2.18.9 The “Spiral beam” tool in the Tekla Structures
The “Concrete spiral beam” tool is similar to the “Steel
Tekla Structures v21.1
The present Tekla Structures version is not available on the “Concrete
spiral beam” tool.
Tekla Structures v2021
The algorithm for using the “Spiral beam” tool:
Enable the “Spiral beam” tool.
Indicate by a left-click the starting point of the spiral beam.
Indicate the spiral center coordinate at 5000 mm from its starting point.
Press the mouse wheel button or the "Space" key to finalize
specifying the basic coordinates of the beam. The direction of the rotation
axis shall be perpendicular to the view plane (codirected with the Z-axis).
Press the Esc key to disable the “Spiral beam” tool.

If required, it is possible to twist the spiral beam body around its axis.
In order to get that done, set up the “twist angle at start”

By using the “Spiral beam” tool it is possible to create objects
of a complex shape, such as circular stairs and etc.
