Modeling the sci-fi rings with modifiers

Let's dive in deeper with modifiers. These fictional levitation rings can be made entirely with modifiers (after we add the initial primitive shape); we won't even have to enter Edit Mode! First off, let's create a cylinder:

3. Click the little arrow to expand the Adjust Last Operation panel.
4. Set Radius to 0.97 m.
5. Set Depth to 0.09 m.
6. Set Cap Fill Type to Nothing.
7. Set Location X to 0.0 m.

9. Set Location Z to 0.45 m.
10. Rename the cylinder Chair_Rings.
