Create customized bolt symbols

You can create your own bolt symbols in Symbol Editortool in Tekla Structures that is used for creating and modifying symbols to be used in drawings, reports, and templates

The symbols are saved in symbol files.

and use them in drawings. You only need to create bolt symbols if you need different bolt symbols than the ones that you can find in Tekla Structures.

  1. Save the symbol filefile that contains symbols

    The symbol file in use can be changed in the symbol files dialog box.

    ud_bolts.sym in the symbol folder (usually the folder ..\Tekla Structures\<version>\environments\common\symbols\ ).
  2. Open Microsoft Notepad, or any text editor.
  3. Create a text file consisting of lines in three columns:
    • The first column contains the bolt assemblyset of bolt elements that consists of a bolt, a stud, or a screw, and possibly the related washers and nuts


    • The second contains the bolt diameter.

    • The third column contains the name of the symbol file and the symbol number, separated with the @ character.

      Example of file contents:

      7990 24 ud_bolts@1

      7990 25 ud_bolts@2

      Tekla Structures uses the user-defined symbol for bolts in drawings that have the standard and diameter you define in this text file.

  4. Save the file with the name bolt_symbol_table.txt.
  5. Set the name of the file as a value for the advanced option XS_USER_DEFINED_BOLT_SYMBOL_TABLE in File menu > Settings > Advanced options > Marking: Bolts as follows:


    You can also enter a full path to the bolt definition file. Without the path Tekla Structures searches for the file in the model, firm, project, and system directories.

  6. To use your own bolt symbol, click Bolt > Content > Solid/Symbol > User-defined symbol in the drawing viewview that includes selected model objects or an area in the model, that is represented in a drawing

    A drawing view is a container for model and drawing objects.

    A drawing can include several drawing views, which usually are two-dimensional views, plane views, to the model.

    Examples of drawing views in Tekla Structures include main views, section views, single-part views, and 3D views.
