Create cast units

By default, each concrete part is considered a separate cast unit. For construction purposes, you may need to merge several concrete parts into one cast unit. For example, a single cast unit could consist of a column with corbels.

Define the cast unit type of a part

You must define the cast unit type of concrete parts. Tekla Structures checks the cast unit type of the main part each time you create or modify a cast unit. Precast and cast-in-place parts cannot be mixed within a cast unit.

Double-click a concrete part to open the part properties in the property pane.
Go to the Cast unit section.
In the Cast unit list, select one of the following:
- Cast in place
  
  Cast units that are constructed fully in their final location.
- Precast
  
  Cast units that are built at another location and transported to their final location for placement in the full structure.
Click Modify to save the changes.

Note:

It is important to use the correct cast unit type, because some functionalities, for example numbering, are based on the cast unit type.

Create a cast unit

You need to specify which parts form the cast unit. Cast units can include reinforcement, as well as concrete parts.

On the Concrete tab, click Cast unit > Create cast unit.
Select the objects you want to include in the cast unit.
Click the middle mouse button to create the cast unit.
