Stack Stack phase

Move, Size & Turn

Tap a placed piece to step it around, stretch it, spin it, or trash it.

Tap any placed piece and the Object card opens: a name field, Move, Size, Turn, Duplicate, Mirror a copy, and Trash.

The Object card. Move, Size, and Turn each flip to a set of step rows.

Name it

The card’s name field names the piece: “left arm”, “tail”, “hat”. Names show up wherever pieces are listed, so a build with many parts stays findable.

⤢ Front+
↕ Up+
Tapping Move flips to these rows. Size and Turn work the same way.

Move

Steps the whole piece through the world, one press at a time. Pick a step (Small, Med, or Big), then press − / + on the three direction rows. Ünflat never says X, Y, or Z: directions are always ↔ Side, ⤢ Front, and ↕ Up.

Size

Stretches or shrinks the piece along Width, Height, and Depth, with the same Small / Med / Big steps.

Turn

Spins the piece in 15°, 45°, or 90° notches around any of the three directions. 90° is the default; the smaller notches are for tilted heads and A-poses. Turned pieces snap back onto the grid and lift themselves off the floor so nothing ends up buried.

Duplicate

Drops a fresh copy of the piece one block clear of the original and makes the copy the card’s target, ready to Move into place.

Mirror a copy

Duplicates the piece flipped across the middle of the model. Sculpt one arm, press Mirror a copy, and the matching arm appears on the other side. Arms, legs, ears, and eyes all come in pairs; you only ever build one.

Trash

Deletes the piece. It asks first, and Undo brings it back.

Size and Turn reshape the piece, so if it already has poses , the app warns you before a change that would erase them.
