Node Specification dialog
Used to specify rigid links or specialized linkages in the structure. This facility can be used to model special structural elements such as ties or a floor diaphragm which makes the floor rigid for in-plane movements. The process is to select a node to act as the control and then degrees of freedom for which the dependent nodes are linked to the control.
Opens when Node is clicked on the Specifications - Whole Structure dialog.
