Applying Adornments to a Selection
Labels, diagrams and contours may be applied to all currently displayed entities (i.e. nodes or elements) or they may be applied to a selection set. Once applied to a set that set is preserved with the adornment. Changing the selection set has no effect on the entities to which currently displayed adornments are applied. This allows, for example, bending moment diagrams to be displayed on one set of elements and shear force diagrams to be displayed on a different set.
