Save/Recall Selection Save or recall selection states of the model. If the model is altered after a selection state has been saved, the saved selection state will also be altered. After saving a selection state, any new items (joints, members, etc. ) will be set to "selected. " To save a selection state, click Save and provide a name for the saved selection.
