Yes, but you still got it wrong on a matter of principles: you know a
torus is the result of rotating a circle around an axis, you knew I told
you about the very useful spin button, and yet you felt like it'd be fun
to try to make it out of a hole through a box. Doesn't make any sense.

Povray SDL is more well suited for math surfaces, you'll be boring
yourself with a mesh editor for that.

a either selects all or unselects all in case there's anything selected.
ctrl+i inverts a selection.

Cuts don't really work fine in mesh editors.

Sure you know, I told you how to to so before: when either in top, side
or front view, select a single vertice and go ctrl+LMB clicking
throughout the viewing plane. Each ctrl+click will automatically
extrude each vertice/edge/face. Have you actually managed to get your
belt this way?
