How do I create an Entity Set from a selection in Maps?

PetroVisor has the ability to lasso Entities in Maps to create an Entity Set.

Select Maps from the Navigation panel.

At the top of the screen, click the selection.

After clicking, it will show highlighted.

Click the screen and start drawing a perimeter around the entities to create the set.

Once the perimeter is complete, a pop-up will appear at the bottom of the screen.  It shows the number of Entities Selected.  

To cancel, click the "X" at the top right of the pop-up.  To create the set, click the green button.

Notice, all the entities are listed in the select.  Name the set and click "Create."

The Entity Set will be available in the drop-down menu.

The Entity Set will also be available for Scripts.
