Pull out

Pull out pulls faces outward, the way each one faces. The main switch sets the selection mode: Tap faces or Draw a shape. Pull out is under Surface on the Build tab.

Tap faces

Select faces using Select , then select Pull out. Use Size (Small, Medium, or Big) to set the distance per press (default: Small). The text shows the selection. Pulled faces stay selected, so each press pulls them out further. If Mirror is on, matching faces on the other side pull out too.

Faces sets the pull mode for selected faces. Each (default): every face pulls straight out its own way, with its own side walls. Together: selected faces that share an edge on one part pull out as one piece, with walls only round the outside, so a box corner fills out square and a ring round a cylinder becomes a wider ring. A face that shares no edge with another selected face pulls as it does on Each. If the faces would fold over or close up, nothing changes and the status line reads No room to pull the faces as one. Try Each, or a smaller step. With Mirror on, the faces and their mirror twins pull together, so a face on the mirror line joins both sides alike. Push in has no Faces row: it already pushes in touching faces as one dent.

Using Pull out on a flat sheet (e.g., a Sheet shape or a flat drawn shape ) adds sides to make it solid. On curved surfaces, each face pulls out the way it faces, so the surface grows to match.

Used on the floor of a dent made with Push in , Pull out raises the floor step by step. When the floor lines up with the surface around it, the dent closes flush.

Draw a shape

Switch to Draw a shape and tap a face to show a dot grid. Dots sets the dot spacing: ½ (default), ¼, or ⅛ block. It keeps your setting until you close the app (Push in shares it), and it is hidden once the shape is closed. A coarser spacing can’t be selected while placed dots aren’t on it. Tap dot to dot to draw a closed shape, tapping the first dot to close the loop. A finger on the fig shows the dot a tap would place (a ring, and a dashed line from the last dot). Hold still for a moment to aim: drag to the dot you want and lift to place it. Use ↩ Undo dot to take back the last dot (on a closed shape it opens the loop again), or ✕ Start over to clear the shape. The Undo button also undoes dots while you draw. Before the first dot, tapping another face moves the dot grid there. Once you start placing dots, tapping another side keeps the grid in place and shows A shape stays on one flat side. Tap dots on this side, or press Start over.

Closing the loop turns on the Height stepper. Set the height with − and +, then select Pull it out. The shape rises out of the surface, joined to the part.

Drawing rules:

• Lines can’t cross.
• On flat faces, shapes can run along the face’s edges, in one stretch only (never at just one dot). An outline that is the whole side is refused: use Tap faces for that. Shapes that cross fine-grid lines keep the face colors on their new sides.
• Faces too small for grid dots can’t be drawn on.
• On curved surfaces (cylinders, spheres, tubes), grid dots follow the curve at the Dots spacing. Drawing on a curve needs a smooth curve across the faces next to each other. Where two faces meet at a crease, each face gets its own flat grid.
• When Mirror is on, shapes on flat faces are copied and pulled out on the other side too; shapes on curved surfaces are not mirrored. When only one side can be made, the status strip shows the reason (Mirror found no matching spot on the other side: this shape isn’t symmetric there or Mirror can’t copy shapes on round surfaces yet, so the shape is on one side only.) until your next action. A shape centered on the mirror line is made once; it is its own mirror.

Limits

If pulling out would go past the edge of the workspace, it is blocked and a message shows (No room: you’re at the edge of the world). A pull stops when it runs into the same part, sealing flush against the faces it touches. A pull that can’t be done shows a message with the reason.
