Only Edges (all modes)
If this option is enabled, only the edges will be cut. The polygons themselves will not be cut (provided
Create N-gons is enabled).
Visible Only (all modes)
Enable this option to cut directly visible polygons only. Otherwise, polygons at the back of the object
— or even other selected polygon objects out of sight behind the object — will be cut.
Create N-gons (all modes)
N-gons will be created automatically if this option is enabled and the resultant polygons have more
than four corner points. If you want each polygon to be triangulated automatically instead, disable
the option.
Constrain, Angle (Line mode)
The Constrain option, if enabled, will constrain the cutting line angle to the Angle value. You can also
constrain the cutting line angle by holding down Shift while you make the cut.
Offset (Plane, Loop and Path modes)
In Plane mode, Offset denes the position of the cut.
In Loop mode, Offset denes the cut position along the selected edge (mouse position).
In Path mode, Offset denes the cut position along the width of the cut.
Keep Lock (Plane, Loop and Path modes)
If this option is enabled, you can lock the cutting line in place by pressing Shift. Then, as you adjust
the knife’s parameters, the cutting line will be updated in realtime.
