A LineString item is made up of vectors (LineString segments), each vector having a vertex point at its beginning and its end. LineString items can consist either of just a single segment, or of a series of connected segments (known as a MultiLineString item).
A LineString item can have curved segments, and can be open or closed. Straight lines, arcs and curves are all examples of LineString items.
LineString items can also be 3D LineString items, i.e. their coordinates can lie in three-dimensional space.
See the LineString command for details of creating the different variations of LineString items.
A Freehand LineString item is created by placing vertices at short time intervals.
See Freehand.
