Unfold polybeams in drawings

When you create a drawing, you can automatically unfold polybeams and bent plates in single-part drawings. Tekla Structures unfolds the polybeams according to unfolding parameters, which define the location of the neutral axis when a profile is unfolded.


  • You can unfold only beams that have been created with the Polybeam command. You cannot unfold beams created with the Curved beam command.

  • You can unfold 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.

    only on one plane.

  1. On the Drawings & reports tab, click Drawing properties > Single-part drawing .

  3. Click View creation in the options tree and go to the Attributes tab.
  4. Set Unfolded to Yes.
