In Tekla Structures 2018, pour unit is a new object type similar to assemblies and cast units. A pour unit combines together a pour object and other objects that need to be in place before cast-in-place concrete can be poured. Pour units are present in the model when XS_​ENABLE_​POUR_​MANAGEMENT is set to TRUE.

• Pour hierarchy has now been changed so that the pour object and the other objects are directly under the pour unit, and the pour object and the other objects are on the same hierarchy level with each other.

  Previously, the other objects in the pour unit were below the pour object level in the hierarchy.

• When theSelect assemblies selection switch is active and you select a pour object in a pour view, the new object type, pour unit, is selected.
• You can now inquire and modify the pour unit properties using theSelect assemblies switch, or the pour object properties using theSelect objects in assemblies switch.
• When you select a pour unit and right-click, the same commands are now available for the pour unit as for assemblies and cast units, for example Hide , Fit Work Area , Create View > 3D View (neighbor objects are not shown), and Zoom > Zoom Selected.

Pour unit properties and pour object properties are now shown in the property pane.

Also the pour break properties are now available in the property pane. For example, you can define the pour break type or add comments.

In filtering and object groups, Pour unit is now available as a category, and as an object type value when the Object category is selected.

In Template Editor, POUR_UNIT is available as a content type for rows. This means that you can now create reports for pour units.

In templates, if you have rows that list object properties such as reinforcement properties under pour objects, these rows will be empty. Update your existing templates to follow the new pour unit hierarchy.

For more information about filtering, see Filter objects and Examples of filters.

You can now use pour units in Organizer categories in the same way as assemblies and cast units when XS_​ENABLE_​POUR_​MANAGEMENT is set to TRUE. When you select pour units in the model or in the categories, Object Browser shows the pour objects and any other objects added to the pour unit under the pour unit in the hierarchy.

Synchronizing Organizer updates all properties of the changed pour unit objects in the Organizer database. Location properties are now added to pour units in synchronization. You can use location information when you create reports and inquiries.

You can now add pour units to tasks in Task Manager.

Tekla Structures 2018 introduces new template attributes that you can use when you report pour unit information.

• VOLUME_ONLY_POUR_OBJECT
• WEIGHT_ONLY_POUR_OBJECT
• WEIGHT_ONLY_REBARS

• Sharing pour unit information has been improved. When the new advanced option XS_​CALCULATE_​POUR_​UNITS_​ON_​SHARING is set to TRUE , Tekla Structures now automatically calculates the pour units when users start sharing, read in, or write out. Previously (and with XS_CALCULATE_POUR_UNITS_ON_SHARING set to FALSE ), each user had to run the Calculate pour units command in their local version of the shared model when they needed up-to-date pour unit information.
• Pour units are now shown in the sharing changes list at the bottom pane of Tekla Structures. The list shows the changes after you have read in the model changes from the sharing service.

• Now Tekla Structures only checks for the new and modified rebar sets when it calculates the pour units. This improves the performance. Previously, when you run the Calculate pour units command, all rebar sets were checked.
