Face ‣ Intersect (Knife)

The Intersect tool lets you cut intersections into geometry. It is a bit like the Boolean tool, but, does not calculate interior/exterior geometry. Faces are split along the intersections, leaving new edges selected.

Source

Selected/Unselected

Operate between the selected and unselected geometry.

Self Intersect

Operate on the overlapping geometry of the mesh.

Separate Mode

All

Splits the geometry at the new edge.

Cut

Keep each side of the intersection separate without splitting the faces in half.

Merge

Merge all the geometry from the intersection.

Merge Threshold
