The resulting shape consists of one or more
splines whose vertices are coincident with the
vertices in the selected edges. The Smooth
option results in vertices using smooth values,
while the Linear option results in linear splines
with corner vertices.
If the selected e dges are not continuous, or if
they branch, the resulting shape wi ll consist
of more than one spline. When the Create
Shape function runs into a branching ’Y’ in
the edges, it makes an arbitrary decision as to
which edge produces which spline. If you need
to control this, select only t hose edges that w ill
result in a sing le spline, and perform a Create
Shape operat ion repeatedly to make the correct
number of shapes. Finally, use

in the Editable Spline to combine the
shapes into one.
