When you use the Cutter tool, its properties and options appear in the Tool Properties view. The four Cutter modes include: Lasso or Marquee, tip style, mouse gesture, and antialiasing.
Lasso and Marquee Modes
When selecting artwork, you can use the Lasso mode to make a freehand selection or the Marquee mode to make a rectangular selection.
When cutting through pencil lines, this option decides what kind of pencil line tips to put at the extremities of the remaining pencil line segments, where they were cut.
By default, this is set to Bevel , which will leave the tip of the pencil line cut at the same angle as your cutter stroke. If you prefer, you can make pencil lines that you split with the Cutter tool have Flat or Round tips instead.
Use Mouse Gesture Cutter Mode
When this option is enabled along with the Lasso selection type, quickly drawing a line with the Cutter tool over a line segment in your artwork will instantly delete it. This can be useful if you want to use the Cutter tool to quickly clean up your artwork.
When working on bitmap artwork, enabling this will smooth the edges of the artwork you cut out, so that they do not appear pixelated.
