 Choose Structure > Edit Spline > Break Segment. The connection to the
previous segment is now broken.
 Add further vertices. All new vertices now belong to the new segment.
 You can create further segments.
 If a spline consists of several segments, then new vertices are always created
from the active vertex. If no vertices are active, then new vertices are generated
at the last-created segment. If several vertices at different segments are active,
new vertices are always generated at the rst-created segment.

Type
Linear
This simplest of all the spline types connects the vertices, which
dene the polygon, with straight, directly connected lines. You can
use these splines to create angular objects or to simulate sharp jerky
movements for animation.
Cubic
This kind of spline has a soft curve between vertices. The interpolated
curve passes directly through the vertices. Looking at the two points
at the top right of the diagram, you can see that the curve bulges
more than is probably required. This behavior is called overshooting,
and it often appears with closed curvatures. This becomes clearer
when you compare this section of the curve with the same section
of the curve with Akima interpolation.
