Create a twin profile

A twin profilepart that represents two identical parts mirrored in relation to their position

Twin profile can be separated into two individual parts, after which it is no longer a twin profile.

consists of two parallel and identical beams. You define the positions of both beams by selecting the twin profile type and setting the clearanceset space between objects

In bolted connections, clearance is required for entering and tightening the bolts with an impact wrench. In addition to this, there may be a clearance for a fillet.

In welded connections, clearances are required in order to allow a welder to lay a correct weld.

Reinforcing bar clearance defines the minimum clearance or the allowed overlap for reinforcing bars when they are checked against other objects.

between the beams in two directions.

  1. On the Steel tab, click Beam > Twin profile.
  2. Pick two points.

    Tekla Structures creates the twin profile between the points you picked, using the Twin profile properties in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

    The property pane can be used to show and modify the properties of model objects.

    The property pane can be customized by using the property pane editor.


Alternatively, you can start the command in the property pane.

  1. Ensure that you have nothing selected in the model.

  2. In the property pane, click the Object type list button and select Twin profile from the list.

    Tekla Structures starts the command and shows the properties in the property pane.

Modify twin profile properties

  1. If the property pane is not open, double-click either of the beams to open the Steel beam properties.
  2. Change the properties as needed.
  3. Click Modify .

Twin profile properties

Use the Twin profile properties in the property pane to view and modify the properties of a twin steel profile. The file name extension of a twin profile property fileobject type specific file that contains values of properties or settings used in the property pane or a dialog box

Property files are saved in the current model folder. The user can create and modify property files and copy them to the project or firm folders for future use.

User-defined attributes related to a specific object type are stored in a separate property file.

is *.dia.

If you have customized the property pane layout, the list of properties may be different.





User-definable name of a twin profile.

Tekla Structures uses part names in reports and in Document manager, and to identify parts of the same type.


The profile of both the beams in the twin profile.


Material of the beams.


Type of finish.

Finish is user definable. It describes how the part surface has been treated, for example, with anti-corrosive paint, hot galvanized, fire retardant coating, and so on.


Use to group twin profiles.

For example, you can display parts of different classes in different colors.

Twin profile type

Define how the profiles are combined.

Numbering series

Part numbering

Part prefix and start number for the part position number.

Assembly numbering

Assembly prefix and start number the assembly position number.


On plane

Twin profile's position on the work plane, relative to the twin profile's reference line.


Rotation of the twin profile around its axis on the work plane.

At depth

Position depth of the twin profile. The position is always perpendicular to the work plane.

End offset


Change the length of the twin profile by moving the twin profile end point along the twin profile's reference line.

Clearance between members


The horizontal clearance between the profiles.


The vertical clearance between the profiles.



Click the User-defined attributes button to open the user-defined attributes (UDAs) of the part. UDAs provide additional information about the part.
