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.
