Pinch
Squeeze the selection down to one point in the middle.
Pinch squeezes the selection down to one point in the middle. Pick sets the kind it works on: Faces, Rings, or Corners. Pinch is under Size on the Adjust tab.
- Faces: Selected faces squeeze to one point in the middle. Pinching the top face of a cube makes a pyramid roof. Pinching a patch on a sphere squeezes it to a flat point (use Pull out first for a pointed horn). Separate face groups each squeeze to their own point.
- Rings: Each selected ring squeezes to its own point in the middle.
- Corners: Two or more selected corners join into one corner at their middle.
Pinch has its own button in the tool panel, not on the Steps card. One tap does it. After that, the selection clears on its own. When Mirror is on, the matching faces, rings, and corners on the other side pinch too, and one Undo undoes both sides. If the other side does not match, only your side pinches, and the status strip reads Mirror found no matching spot on the other side: this shape isn’t symmetric there. A corner on the mirror line pinches together with its match, to one point on the line.
Pinch on Faces needs a solid part. On a flat 2D sheet it shows a message; use Pull out first to give the sheet thickness.
