Hole mode
Hole mode allows you to cut a hole inside an individual
polygon, which is highlighted in yellow. Click in each
position where there should be a corner point, then click
again on the rst corner point to complete the cut.
Plane mode
This mode gives you an easy way to make cuts along a
plane. You can make a single cut or even carve up the entire
object. You can dene the number of cuts and the distance
between each cut.
Loop mode
The Loop mode enables you to subdivide edge loops. Move
the mouse pointer to the position along one of the edges
that the new loop should cut through. A yellow preview will
appear to indicate where the new cut will be placed. Click
to apply the cut.
Path mode
This mode requires an edge selection or polygon selection.
Move the mouse pointer in the area of the selection. ‘Path’
will then attempt to cut a path (displayed as a yellow
preview) through the selection. For best results, select a
path of polygons one polygon wide.
Single (Line mode)
If this option is enabled, you can choose both the start point and end point of the cutting line. If the
option is disabled, the end point of the last cut will automatically become the start point of the next
cutting line.

If this option is enabled, the Knife tool will cut the selected elements only.
Select Cuts (all modes)
Selects the edges of the new cut. To add the new edges to the existing selection, hold down Shift
