tangent to the end of the spline (C1 continuity). If the shape of the spline is
later changed, the tangency of the linear portion is not maintained.
Trimming a spline shortens it without changing the shape of the portion that
remains.
Filleting a spline creates an arc that is tangent to the spline and the other
selected object. The spline might be extended with a linear portion to complete
the fillet operation.

NOTE Because periodic curves and surfaces are not currently supported, the objects
may kink if they are reshaped.
