Make a part

Pick Rectangle, Circle or Pen, then drag on the grid or on a flat face (or tap one first, then use Sketch in the bottom row). The view turns square-on to that plane so you can draw like in a vector editor: drag a shape, or tap to place one and type its size. With the Pen, click for a corner point and click-and-drag for a smooth curve; tap a point to bend it, turn it smooth or sharp, or type exact values. Tap OK to return to 3D: the sketch is saved in History as its own step, then set the distance and extrude. Cancel keeps the sketch (its blue outline) so you can tap it later to Extrude or Edit it, and a sketch can be extruded as many times as you like; editing the sketch step updates every extrude made from it.

Move around

One finger orbits, pinch zooms, two fingers pan. With Finger drawing on, one finger draws instead; use Select to pan. Two-finger tap undoes, three-finger tap redoes. Tap the cube to snap to a view.

Selecting

The arrow beside Select chooses what a tap picks: Auto, whole Body, flat Face, or Edge. Keys: B, F, E.

Change a shape

Tap a face to push or pull it, sketch on it, or add a joint. Tap an edge to chamfer or fillet it. Tap the same face or edge again to grow the selection to its neighbours, or use Add mode (or Shift-click) to pick several. Tap ✎ Edit in the history to change an earlier step.

Parts that fit

Gears makes involute spur, helical, herringbone, internal and rack gears and places a meshing mate at the exact centre distance. Select a gear and tap Mate gear to add a meshing gear: pick a ratio (2:1, 3:2 and so on), drag the blue ghost round the dashed circle, and the teeth line up for you. Use Spin test to watch them mesh, and mate again from the new gear to build a train. The Mechanisms menu adds a pin hinge, living hinge, snap hook and catch, flexure slide, dovetail or groove. The flexing ones are sized from your material (PLA, ABS, PETG or TPU in Settings): ask for the flex you need and leave length or thickness at 0 to have them worked out, and use the Flex slider to watch the part bend before you place it. Fit adds the right gap between a rod and its hole (Press, Snug, Slide or Loose, from your material), and the check mark shows a count when parts touch or are too tight; a part's own fit gap can be set in Style. Combine merges two parts or cuts one with another, which is how you join a flexure to your own parts. Socket mode cuts a matching hole. Move and Rotate show arrows and rings on the part to drag (or type exact values); Duplicate adds moved copies. Slice cuts a part with a plane, for printing in halves: drag the orange arrow to move the plane and the rings to tilt it, flip which half is above, add alignment pegs and matching holes, and lay both cut faces on the bed. Shell hollows a part with walls of the thickness you choose; tap faces first to leave them open as the entrance, or leave none for a sealed hollow part. Align, Mirror and Pattern place parts; Lock protects one.

The toolbar

Tap a part, face, edge or the ground and the row at the bottom shows what you can do with it. Scroll it sideways for more. While an action is open its settings replace the row, so only one thing sits over the model. Settings (the sun icon) has Light, Dark and Auto.

Before you print

The check mark finds overlaps, tight gaps and thin walls. The triangle shows overhangs; Auto-orient picks the best way up. Export 3MF to keep separate parts in PrusaSlicer.
