Yes. After cutting, both pieces receive smooth shading with sharp edges automatically preserved (auto-smooth by angle).

Yes. Undo Last Cut reverts the most recent cut, and Delete All Cuts restores the original model. The workflow is backup-based and non-destructive.

Adjust the Clearance value in the redo panel before confirming the joint. Higher clearance = looser fit, lower = tighter. Re-cut with Undo if needed.

One half gets a tapered dovetail peg (male) and the other a matching socket (female) with a built-in clearance gap, so the parts slot together and self-align — ideal for gluing or friction-fit assembly

No. Only the part directly under your drawn stroke is cut. Geometry that happens to lie along the line's extension (other limbs, the torso, etc.) is left completely untouched.

Yes. The cutting is bmesh-based (not a heavy boolean), so it stays stable on dense, multi-million-poly meshes. For the joint step, the Fast and Manifold solvers are recommended for heavy meshes.
