| Introduction This section discusses the principles you need to consider when planning numbering. Tekla Structures uses numbers to identify parts, cast units, and assemblies when producing drawings and reports, and exporting models. You must have Tekla Structures number the model parts before you can create single-part, assembly, cast unit, and multdrawings, or some export files from a model. Tekla Structures uses part numbers in many tasks, for example: • Connecting a drawing with the right part, cast unit, or assembly. • Reporting the properties of identical parts, cast units, and assemblies. • Identifying part information for export another program. |

| Defining numbers to be used for parts | |||
| Numbering series You use a numbering series to divide steel part, cast unit, and assembly numbers into groups. For example, you can allocate separate numbering series to different phases or part types. You can name the numbering series to which a part, cast unit, or assembly belongs, using the part properties dialog box. The numbering series name consists of a prefix and a starting number. Example For example, if you define a numbering series with the prefix P and starting number 1001, Tekla Structures numbers that series P1001, P1002, P1003, … |
|||
| By default, the steel part mark prefix is P, the concrete part prefix is Concrete, and the starting number is 1. You do not have to specify 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. |

By default, a part retains its number, as long as only one part has that particular number, regardless of the settings in the Numbering setup dialog box. |
||||||||||||||||||||||||||||||
| Cast units Tekla Structures numbers concrete cast units and steel assemblies using the same principles as and assemblies it follows when numbering parts. The default starting number is 1. The prefix varies based on the part type. |

Assembly and cast unit numbering may affect part numbering, if the variable XS_USE_ASSEMBLY_NUMBER_FOR is set. | ||||||||||||||||||||||||||||||
| Part numbering does not affect cast unit and assembly numbering. For more information on cast units and assemblies, Overlapping When planning numbering, ensure that you reserve enough numbers for each series. If one series series overflows into another, Tekla Structures might allocate the same number to different parts. Tekla Structures warns you about series overlaps. View the numbering history log to check which numbers overlap. See Log files in the online help. Identical parts Tekla Structures treats parts as identical, and so gives them the same number, if the following basic part properties are the same: |

| Part property | Condition | ||||||||||||||||||||||||||||||||||||||||||
| Material Finish | |||||||||||||||||||||||||||||||||||||||||||
| Class and phase do not affect numbering. Tekla Structures gives the same number to identical parts that belong to different classes or phases. | |||||||||||||||||||||||||||||||||||||||||||
| You can set the degree of tolerance for part geometry in the Numbering setup dialog box. If the geometry of parts differs within this degree of tolerance, Tekla Structures treats the parts as identical for numbering purposes. Additional Tekla Structures treats parts as different, and so numbers them differently, if the following properties properties differ:

| Cast units and Tekla Structures numbers cast units and assemblies in the same way as it does parts. The assemblies orientation of assemblies also affects numbering if you select the Beam orientation and Column orientation checkboxes in the Numbering setup dialog box. |
