If you've been working in 3D view in Photoshop and need to switch back to 2D view or want to close the 3D view altogether, you can easily do so by following these steps.

To exit 3D view in Photoshop, simply go to the '3D' menu located at the top of the screen. From the dropdown menu, select 'Disable 3D', and this will switch the canvas back to 2D mode. Alternatively, you can also press 'Ctrl + Alt + Shift + D' on your keyboard as a shortcut to exit 3D view.

If you want to close 3D view altogether and remove any 3D layers or objects from your project, you can also go to the '3D' menu and choose 'Scene' > 'Delete 3D Scene'. This will remove any 3D elements from your project and switch the canvas back to a 2D mode.

It's important to exit 3D view in Photoshop when working with 2D images or when you no longer need the 3D functionality. This will prevent any accidental changes to 3D objects and ensure that you can work seamlessly in 2D mode.

Remember, switching between 3D and 2D views is a common task in Photoshop, and knowing how to exit 3D view is essential for a smooth workflow. By following these simple steps, you can easily switch between 3D and 2D modes in Photoshop without any hassle.
