# Using Presentation parts

Many Presentation parts can be used to control or monitor properties of other parts in a scene. Each part listed below has a Part chooser, which lets you create an association between this part and another part in the scene.

Part | Use to control or display:
--- | ---
Number | numeric properties
Checkbox | two-state properties of a part
Drop-down list | any property of a part that has a limited set of values
Edit box | editable text values

Important Presentation parts include:

- The Animation part: for creating and playing animations within your model.
- The Button part: for creating customised buttons within a model.
- The Picture part: for adding an image to a model.
- The Graph part: for measuring varying quantities in a model.
- The Text part and Instructions part: for adding text to a model.

For advanced users Presentation parts may be attached to the part they are monitoring or controlling.
