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.

On the right side of the screen, click the lasso.

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, "Create Entity Set."

Notice, all the selected entities are listed.  Name the entity set and click "Create."

A confirmation will appear in the bottom right corner that the set was created.

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

The Entity Set will also be available for Scripts.
