Definition of the geometry, element assignment and stressing actions of tendons. Certain sets of corresponding tendons are combined in different groups (i.e., for various spans or recurrent sections of spans respectively). Group names are defined in Group name and generated groups can be selected by clicking on the arrow. New groups can be added (before or after the selected one) or be deleted by clicking on the respective icons in the upper part of the window. The copy icon will copy the selected tendon group to an existing group that can be selected from a list (and will be replaced then) or to a new one that can be generated and will be inserted at the end. The maximum number of tendon groups is 128.

For a reasonable and efficient use of tendon groups and the principle behind the tendon definition in Cantilever itself refer to the Cantilever Manual.

Undo and Redo will undo the last action (or undo the last undo respectively).
