Hey there, AutoCAD users! Want to take your designs to the next level by exploring them in 3D? In AutoCAD 2015, changing to 3D view is easy and can open up a whole new perspective on your projects. Here's how to do it:

1. Open your drawing in AutoCAD 2015. If you're not already in model space, switch to it by clicking on the 'Model' tab at the bottom left of the drawing window.

2. Once you're in model space, navigate to the View tab on the ribbon at the top of the window.

3. In the Views panel, you'll see a section labeled '3D Views.' Click on the dropdown arrow next to it to reveal a list of 3D view options.

4. Select the 3D view that best suits your needs. You may see options like 'SW Isometric,' 'SE Isometric,' 'NE Isometric,' and 'NW Isometric,' as well as other custom views. These views will change the perspective of your drawing to give you a 3D representation.

5. After selecting a 3D view, your drawing will instantly switch to that perspective, and you can now explore your design in 3D space. Use the zoom and pan tools to navigate around your model and take in all the details from different angles.

That's it! Now you're all set to switch to 3D view and take your designs to new heights in AutoCAD 2015. Whether you're working on architectural plans, mechanical designs, or any other type of project, exploring your work in 3D can provide valuable insights and help you communicate your vision more effectively.

So, next time you want to see your designs from a different angle, remember these simple steps to change to 3D view in AutoCAD 2015. Keep experimenting with different 3D views to find the one that best showcases your work. Happy designing!
