When working with AutoCAD, you may encounter situations where you need to view 2D objects in 3D. This can be a valuable skill to have, especially when you need to visualize how 2D drawings will appear in a 3D environment. Fortunately, AutoCAD provides several tools and features that make it easy to view 2D objects in 3D.

Here are the steps you can follow to view 2D objects in 3D AutoCAD:

1. Use the ViewCube: AutoCAD's ViewCube is a navigation tool that allows you to rotate and orient the view of your drawing in 3D space. By using the ViewCube, you can easily switch between 2D and 3D views, and quickly navigate around your drawing to see it from different angles.

2. Turn on the 3D Orbit: The 3D Orbit command allows you to rotate the view of your drawing freely in 3D space. You can activate the 3D Orbit by clicking on the 3D Navigation bar at the bottom of the drawing window, or by using the '3DORBIT' command. Once activated, you can orbit, tilt, and pan the view to get a 3D perspective of your 2D objects.

3. Use Visual Styles: AutoCAD provides various visual styles that can help you view your 2D objects in 3D. By applying visual styles such as Conceptual, Realistic, or Shaded, you can enhance the appearance of your 2D objects and make them look more three-dimensional.

4. Create 3D Views: You can create custom 3D views in AutoCAD to display your 2D objects in a 3D context. This allows you to save specific viewpoints and switch between them as needed. To create a new 3D view, use the '3DVIEW' command and set the desired orientation and perspective for your 2D objects.

By following these steps and utilizing the tools provided by AutoCAD, you can easily view 2D objects in 3D and gain a better understanding of how your drawings will look in a three-dimensional space. This can be particularly useful for architects, engineers, and designers who need to visualize their 2D designs in a 3D environment before finalizing their projects. With a little practice, you'll be able to seamlessly transition between 2D and 3D views in AutoCAD and effectively communicate your design intent.
