Create a rebar assembly

You can create basic, one-level rebar assemblies or nested, hierarchical rebar assemblies. Start by creating basic rebar assemblies. If needed, you can later add more objects or sub-assemblies, or form hierarchies by adding these basic rebar assemblies as sub-assemblies to higher-level rebar assemblies.

A reinforcement object can only have one relation, either to a concrete part or to a rebar assembly. When you add a reinforcement object to a rebar assembly, it will be detached from the part. If a reinforcement object already belongs to a rebar assembly, it cannot be attached to a part.

Note that individual rebar set bars or rebar set bar groups cannot be added to rebar assemblies, only entire rebar sets can be added.

Create a basic rebar assembly

You can create a basic rebar assembly with various reinforcement objects on the same assembly hierarchy level.

The reinforcement object with the highest weight will become the main object of the rebar assembly.

Create the reinforcement objects that you want to include in the rebar assembly.
On the Rebar tab, click Assembly > Create rebar assembly.
Select the objects that you want to include in the rebar assembly.

You can select reinforcing bars, bar groups, rebar sets, reinforcement meshes, and strands.
Click the middle mouse button to finish selecting objects and to create the rebar assembly.

Tip:

Alternatively, you can first select the objects, then start the command, and finally click the middle mouse button. This may help in controlling that you have a correct set of objects selected for the rebar assembly.

Note that if you select components and want to include the component objects in the rebar assembly, the components need to be exploded first. Tekla Structures warns you about this and explodes the components when you click Yes in the warning dialog box.

Note that if you select parts and assemblies, they are added as sub-assemblies, and the rebar assembly becomes a nested assembly.

To modify the rebar assembly structure, for example, by adding or removing objects and hierarchy levels, see Modify a rebar assembly and Remove objects from a rebar assembly.

Rebar assembly properties

Use the Rebar assembly property pane to view and modify the properties of rebar assemblies. The file name extension of a rebar assembly property file is .ras.


Property	Description
Assembly numbering	Numbering prefix and start number (= numbering series) of the rebar assembly.
Name	User-definable name of the rebar assembly. By default, the name of the rebar assembly main object is shown in brackets [ ].
Rebar assembly type	Select the type for the rebar assembly. The options are (empty), Cage, Mesh, Bent mesh, Braced girder, Embed, and Roll mat.
IFC entity	For IFC export, select the IFC entity type and subtype of the rebar assembly. The available subtypes depend on the selected IFC entity. You can select the IFC4 subtype among the predefined options, or you can select USERDEFINED and then enter any text in User-defined type (IFC4).
Subtype (IFC4)
User-defined type (IFC4)
UDAs	User-defined attributes provide additional information about the rebar assembly, for example, workflow information. User-defined attributes can consist of numbers, text, lists, or dates. You can use the values of user-defined attributes in reports and drawings. You can also change the name of the fields, and add new ones, by editing the objects.inp file.
