IMPORTANT Switching from displaying control vertices to fit points automatically
changes the selected spline to degree 3. Splines originally created using
higher-degree equations will likely change shape as a result.
In general, editing a spline with control vertices provides finer control over
reshaping a small section of the curve than editing a spline with fit points.
You can insert additional control vertices to a section of a spline to obtain
greater control in that section at the expense of making the shape of the spline
more complicated. The Refine option adds a knot to the spline resulting in
replacing the selected control vertex with two control vertices.
Edit Splines with SPLINEDIT
SPLINEDIT provides additional editing options, such as adding a kink to the
spline, and joining a spline to another contiguous object, such as a line, arc,
or other spline. As shown, objects are joined to splines with C0 continuity.
