At 7:40, Rick Casually clicks on the cube gizmo and scales the face loop evenly.
The problem is I can’t recreate this effect.
Instead, scaling like this just deforms the face ring into one direction.
In the attached picture, I end up with A shorther than B.
The gizmos are tricky to understand. If you look at it (in your screenshot) you will see that there are little cubes at the ends of each axis. If you click on those and drag, it scales along the axis the little cube is attached to.
Now, you’ll also notice a little cube in the middle of the gizmo. If you click and drag on this little cube, it scales on all the axes evenly.
