Create Spring Structural Elements
The Spring tool recognizes CBUSH connections and absorbs them as springs.
- 
                From the Certification ribbon, click the Spring
                    tool.

                When Structural elements are created, a structural property can be selected.
                    Click 
 to define how properties are assigned.
                Each structural element must have a structural property assigned to it in order to run method.- Single property
 - Assigns the same structuralproperty entity to all designpoints.
 - Duplicate and assign property to all
 - Creates a new instance of the selected structuralproperty and assigns the copy to all designpoints.
 - Duplicate and assign property per designpoint
 - Creates a new instance of selected structuralproperty per designpoint entity.
 - This option performs a deep copy, meaning the structural property's references, such as materiel/property, are also copied. Each structural property generated is fully independent.
 - This is useful for design exploration where you will update structural properties separately.
 
 - Select CBUSH elements to absorb as springs.
 - Optional: 
                Select a destination DesignPointSet to hold newly created designpoints.
                If no set is selected, a new one is created with config Spring.
If you enter this menu from the Certification Browser context menu using Auto DDP, the selector is pre-populated with the selected designpointset.
 - Specify a structuralproperty entity to assign.
