AutoCAD is a powerful software for 3D modeling, and knowing how to change view in AutoCAD 3D can greatly enhance your design experience. Here are a few methods to help you easily change view in AutoCAD 3D:

1. Using the ViewCube: The ViewCube is a handy tool located in the upper-right corner of the drawing area. You can click and drag the ViewCube to rotate the view in the 3D space, or click on the different faces of the cube to quickly change to different standard views like top, bottom, front, back, left, or right.

2. Using the Orbit Tool: The Orbit tool is another way to change view in AutoCAD 3D. You can activate the Orbit tool by clicking on the View tab, then navigating to the 3D View panel and selecting the Orbit tool. Once activated, click and drag in the drawing area to orbit around your 3D model and change your viewpoint.

3. Using the Viewpoint Presets: AutoCAD comes with a set of viewpoint presets that you can use to quickly change view in AutoCAD 3D. You can access the viewpoint presets by clicking on the View tab, then navigating to the Views panel and selecting one of the preset options like SW Isometric, SE Isometric, or Custom View. This can be a quick way to switch between different views without having to manually adjust the view each time.

4. Using the 3DORBIT Command: The 3DORBIT command is another powerful tool for changing view in AutoCAD 3D. You can activate the 3DORBIT command by typing it in the command line, then use the mouse to orbit around the 3D model and change your perspective.

By using these methods, you can easily change view in AutoCAD 3D and improve your 3D modeling workflow. Whether you prefer using the ViewCube, Orbit tool, viewpoint presets, or the 3DORBIT command, there are multiple options to help you navigate and visualize your 3D models more effectively.
