# Using mechanisms parts

Mechanical systems can be created using a combination of mechanical parts and electromechanical parts (e.g., generator or electric motor).

See Connecting mechanisms and Adding movement to mechanisms for details on creating mechanical systems.

Key points:

- Mechanisms parts can only be added to 3D spaces (Mechanisms and PCB). Mechanical parts appear in 3D only; electromechanical parts are represented in 2D and 3D.
- In 3D, these parts snap to the workplane. You can build up from this plane by changing the orientation of parts then extending shafts.
- Change the orientation of mechanical parts using the buttons in the Properties pane.
