Knife Tool

The following settings can be adjusted from the context toolbar:

Straight Line—when enabled, a straight knife stroke can be drawn across your object from a fixed position.
Auto close—choose from the following options:
- Close off—when enabled, you can continue applying strokes without closing the curve when the cursor approaches close to the same curve's start node; opposite to the "Close always" option.
- Close near—when enabled, you can close the curve when the cursor approaches close to the curve's start node.
- Close far—when enabled, you can close the curve when the cursor's position is further from the curve's start node.
- Close always—when enabled, the curve is always closed, irrespective of the distance between the end points.
Stabilizer—enables stroke stabilization using either a Rope stabilizer or Window stabilizer mode.
- For rope mode—drag the stroke end by a 'rope' to smooth the stroke but introduce sharp corners at increasing rope Length (radius) values by redirecting the slackened rope. Set value via vertical slider.
- For window mode—smooths the stroke by averaging sampled input positions within a Window whose size is configurable. Set value via vertical slider.

The following setting can be adjusted via the vertical slider:

Smoothness—depending on the qualities of the initial stroke, you can fine-tune its curvature (or jagged nature) by setting the value.
