• Snapping has been improved in Tekla Structures 2019 to make it work better with the Ortho tool.

  Previously, when Ortho was on, Tekla Structures remembered the last plane and used the last picked point as a reference point, and continued to snap to the plane where you had last picked a point. This resulted in unwanted snapping results, for example, parts were created to a different plane than expected.

  Now, when you interrupt a command, the reference point information is cleared. This means that there is no reference point information, meaning the last picked point, that the orthogonal snapping could use. This results in more accurate snapping.

  When you need to use the reference points, set the reference point manually by pressing the Ctrl key and picking a point when you run a command.

• Previously, when the Ortho tool was active, the snapping distances were incorrectly rounded. This has now been fixed.
• When using orthogonal snapping, the snap points are now shown with perpendicular snap symbols.

There is now a new option in the Bolt properties that you can use to specify which plies of the connection do not get holes.

To do this:

1. Go to the Holes section in the Bolt property pane.
2. Next to Parts with slotted holes , select the desired Special hole check boxes.
3. In the Special hole type list, select No hole.
4. Click Modify.

The No hole option is also available for bolts in the system and custom components.

If you are following the ISO standard (2553) for welds and have the advanced option XS_AISC_WELD_MARK set to FALSE , you can now specify whether the fillet weld size determines the leg length or the throat thickness.

Set the new advanced option XS_​​ISO_​LEG_​​LENGTH_​​AS_​​WELDSIZE to:

• TRUE to use the weld size as the leg length (z) of the fillet welds.
• FALSE to use the weld size as the throat thickness (a) of the fillet welds.

This advanced option is model specific and the setting is saved in the options database. This advanced option also applies to the fillet welds in compound welds.

Note that setting a weld prefix that affects the weld size overrides the value set in XS_ISO_LEG_LENGTH_AS_WELDSIZE.

The Pour > Add to pour unit and Pour > Remove from pour unit commands are now visible on the context menu for more combinations of selected objects when right-clicking.

The following commands are also available in Quick Launch , and you can assign keyboard shortcuts to them:

• Add to pour unit
• Add selected objects to pour unit
• Remove from pour unit
• Remove selected objects from pour unit

Using these commands makes it easier to add allowed objects to pour units , or to remove them, even when you have a set of objects selected that also includes objects that cannot be added to a pour unit.

If you need to reset pour unit contents and relations defined using the Calculate pour units command and/or the Add to pour unit command, you can use the following commands in Quick Launch :

• Reset all pour unit relations
• Reset all manually assigned pour unit relations
• Reset all pour unit relations except manual assignments

It is now easier to add and move items in the model in the same way as custom parts, and to adjust item location and rotation using the axis and rotation handles.

If some previously imported shapes cause missing faces or edges in items or drawings, you can use the new Shape cleaner application for cleaning the shape geometries in Tekla Structures models. Cleaning means that Tekla Structures investigates and corrects the shape geometry and tries to create solid objects. This is useful with shapes that have been imported to Tekla Structures models prior to version 2018i and are migrated to version 2018i or newer. Shape cleaner provides an option to create backups of the shape geometry files and to revert to the original files if you are not happy with the cleaning result.

Shape cleaner is available in the Applications & components catalog.

In the Numbering Setup dialog box, Phase has been changed to Assembly phase. Now the Assembly phase setting only affects the numbering of assemblies, not the parts. This means that only the assembly phase of assemblies is compared in numbering, not the part phase nor the assembly phase of parts.
