Floor Sketches with Multiple Boundaries

One way to solve this, is to split your floor boundaries into two non-overlapping loops. In the case of a torus, that would be two C-shapes.

Visually it will look like one floor, however editing it manually later on would be more challenging, because you’d have to edit each half individually. I think I saw this approach first from Brian Ringley.
