SPLINEDIT
Modifies the parameters of a spline or converts a spline-fit polyline to a spline.
Access Methods
Menu: Modify  Object  Spline
Shortcut menu: Select a spline to edit. Right-click in the drawing area and
click Spline.
Summary
Modifies the data that defines a spline, such as the number and weight of
control vertices, the fit tolerance, and the starting and ending tangents.
NOTE SPLINEDIT automatically converts spline-fit polylines to splines even if you
immediately exit SPLINEDIT after selecting the spline-fit polyline.
The data that defines a spline is represented in one of two formats: as a control
frame or as fit points. The format can change depending on how the spline
was originally created, the options selected from the grip menus, or the options
used in SPLINEDIT.
You can change any of following data:
 Control frame data consists of control vertices, the polynomial degree of
the spline, and the weights assigned to each control vertex.
 Fit data consists of fit points, knot parameterization, the fit tolerance, and
the tangents at the endpoints of the spline.
NOTE 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 addition, if the spline was created
using a positive tolerance value, the fit points will be relocated to the knots on the
spline, and the tolerance value is reset to 0.
