Percent
From left to right: the effect of increasing the Percent value.
The Percent value denes the strength of smoothing. A value of 0% results in no smoothing at all,
while a value of 100% produces maximum smoothing.
Knife
The Knife tool allows you to cut polygon objects and spline objects. The tool works in all three modes
(point, edge and polygon).
When you are cutting polygons, there are many parameters you can adjust to precisely control the
cut. The Knife cuts the polygons by creating new points and edges along the cutting line. If you’ve
made a selection, the cut will be restricted to the selection.

Mode
Line mode
In Line mode, you can drag a cutting line over the polygons.
You may nd it helpful to think of this cutting line as being
a red hot wire that cuts straight through the polygons.
Press Shift to constrain the cutting line to the Angle value
(Single must be enabled).
