Rings

Rings are how the Nudge phase shapes a piece: the closed loops of edges that wrap around it, like a belt around a tube or the rim of a carved hole. Tap the model and the nearest ring lights up butter-yellow. Tap the same spot again to cycle through every ring that touches it; the hint counts along: “Ring 2 of 4 · tap again to cycle.”

With a ring lit you can push it Wider or Thinner , Move it, Tilt it, or Grab several at once and bend. Need a ring where there isn’t one? Slice cuts a new one.

Step size

The Small / Med / Big switch on each action’s view sets how far every press moves things. One press, one step, always on the grid, so a nudge is easy to repeat and easy to reverse.

Rings follow the model

Rings aren’t a fixed grid. Tilt a ring and it’s still a ring: tap it right back up and keep going. That’s what makes curling a tail possible.

Flat sheets have no rings at all. On a sheet the card switches itself to Points , because corners are how sheets reshape.
