Tekla Structures – Numbering

With family numbering you can group objects within the same numbering series into different “families”. When you use family numbering, the cast unit position numbers consist of familynumber and qualifier. For example:

•     Assemblies or cast units which have the same family number but different exact geometry or materials get unique qualifier numbers.

Assigning family numbers for series

On the Family numbering tab, you can assign family numbers for series.

For example, the following two beams both have the numbering series prefix B:

1.        Click Drawings & Reports > Numbering > Numbering Settings… to open theNumbering Setup dialog box.

2.        On the Family numbering tab, click Add series to open the Add series dialog box, which lists all the assembly and cast unit numbering series in the model.

assembly position, and the qualifier number will be 1 for all. If you do not select any checkboxes, only one family number per series is assigned.

5.         Click Apply or OK.

6.        Update the numbering in the model.

7.        Tekla Structures assigns the beams family numbering.

To assign a family number and/or family qualifier for parts:

1.        Select the objects whose family numbers you want to change.

2.        Click Drawings & Reports > Numbering > Change Number > Family Number….

3.         In the Assign Family Number dialog box, enter the desired values in the Family number and Family qualifier fields.

4.        Click Assign.

•      The x, y or z coordinates of the main part of the assembly.

•      The user-defined attribute of an assembly.

•      The user-defined attribute of the main part.

If your sorting is based on user-defined attributes, Tekla Structures displays a list box that includes all the available user-defined attributes.

When sorting by x, y or z coordinates, the sorting is based on the center of gravity of the reference axis.

If you add new parts, already numbered objects are not renumbered to suit the sorting order by, for example, the x coordinate. In this case you should renumber the parts.

Numbering examples

Part numbers             This example explains how different numbering settings result in different part numbers when

you modify a part.

1.    Create three identical beams with the numbering series prefix P and start number 1.

2.    Number the model. All the beams have the part position number P1.

3.    Modify one of the beams.

4.    Number the model. You should now have two beams P1 and one P2.

5.    Change beam P2 to be identical to the others.

6.    Number the model.

Tekla Structures assigns different part position numbers to this part, according to which numbering settings you used, as follows:

•      Compare to old: P1

•      Keep number if possible: P2

•      Take new number: P3

project phases           When you start modeling a project, the required numbering settings may be totally different

from what they are after the project has been issued for the first time and you start revising the model.

For example:

•     Phase 1 – Stick modeling

Doing only modeling before any drawings are released. At this stage you may even want to select Renumber all, or at least Re-use old numbers.

•     Phase 2 – Drawing issue

When the first set of drawings is issued, but modeling continues, you may want to minimize the effects to already issued drawings. You can do this for example by selectingKeep number if possible in the Modified list box.

•     Phase 3 – Revisions

At some point the project is more or less finalized, and any changes to the model should be handled in a different way than before. You may want to take a new number for all modified parts, not comparing them to any of the existing parts. To do this, select Take a new number in the Modified list box.

When you apply numbering, Tekla Structures assigns marks to parts and assemblies. Numbering is carried out according to the settings in the Numbering Setup dialog box.

Example

Interrupt numbering

Log file

Two main parts in different assemblies are identical, apart from a difference in the position of the plates welded to them. In this case, Tekla Structures assigns them different numbers.

You can safely interrupt numbering before it is complete by clicking Cancel in the dialog box Tekla Structures displays while it is running. If you interrupt numbering, parts and assemblies retain their original numbers.

Click Tools > Display Log File > Numbering history… for a report showing the numbering

bering

Control numbers are properties that identify the location of parts in a model. Use the Create control numbers (S9) macro to assign control numbers to parts. You can have TeklaStructures assign consecutive control numbers to all parts in the model, to selected parts, or only to parts in a specific numbering series. Each part gets a unique control number.

To display control numbers in drawings, reports, or when you use the Tools > Inquire > Object command, select the property, ACN.

in the Drawing Manual.

Locking and unlocking control numbers

To prevent Tekla Structures from renumbering the control numbers of all parts in the model, or of specific parts, use the Lock/Unlock control numbers tool.

To lock or unlock control numbers:

1. Click Drawings & Reports > Numbering > Lock/Unlock control numbers:

•       To lock or unlock the control numbers of specific parts, select the parts in the model.

3.     Select Lock or Unlock in the Status list box.

4.    Click Apply, then Create.

The user-defined attribute ACN_STATUS tells you if a part's control number is locked or unlocked.
