Category : Numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

Use to base cast unit numbers on drawing numbers. Use the following switches to define the contents of cast unit marks. Use as many switches as you need, and enclose each one in percent symbols (%).

The available switches are:




Multidrawing name.


Position of the cast unit drawing inside the multidrawing.


Cast unit prefix in the model.


Cast unit position number in the model.

Template fields

Enter TPL: followed by the name of any relevant template field. Enclose each name in percent symbols (%). For example, %TPL:PROJECT.NUMBER%

NOTE: No template fields starting with DRAWING work for this advanced option, for example, DRAWING.TITLE1. If you use them in the value, Tekla Structures will replace the whole value string with the default value.

User-defined attributes that are defined in the objects.inp file

Enter UDA: followed by the name of any relevant user-defined attribute, exactly as it appears in the objects.inp file. For example, %UDA:MY_INFO_1%

This advanced option is model specific and the setting is saved in the options databasedatabase file that contains the settings of model-specific general settings and advanced options

There are two options databases, the model options database (options_model.db) and the drawing options database (options_drawings.db).



To put the cast unit multinumbers in the format multidrawingdrawing that gathers together several drawings on one sheet

The individual drawings in a multidrawing may be of any drawing type.

name + part prefix + position on multidrawing, set the advanced option as follows:


This will create the cast unit mark 10B1, where:

  • 10 is the drawing number

  • B is the cast unit prefix

  • 1 designates that it is the first cast unit on the sheet.
