AutoCAD is a powerful CAD software that allows users to create 2D and 3D designs with precision. Viewing designs in 3D can provide a more immersive and realistic visualization of your projects. Here are a few tips on how to effectively view AutoCAD designs in 3D.

1. Navigate to the 3D workspace: To start viewing your AutoCAD design in 3D, switch to the 3D modeling workspace. This will provide you with the tools and interface necessary for working in a 3D environment.

2. Use the ViewCube: The ViewCube is a useful tool for navigating your design in 3D space. It allows you to rotate and orient the view of your drawing with ease. Click and drag the ViewCube to rotate the view, or click on the different faces to quickly change the viewpoint.

3. Utilize the Orbit command: The Orbit command is another handy tool for viewing your design in 3D. Simply type 'orbit' in the command line, then click and drag to freely rotate the view around your design.

4. Adjust the visual style: AutoCAD offers different visual styles that can enhance the appearance of your 3D design. Experiment with different styles such as wireframe, realistic, or shaded to achieve the desired look and feel for your presentation.

5. Set up camera views: To create specific viewpoints for presentations or visualization, set up camera views within your design. This allows you to save and quickly switch between different perspectives of your 3D model.

6. Use the 3D modeling tools: Take advantage of AutoCAD's 3D modeling tools to create and modify your design in 3D space. This includes tools for extruding, revolving, and lofting 2D shapes to create complex 3D objects.

By following these tips, you can effectively view your AutoCAD designs in 3D to enhance visualization and presentation. Whether you are working on architectural designs, mechanical parts, or any other 3D project, utilizing the 3D capabilities of AutoCAD can help bring your designs to life.
