Cursor Bisect

Cuts the mesh with a plane anchored to the 3D cursor and aligned to the face and edge under the mouse. Snap the cut to vertices, edge midpoints, regular subdivisions or a typed distance from an edge end, then click to cut — stay in the tool and keep cutting. Bevel mode drops two parallel cuts at once, Fill mode cuts at every snap point along the highlighted edge, and new edges can be marked as seam / sharp / crease / bevel weight. Edit Mesh mode.

Hotkey: Not bound by default — assign a key in Preferences › iOps › Keymaps, or run it from the iOps pie / operator search.

Options

• Merge Doubles — merge vertices left close together after the cut, using the merge distance from the preferences.

Tips

• Deforming modifiers (Subdivision, Solidify, Array…) are switched off while the tool runs so you cut the base mesh; they come back on exit.
• Your snap / mark / preview settings are remembered for the next run.
