In some instances, it is beneficial for multiple banded tendon polyline objects, distributed tendon quadrilaterals object, or profile polyline objects to have identical properties. One example is in symmetrical structures, where for practicality the resulting tendon layout and design should also be symmetrical. It might also be desirable for many different profile elevations to be identical for a typical span in a structure. This can be accomplished using Tendon Parameters Groups.

Once groups are created, they can be selected and assigned to any number of their respective object types, at which point those objects will belong to that group. The properties of the banded tendon polyline, distributed tendon quadrilateral, or profile polyline that are in the group will then be controlled by the group properties, allowing multiple object properties to be updated by changing the group property value.

Groups can also be useful for optimization, especially in cases where it may be practical or desirable to optimize multiple objects in unison or to reduce the number of optimizable objects in the problem. See Designing and Optimizing Post-tensioning for additional information.
