Grouping objects
Creating a group
When drawing complex diagrams, you may find it useful for certain objects to be joined together. You can do so by Grouping them. Select 1 or more items (or text labels) and click the Group objects button.
This creates a group of objects, these objects will always be selected together.
Editing a group
If you need to make adjustments to any of the items inside a group, you will need to first break up the group. Select the group and click Ungroup objects.
After making adjustments to an item, you can then click Regroup objects to restore the group it was part of.
