Are you ready to take your AutoCAD 2018 skills to the next level by viewing 3D models? Here's how:

1. Open your 3D model: Start by opening your 3D model in AutoCAD 2018. You can either create a new 3D model or open an existing one.

2. Switch to 3D workspace: Once your 3D model is open, switch to the 3D modeling workspace. This will give you access to the tools and features you need to view and manipulate the 3D model.

3. Use the ViewCube: The ViewCube is a handy tool for navigating 3D models in AutoCAD 2018. It allows you to rotate, pan, and zoom in on your 3D model with ease. Simply click and drag on the ViewCube to change your viewpoint.

4. Explore the 3D tools: AutoCAD 2018 offers a range of 3D viewing tools that can help you analyze and visualize your 3D models. Take some time to explore the various options, such as orbit, 3D rotate, and 3D pan, to find the ones that work best for your needs.

5. Adjust visual styles: To enhance the visual representation of your 3D model, you can adjust the visual styles in AutoCAD 2018. Experiment with different options, such as wireframe, shaded, and realistic, to find the style that provides the most useful view of your 3D model.

6. Use 3D navigation tools: AutoCAD 2018 also offers specific 3D navigation tools, such as the 3DORBIT command, which allows you to orbit around your 3D model, and the 3DWALK command, which simulates walking through your 3D model. These tools can be especially useful for getting a better understanding of the spatial relationships within your 3D model.

With these simple steps, you can start viewing and exploring 3D models in AutoCAD 2018 with confidence. Whether you're a beginner or an experienced AutoCAD user, mastering 3D viewing will open up new possibilities for your design projects.
