New property pane in drawings

In Tekla Structures 2023, you will experience a more streamlined way of working in drawing mode as most drawing objects now have a property pane instead of dialog boxes. The property pane is a side pane window, where drawing object properties are accessible in one place.

Show only frequently used properties in the property pane

You can control separately for each object type which properties are shown in the property pane, and create your favorite sets of properties for every object type. This way you can make the property pane less cluttered by hiding the properties that are not needed frequently. Customize the property pane layout using the Property pane editor, and mark each property as frequently or infrequently used.

Printing improvements

• If the list of drawings to be printed contains drawings that require numbering or updating, this is now indicated in a separate dialog box that is displayed before you can start printing. You can select to Print only up-to-date drawings (recommended) (default), Number and update before printing drawings, or Print drawings without updating.
• When printing to PDF, if a correct font containing the needed multibyte characters is selected for Unicode characters, for example, in marks, the font is now shown correctly even if you do not embed the fonts.
• The new advanced option, XS_DEFAULT_UNICODE_FONT_DRAWING_PRINTING, defines the default font that is used when the selected font for drawings and printing does not contain all of the characters used in the text. When a default font is defined, the characters are shown correctly even without embedding fonts. By default, the font is set to Arial Unicode MS. There are also other improvements related to fonts.
• There are also many more important improvement. For example, you can change the tray from the printer properties and the tray selection is saved, and use a bypass tray. Old snapshots also work, and the positioning in snapshots, previews, and printing is working correctly.

Slotted holes with offsets, tapped holes, and other bolt hole improvements

• You can now create slotted holes where the bolt is not in the middle of the hole. The allowances and offsets of slotted holes can be defined separately for both hole or bolt group directions.

• A new Special hole type option, Tapped, and the Core hole size box have been added to the Bolt properties. In Core hole size, you can define the predrilling hole size for a tapped hole.

• When several parts are connected together with a bolt group or single bolt, it is now possible to create different holes in each of the parts by clearing the new Use the same settings for all special holes check box in the Bolt properties. The holes in one part can be slotted, and the holes in the other parts can be either special or standard holes.

• There are new advanced options for tapped and oversized bolt holes.

• There are new template attributes for bolt holes.

Reinforcement improvements

• Tekla Structures 2023 comes with changes in rebar shape recognition.

• The tolerances that are used in rebar shape recognition can now be set using model-specific advanced options, or for certain grade and bar size combinations in the rebar catalog, or for individual reinforcement objects in their Shape recognition user-defined attributes:

  • XS_REBAR_RECOGNITION_CURVE_TOLERANCE sets the default value for Curve tolerance

  • XS_REBAR_RECOGNITION_EXTRA_POINT_SHORTENING sets the default value for Extra point shortening

  • XS_REBAR_RECOGNITION_MAXCURVE sets the default value for Max curve radius requiring bending

• A new user-defined attribute, Recognize as straight bar, is available for reinforcement objects. You can use it to have Tekla Structures recognize individual reinforcement objects as straight bars even though they are bent in the model.

Modeling improvements

• Updated status bar messages give clearer descriptions and instructions how to proceed when a command is started.

• The numbering process of identical, copied parts is considerably faster in Tekla Structures 2023 than earlier.

• It is now easier to control what is included in clash checking by using the Between parts, Between reference models, and Objects in reference models settings in the Clash check manager dialog box. You can easily change the clash check content according your needs by selecting the appropriate settings.

  Previously, the settings were also controlled by the values defined for the related advanced options. These advanced options have now been removed.

• Previously selected properties are now used when copying properties in the Property pane.

• The Dashed line for hidden line option does not require restart anymore.

• If you have added base points or saved work planes to the Work plane handler toolbar and close the model, the last used work plane or base point is now used when the model is reopened.

• CustomComponentDialogFiles are selected by default when using the Saving as Model Template command.

• In Support tool, you can now prevent the tool from preselecting all files for sending in your support request with the new advanced option XS_SUPPORT_TOOL_EXCLUDE_ALL_FILES.

Base point improvements

Now you can use the same base point settings in several models and lock base points to avoid unwanted changes. In addition, you can no longer save a base point without giving it a name.

Dimensioning improvements

• Now the neighbor parts have their own dimensioning type, Neighbor part dimensions.
• The dimensioning method Filter has a new Only objects on the selected sides check box in rule creation allowing you to only dimension objects that are on a certain side of the main part, for example, Front side.
• The Filter method performance has been improved in large models. The Filter method no longer dimension objects that are not visible in the drawing view.
• Automatic dimensions and dimension tags are now updated correctly in cast unit drawings. Earlier, when you modified automatically added dimensions manually, or modified the model and reopened the drawing, extra dimension points or tags were sometimes added in the drawing, or dimension tags were updated otherwise incorrectly.
• The overall, filter, and grid dimensions are now working when the drawing only contains a rebar assembly.
• The performance of the Rebar group dimensioning tool has been improved.

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. Now marks saved in one language can also be loaded in any other user interface language.

Key plans handled correctly in multilingual projects

Now key plans are handled and shown correctly in drawings also when the original model language and the current Tekla Structures language differ.

Improved pull-out pictures

• You can now create as simple as possible rebar pull-out pictures out of the most complex rebars so that the rebars can be visualized in an easily understandable way in drawings and reports.
• Rebar pull-out pictures of bars that have multiple arc legs, or arc and straight legs, now include a dimension showing the total length of the bar.
• The bending angle tolerance has now been increased to 0.5 degrees, to match the Rebar shape manager default value.

Colors in property pane indicated with names

The drawing property pane drop-down menus, where you can select colors for various drawing objects, now contain the names of the colors.

Improvements in Layout editor

• With the new Layout editor context menu command Replace table you can replace tables in your layout.
• The user interface and the usability of the Save layout dialog box in Layout editor have been improved.

New macros for relabeling section views and detail views

When section or detail views have been removed from a drawing, these macros can be used for relabeling all the section or detail views to have continuous numbering again.

Other drawing improvements

• In Drawing content manager manager, the column sorting is now cumulative.

• The advanced option XS_DRAW_BOLTS_PERPENDICULAR_TO_PART_IN_SINGLE_DRAWINGS now also affects how bolts are shown in single-part drawings included in multi-drawings, and in single-part views in assembly drawings.
• The most time consuming calculations related to drawing opening have been identified and improved, and text rendering is faster now when FOG rendering is used.
• The obsolete Drawing tools macro has been removed from the Applications & components catalog. The Create moment connection symbols macro is now available separately in the Applications & components catalog, and all other drawing tool commands are available on the drawing mode ribbon.

Template Editor improvements

Tekla Structures 2023 comes with many enhancements related to template editing, for example:

• Dialog box button keyboard shortcuts Alt+O for OK and Alt+C for Close now work.
• You can now define a visibility rule for shape and text objects.
• Ther are two new string functions, join and join2, for formulas and rules to combine a list of values to a single string that has list items separated with an optional separator.
• When you changed the display scaling factor, the side pane could become too narrow to use. Now when Template Editor starts, it checks the scaling factor and, if required, adjusts the side pane width, and restart automatically.
• The new command Save as version allows you to save a template as a previous version template (like 4.0 (Tekla Structures 2020) or 3.6 (Tekla Structures 2019i or older)).
• You can use the new PAGES attribute to show the total number of pages in the report with the GetValue("PAGES") function.

Building hierarchy - create and manage levels and spaces

• You can use Building hierarchy to define a location breakdown structure for one building in your model. Building hierarchy has a default hierarchy structure, project > site > building > level > space. You can add levels and spaces to the model by either importing them from a reference model, or creating them directly in your model.

  Set the USE_INTEGRATED_BUILDING_HIERARCHIES advanced option to TRUE to use Building hierarchy. You can find to the building hierarchy commands on the Manage tab on the ribbon:

Tekla Model Sharing improvements

• Previously, sharing of drawing versions in Tekla Model Sharing did not work as expected and drawing versions got lost when you wrote out. Now, the drawing versions are not deleted when you write out. Additionally, the deletion of unnecessary drawing files can be controlled by using advanced options.

  Controlling whether unnecessary drawing files are deleted now works the same way as with multi-user models. Use the advanced options XS_DELETE_UNNECESSARY_DG_FILES to define whether unnecessary drawing files are deleted and XS_​DELETE_​UNNECESSARY_​DG_​FILES_​SAFETY_​PERIOD to define the time frame after which unnecessary drawing files are deleted.

• Now, in Tekla Model Sharing, drawing files are restored if the .dg files have been accidentally deleted. Deleted drawings are copied to the ModelSharing\BackUpEnv folder and are checked against to the drawings on the Drawing list.

• On the Shared models dialog box, when you click the Remove from cloud button, the button has a new icon.

• Previously, reading in the sharing changes in Tekla Model Sharing was sometimes extremely slow if the model contained a large number of custom components that had been duplicated from plugin components with an identical name. A warning dialog box was shown, and you had to click the OK button multiple times on the dialog box to pass the warnings and being able to continue. Now, the components are no longer automatically updated when you read in. This results in faster performance.

• The user interface of the Management Console for Tekla Model Sharing has been extensively updated. The look and feel has been updated to be consistent with other Trimble cloud services.

IFC improvements

• IFC4 export: The IFC4 Export dialog box contains a new Cast-in-place export setting, which allows you to select more precisely what to include in the cast-in-place export. The options are Pour units or pour objects and CIP cast units or parts. This setting replaces the earlier Pours check box.

• IFC4 export: Now, if you do not select Spatial hierarchy from Organizer in the IFC4 export settings, Tekla Structures first tries to take the export hierarchy (IFC building name and IFC building storey name) from the part UDAs. If the export hierarchy is not defined in the part UDAs, the hierarchy is taken from the project UDAs.
• IFC4 export: Some IFC entities have new subtypes.
• IFC4 export: Now you can select which system to use when you export to IFC4 and the location is based on a base point. When you have defined a base point for Location by in the IFC4 export dialog box, you can use the new setting, Base point export, to ensure that the collaboration works with other parties in the project. The available options are IfcMapConversion and IfcSite coordinate system.
• IFC2x3 and IFC4 export: The XS_EXPORT_IFC_REBARSET_INDIVIDUAL_BARS now works as expected.
• IFC2x3 and IFC4 export: IfcStair is now available for parts and IfcDiscreteAccessory for assemblies as an IFC entity. Also selecting IfcRamp for parts, assemblies, pour objects, or pour units now works.
• IFC2x3 and IFC4 export: There are some new entity types: IfcBearing, IfcBridgePart, and IfcChimney.
• IFC2x3 and IFC4 export: The Property set definitions dialog box now supports better the creation of the boolean property type.
• IFC object conversion: The conversions now swaps the handle points (start and end points) for I profiles, and after the IFC object conversion, the start and end point order in the native Tekla Structures objects is similar to the order in the IFC objects.

Drawing DWG/DXF export improvements

• Now you can select whether to include in the drawing DWG/DXF export the drawing views that are located outside the drawing area. A new check box, Include views outside the drawing frame, has been added in the Export drawings as DWG/DXF dialog box for this purpose. If you do not select the check box, the export excludes the drawing views that are outside the drawing area.
• When the Include views outside the drawing frame check box is selected, the export preview is enlarged to show all included views.
• The version 2023 has also more improvements in DWG/DXF export, for example, visible template names in the DWG export block names, improved export preview, correctly exported circular bolt hole symbols, and support for imperial scale.

• In addition to the shape properties that are shown by default in the shape catalog, you can now add user-defined attributes to the selected shapes.

• When you move or copy shapes to another group, you now have the option to use a new dialog box to select the group for the shapes.

• The property list on the right side of the Shape catalog and Select shape dialog boxes now shows units next to the shape property values and user-defined attribute values. Units are shown for area, length, volume, and weight according to the Units and decimals settings in the Options dialog box.

• Using the Shape cleaner application, you can now adjust the visibility of edges in a shape by defining a threshold angle between neighboring faces. You can make edges either visible or invisible.

Support tool improvements

You can now prevent the support tool from preselecting all files for sending in your support request with the new advanced option XS_SUPPORT_TOOL_EXCLUDE_ALL_FILES. Previously, all files were selected by default, which could cause problems with large models. This advanced option must be set in the user.ini or teklastructures.ini file. Note that this advanced option does not work if you define it in the options.ini file.

New fabrication drawings - create single-part, assembly and cast unit drawings more efficiently

• The new Create fabrication drawing functionality allows you to create drawings by using saved settings predefined for different model objects, or by using existing drawings in your model as templates.

• After selecting model objects, enable or disable the Creation review and Smart create switches depending on whether you want to create drawings immediately, or open the Creation review dialog box for more controlled creation process.
• To create drawings fast based on the best matching drawing template in the current model, select objects in the model, enable the Smart create switch only. If a matching drawing is not found, drawings are created from the settings applied in the drawing properties dialog box.
• If you enable the Creation review switch, the Creation review dialog box is displayed, where you can control the objects that are displayed and get drawings, the settings that are used for creating the drawings, and the override settings.

New reinforcement object type - rebar assembly

• Tekla Structures 2022 introduces rebar assembly, a reinforcement object type that combines together any reinforcement object types. Rebar assemblies are useful when you model reinforcement cages or custom meshes that will be prefabricated, for example.

  The rebar assembly modeling commands can be found on the Rebar ribbon tab, under Assembly.

• You can now create drawings for rebar assemblies with the new Create fabrication drawing command, define view-specific rebar assembly representation settings on the Rebar assembly tab in drawing view properties, and add assembly position in reinforcement marks and associative notes.
