The Knife tool creates two separate objects by cutting the ellipse in half.
The two objects are separated and used to form the top of the screw.
Premium membership lets you access an improved Knife tool known as Knife (Premium) tool. For more information, see “Splitting objects”
on page 179.
Erasing portions of objects
You can erase unwanted portions of bitmaps and vector objects. Erasing automatically closes any affected paths and converts the object to
curves. If you erase connecting lines, you create subpaths rather than individual objects. You can also delete portions of objects, called virtual
line segments, that are between intersections. For example, you can delete loops from a curved line, or you can delete interior lines from
overlapping shapes.
