Use numbering series to divide steel parts, assemblies, and cast units into groups. For example, you can allocate a separate numbering series to each phase or part type. Using separate numbering series for different parts speeds up the numbering operation.
The name of a numbering series consists of a prefix and a start number. You do not always have to define a part prefix (for example, you may want to omit the part prefix for minor parts).
When you run numbering, Tekla Structures compares parts that belong to the same series with each other. All identical parts in the same numbering series are given the same part number.
Concrete parts are numbered according to the cast unit numbering settings. For example, if the cast unit prefix is C and the start number is 1, concrete parts will get the part prefix Concrete_C-1.
This applies also to concrete components whose part position prefix is Concrete and start number is 1.
For example, if you define a numbering series with the prefix P and start number 1001, Tekla Structures numbers that series P1001, P1002, P1003, ...
