Number parts by design group

You can number parts by design groups so that you can differentiate the parts from each other in drawings and reports. The design group numbers can be used in engineering documents or as preliminary numbers.

Design group numbers consist of a prefix, a separator, and a number or a letter.

Use the Design group numbering application to assign prefixes and numbers or letters to parts on the basis of design groups. The Design group numbering application groups parts that match a selection filter into a design group, numbers them, and optionally compares the part lengths. The application also compares the user-defined attributes of parts that are set to affect numbering.

Note:

The Design group numbering application only numbers parts that have a profile extruded to create the length of the part, such as beams, columns, panels, and footings. Contour plates, slabs, or items are not numbered.

Before you start:

  • Create the needed selection filters that define the design groups.
  • If you want to use certain letters in design group numbering, list the allowed letters using the advanced option XS_​VALID_​CHARS_​FOR_​ASSEMBLY_​POSITION_​NUMBERS. By default, letters A–Z are allowed.
  • In multi-user or Tekla Model Sharing models, make sure that only one of the users runs the Design group numbering application.

To number parts by their design group:

  1. In the model, Click the Applications & components button in the side pane to open the Applications & components catalog.
  2. Click the arrow next to Applications to open the applications list.
  3. Double-click Design group numbering to start the application.
  4. In the Design group numbering dialog box:
    1. Click Add group to create design group numbering settings for parts matching a selection filter.
      • Select the filter in the Group filter column.

        The selection filters are read from specific folders in the standard folder search order.

      • Enter the design group prefix and start number or start letter you want to use for the parts in this group.
      • In the Compare length column, define whether the part lengths are compared or not.
    2. Repeat step 4a for all part groups that you want to number by design group.
    3. If needed, change the order of the groups by using the Move up and Move down buttons.

      If a part belongs to several groups, the last group filter in the list overrides the previous ones.

    4. If you want to compare part lengths, define the length tolerance.

      For example, if you enter 0, parts must be exactly the same length to receive the same design group number (or letter). If you enter 2, part lengths can differ 2 mm from each other.

      The default tolerance is 0.05 mm.

    5. Enter a number separator that is used to separate the design group prefix and number or letter in drawing marks and in reports. For example, enter - .

      We recommend that you do not change the separator during the project.

    6. To reuse old, unneeded numbers or letters, select the Reuse old numbers check box.
    7. In Number using letters, select whether to use letters or not.
    8. In Renumber all, select whether to renumber all parts or not.
    9. To number the parts by design group, click Perform numbering.

      A design group number is saved as the user-defined attribute DESIGN_GROUP_MARK of each part.

      By default, the user-defined attribute DESIGN_GROUP_MARK is available in the objects.inp file in the Engineering configuration in the default and US environments.

    10. To create a report to show the numbering results, select whether to create a report of all or the selected parts, and then click Create report.

      Tekla Structures shows the report in the List dialog box and also saves the report. The report is saved as dgnReport.txt in the folder defined by the advanced option XS_​REPORT_​OUTPUT_​DIRECTORY. In the Default environment, the report is saved in the \Reports folder under the current model folder.

      When you select a row in the List dialog box, Tekla Structures highlights and selects the corresponding part in the model.

      If the numbering of a part is not up to date, meaning that the part has been modified after numbering, a question mark (?) is added after the design group number.

  5. To show the design group numbers in drawing marks or in reports, use the user-defined attribute DESIGN_GROUP_MARK.
