Points are single elements with no area or dimensions, that exist in pattern pieces or on line segments. Points control the shape of line segments, how stitch artwork is displayed on lines or edges, and can be stitched to. Points cannot exist outside of pattern pieces.
In VStitcher, you can edit pieces by dragging points. You can also edit and configure points to specify their behavior. For example, you can make a point a corner point, or use it to add a notch.
