Worlds are created in the programmer and stored in the world pool.

Worlds may be thought of as matrix with rows (fixtures) and columns (attributes), and being in a world may block programmer access to rows and/or columns in sheets. 

The created world will contain the rows of the current fixture selection and the columns of any active attribute. All columns/attributes are included in the created world if no attributes were active. If no fixtures were selected, then all fixtures are a part of the world. 

Worlds from the world pool can also be used for sheet masking. For more information read the [Sheet Masking](/grandma3/2-3/worldfilter_filter_rules/) topic.

## Examples

**Requirement:**

Have a world pool and [fixture sheet](/grandma3/2-3/operate_fixture_sheet/) visible on a screen.

### Create a World with Fixture 1 to 5

1. Clear the programmer.
2. Select fixtures 1 thru 5 (or any 5 fixtures in your show).
3. Press Store followed by an empty world in the **World Pool**.
4. Tap the newly created world.

Now there is only programming access to fixtures 1 thru 5, reflected by the fixture sheet. All attributes are available.
