performance has now been improved in situations where you open an old model in an environment where a substantial number of property definitions has been changed.

When you export data to Excel and select the Export without column headers option, the Count column header is not added to the export anymore.

The profile mapping now works in the following way:

• Arbitrary profile mapping by name does not need to match the dimensions.
• Arbitrary profile mapping by name can be set to require dimensions to match by setting the new advanced option XS_CONVERSION_ARBITRARY_PROFILE_MAPPING_BY_NAME_MUST_MATCH_DIMENSIONS to TRUE. The default is FALSE.
• Parametric profilepredefined profile whose cross section dimensions the user can change by using parametric variables
  
  conversion by profile name mapping does not need to match the dimensions.
• Parametric profile conversion tries to find a corresponding library profile and if any profile does not match the parameters, the default parametric profile will be used.

DWG drawing export: Previously, the Export drawings to DWG/DXF dialog box would not open if the advanced option XS_DRAWING_PLOT_FILE_DIRECTORY had no value. This has now been fixed.

The property pane can be used to show and modify the properties of model objects.

performance has been improved when visualizing bent rebars which have a large bending radius.

Previously, if you used a Rebar coupler or Rebar end anchor component with rebar sets and manually attached the rebar set bars to another part, the components remained attached to the original part. This has now been fixed. Now both the rebars set bars and the components are correctly attached to the other part.

Rebar shape managertool that is used for customizing the bending shapes of reinforcing bars

Rebar shape manager can be used for bending shapes only and not for any other reinforcing bar properties.

has been changed so that multiple sequential bendings which form an arc are combined into one or more bendings (90 degrees or less) with the arc radius. This makes it possible to define bending shapes containing a large radius bending no matter how many individual bendings appear in the original bar geometry.

This functionality is in use when you set the new XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR advanced option to TRUE. The advanced option can also be set in a suitable .ini file:
SET XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR=TRUE

When the advanced option is set to FALSE (which is the default value), the bendings appear as multiple bendings and the shape is recognized as before.

In the Object Groupmodel objects with settings that match the settings that the user has defined for a certain purpose

In Tekla Structures, an object group is used on the one hand to control the transparency and coloring of model objects in the views and on the other in project management. Object groups can also be used in filtering tools, for example in selection filter, to select all objects that match certain properties.

- View Filterfilter used for defining which objects are displayed in a model view or drawing view

View filter chooses objects according to object properties. The user can filter objects according to their profile or material, for example.

In multi-user models, bolts could get incorrect properties in some conflict situations and thus look corrupted. This has now been fixed.

Previously, if there was a conflict in a multi-user modelmodel that is used for collaboration and that is opened in multi-user mode

and you clicked Review in the conflict message dialog box, Tekla Structures showed an error message when you viewed the conflict log. Now the error message is not shown anymore in conflict situations.

Previously, when you loaded a property filefile that contains properties or settings in the property pane or a dialog box

Property files are saved in the current model folder. The user can copy property files to the project or firm folders for future use.

User-defined attributes can be stored as a property file.

Previously, profiles whose SUB_TYPE was defined without quotation marks in the .lis file could not be imported. This has now been fixed.

When using the Ortho tool, the snap symbol is now again shown as the snap to any position symbol.

Models created with Tekla Structures versions older than 2017 could get corrupted if they were saved while runtime IDs were disabled. Saving models will now fail if runtime IDs are disabled, which will prevent models from being corrupted for that reason.

Previously, clash check could fail to detect clashes involving rebar sets with hooks. This has now been fixed.
