Create a steel polybeam

A polybeampart of a certain shape that is created as a continuous chain of beams passing through points that the user picks

The segments of the polybeam are straight, but segment intersections can be curved. For example, a beam that follows a zigzag line is a polybeam.

can contain straight and curved segments.

  1. On the Steel tab, click Beam > Polybeam.
  2. Pick the points you want the beam to go through.
  3. Click the middle mouse button.

    Tekla Structures creates the polybeam between the points you picked, using the Steel beam 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.

    . Note that you cannot create a closed polybeam.

  4. If you want to create curved segments, chamfer the corners of the polybeam.

    For example:

Modify steel polybeam properties

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

Steel beam properties

Use the Steel beam properties in the property pane to view and modify the properties of a steel beam, steel polybeam, or curved beambeam that follows the form of an arc

Steel curved beams can be created by picking three points, where a point between the start point and the end point defines the arc. Both steel and concrete curved beams can be created by adjusting radius in beam properties or by using polybeams.

. To open the properties, double-click the steel beam. The file name extension of a beam 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 *.prt.

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





User-definable name of a beam.

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


Profile of the beam.


Material of the beam.


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 beams.

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

Numbering series

Part numbering

Part prefix and start number for the part position number.

Assembly numbering

Assembly prefix and start number for the assembly position number.


On plane

Beam's position on the work plane, relative to the beam's reference line.


Rotation of the beam around its axis on the work plane.

At depth

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

End offset


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


Move the beam end perpendicular to the beam's reference line.


Move the beam end in the z direction of the work plane.

Curved beam


Plane of curvature.


Radius of the curved beam.

Number of segments

Number of segments Tekla Structures uses when drawing the curved beam.



Use to warp beams using deformation angles.


Use to pre-camber beams.


Use to shorten beams in the model. The true length of the beam is decreased in the drawing.



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