Everything it does

Automatic parts detection

• Shape-aware parts. Redrawn live as you slide.

• Snap To Creases. Pulls each boundary onto the real creases.

• Merge, brush, lasso, box. Repaint any boundary by hand.

• Through and Fill Gaps. Paint the faces hidden behind the model without X-ray, and the ones a stroke missed.

• Add A Part. Plant a part the analysis missed.

• Subsplit A Part. Re-analyse the torso, leave the rest alone.

• Parts From Materials. Take the parts from the model's materials or a colour attribute. The model needs several materials: one textured material will not split.

Seams

• Editable curves. Drag, add and drop points in the viewport.

• Flatness and Tilt U/V. Pull the seam onto a flat mating plane. Prints and glues better.

• Detail. Keep the boundary's natural wander, or smooth it.

• Draw Seam Line. Draw across an arm, get a seam.

• Seam From Loop. Hover a ring round an arm, click, get a seam. Shift+Wheel turns it, Ctrl+Shift+Wheel leans it.

• Follow groove. G makes the ring follow the fold under the cursor, so the seam hides in the relief. Snap to groove (S) pulls it onto a nearby groove.

• Extrude. Push a seam's cut face into a plug and the pocket it fits, with a draft angle and a clearance, so a nearly flat part such as an eye comes off thick enough to print and glue back.

• Leave Open. Cut without a cut face: one clean edge loop on each piece, to model the joint by hand.

• Copy hand made joint. Model the joint on one side of a cut left open; one click copies it into the other side and closes the cut. Connectors go on a hand-modelled or extruded joint too, and Both Halves puts the matching one on the other piece.

Connectors

• Peg and socket. True millimetres. A push fit, straight home.

• Peg profiles. Rectangle, round (cylinder or cone), D that fits only one way, or dovetail, tapered on two sides and straight on two.

• Magnet pockets. 5×2 to 10×3 mm, or your own.

• Dowel. A round hole in each piece for a pin printed apart. Export writes the pins beside the pieces or into the 3MF.

• Rod Channel. A channel for a reinforcing rod through every piece it crosses, its ends inside the material. The panel gives the rod to cut.

• Ball Joint. A ball on one piece, the socket that grips it on the other: posable parts that hold their pose. Apply can move each part to where it sits once assembled.

• Fill Cut With Connectors. A whole cut in one click.

• Auto Scale. Off by default. Turn it on to keep each one inside both pieces; either way the panel warns when one does not fit.

• Viewport handles. Slide, turn, scale, or size one axis, on a cut's joints.

• Flip. Swap which half carries the peg.

• Presets. Save your own, apply them anywhere.

Printer

• Your printer. Over 120 models built in, or your own build volume. Each piece shows whether it fits.

• Print View. The pieces packed onto as few plates as they need, in their print pose. Nothing in the scene moves.

Check and export

• Explode and Reassemble. The check that proves the joints seat.

• One STL per piece, or a 3MF per plate. Millimetres, with a filename template.

• Lay flat on the cut. Each piece written resting on its cut, or in the pose Print View shows. Export names any piece too big for the printer.

• Make Manifold. Welds open seams and fills holes before you cut. Hollow models stay hollow.

• Undo Last, Restore Original. Esc stops a long scan, propose, cut or split.

• Saved in the .blend. Reopen tomorrow and carry on, uncut seams included. Rename, duplicate, separate or join pieces and their connectors follow.

• Simple mode. Every stage's basic controls in one panel; switch to the full sidebar when you need more.
