Group Ungroup Symbols
Overview
Group
Make a window selection of all the items which you wish to group.
Once the window selection is done, click Group, which groups all the selected items into one cluster and they will behave as a single entity.
If you click on the grouped entity in the canvas, a faint white line displays indicating that the entities are grouped.
Ungroup
Select a grouped entity and click Ungroup. This breaks the group and the objects will now behave as separate entities.
