / 50 60 50 25/ returns nothing (the empty string when mapped to text).

If you have the same model open in more than one Tekla Structures session, or if the model was not properly closed, Tekla Structures displays an error message about this situation. This message has now been improved.

If XS_ENABLE_POUR_MANAGEMENT is switched to FALSE in a model with cast-in-place concrete parts that form pours, you can now use the Diagnose & repair model commands to remove the obsolete pours from the model. Previously it was not possible to remove them, even by deleting the parts that formed the pours.

Previously, the applied or saved prefix for the steel item part numbering series was not used, but instead the prefix defaulted to the value P. This has now been fixed and the applied and saved values work correctly.

Sometimes perpendicular snapping happened to an unrelated, distant point. This has now been fixed.

Previously, when the Cut object with line command was used, no ortho symbols were shown irrespective of the cursor position. This now been fixed.

Previously, the workplane changed to model origin if you typed the values, for example, when you extended a beam. This has now been fixed.

In some cases, solids could be broken in cut bent plates, for example. This has now been fixed.

In the US environment, shape names that only consisted of numerical characters were unintentionally converted to imperial units. This affected filtering in the Object Group dialog box and labels in the 3D views. This has now been fixed.

When the Fast representation was used for parts, some pour object faces were not shown in pour views. This has now been fixed.

Sometimes Tekla Structures could crash at startup. This has now been fixed.

Previously, Tekla Structures crashed when the bolt visibility was set to Exact in 3d views. This has now been fixed.

Previously, the Applications & components catalog could be empty when the Windows regional setting Beta: Use Unicode UTF-8 for worldwide language support was selected. This has now been fixed. Note that it is not recommended to use this setting with Tekla Structures.

If you cancelled the save-numbering-save operation, Tekla Structures might sometimes crash. This has now been fixed.

Previously, in some rare cases, there was an error in the property pane about object reference not set to an instance of an object. This has now been fixed.

Export ELiPLAN file (68): The data conversion file now supports the wildcard "*" in regular expressions in the first column for finding strings from Tekla Structures objects.

Export Unitechnik (79): Previously, the UT_REBAR_TYPE UDA was not read for rebar sets. This has now been fixed.

BVBS Export: All bending and arc angles are now rounded to the nearest 0.5 degree. For example, 89.8 degrees will be rounded to 90 degrees.

Export ELiPLAN file (68): You can now specify the material code using the new setting, Material code, on the Data content tab. The options are Name, Assembly prefix, Material, Profile, UDA, Text[TEMPLATE], and Template.

BVBS export: When you select One file per each cast unit and use Assembly template property, the export will now warn if the export results in duplicate file names. The export will still continue.

BVBS Export: The file naming template by [Assembly template] now works with the PROJECT.NUMBER property.

Export ELiPLAN file (68): Exported files are now written with UTF-8 encoding.
