Control Vertices Creates a spline by specifying control vertices. Use this
method to create splines of degree 1 (linear), degree 2 (quadratic), degree 3
(cubic), and so on up to degree 10. Adjusting the shape of a spline by moving
control vertices often provides better results than moving fit points.
Object
Converts 2D or 3D quadratic or cubic spline-fit polylines to equivalent splines.
The original polyline is retained or discarded depending on the setting of the
DELOBJ system variable.
Next Point
Creates additional spline segments until you press Enter.
Undo
Removes the last specified point.
Close
Closes the spline by defining the last point to be coincident with the first. By
default, closed splines are periodic, maintaining curvature continuity (C2)
along the entire loop.
Options for Splines with Fit Points
The following options are specific to the fit point method.
Knots Specifies the knot parameterization, one of several computational methods
that determines how the component curves between successive fit points
within a spline are blended. (
