AutoCAD provides powerful tools for 3D modeling and design, and being able to change the 3D view is essential for efficient work. Here’s how to do it:

1. Orbit Tool: Use the Orbit tool to rotate the 3D view in any direction. Simply select the tool and drag the mouse to rotate the view.

2. 3D Viewing Cube: The 3D viewing cube located in the top-right corner of the workspace allows you to easily change the 3D view by clicking on the faces, edges, or corners of the cube.

3. ViewCube: The ViewCube is another tool for changing the 3D view. It provides a quick and easy way to orient the view in 3D space and includes options for rotating and orienting the view.

4. Visual Styles: AutoCAD provides different visual styles for viewing the 3D model, such as wireframe, realistic, and conceptual. Changing the visual style can also impact the way the 3D model is viewed.

5. Camera Views: Use the predefined camera views, such as top, front, bottom, left, right, etc., to quickly change to standard viewing angles.

By mastering these techniques, you can efficiently navigate and change the 3D view in AutoCAD, making 3D modeling and design tasks much easier and more intuitive.
