In Adobe Photoshop, you can rotate and manipulate 3D objects using the 3D tools and properties. Here's how to do it:

1. **Open or Create a 3D Object**:
- To work with a 3D object, you'll need to either open a 3D model file or create one using the 3D features in Photoshop.

2. **Access the 3D Panel**:
- If you don't see the 3D panel, go to "Window" > "3D" to open it.

3. **Select the 3D Object**:
- In the 3D panel, you should see a list of 3D objects and meshes if you've imported or created one.
- Select the 3D object you want to rotate or manipulate by clicking on its name in the 3D panel.

4. **Rotation**:
- To rotate the selected 3D object, use the 3D Rotate tool.
- Click on the "Rotate 3D Object" button in the 3D panel.
- You'll see a gizmo with axes that you can use to manipulate the object.
- Click and drag on the gizmo handles to rotate the object in different directions.

5. **Scale**:
- To scale the 3D object, use the 3D Scale tool.
- Click on the "Scale 3D Object" button in the 3D panel.
- Similar to rotation, you'll see a gizmo with handles that you can use to scale the object.

6. **Move**:
- To move the 3D object, use the 3D Move tool.
- Click on the "Move 3D Object" button in the 3D panel.
- Use the gizmo to move the object along different axes.

7. **Transform Properties**:
- You can also manipulate the 3D object by directly changing its properties in the 3D panel.
- Select the object, and in the 3D panel, you can adjust values like rotation angles, position, and scale.

8. **Camera View**:
- To view and manipulate the 3D object from different angles, go to the "3D" menu and use options like "Rotate 3D Object" or "Pan 3D View."

9. **Render and Lighting**:
- To enhance the realism of your 3D object, consider adjusting lighting and rendering settings in the 3D panel.

10. **Save and Export**:
- Once you're satisfied with the position and orientation of your 3D object, you can save or export it as needed.

Keep in mind that working with 3D objects in Photoshop can be quite detailed and may require some experimentation to achieve the desired results. Familiarizing yourself with the 3D tools and properties, as well as practicing with various 3D models, will help you become more proficient in rotating and manipulating 3D objects in Photoshop.
