SOFiPLUS > Prestressing > Shell PT

Creates tendon geometry and assigned tendon by drawing or selecting an existing AutoCAD geometry.

This command offers the user the possibility to create tendons from AutoCAD objects such as lines, polylines, splines and arcs. To define the tendon, the following options are available:

  • Draw a tendon (first point - next point)

  • Select object

  • Pick lines or curves

  • Polygonal mode

  • Set working plan

To modify the tendon elements use the Modify Tendons command (Icon: icon_modify_tendon ).

Note

Merging Slab PT with Shell PT or Beam PT in a drawing is not recommended. Of course Shell PT and Beam PT can be mixed.

During the definition of the tendons geometry the properties are given via a dialog.
