Modify Splines
In addition to the general editing operations available for most objects, there
are additional options available for editing splines with
SPLINEDIT.
Fit Data. Edits the fit point data that defines the spline, including
changing the tolerance.
Close. Changes an open spline into a continuous, closed loop.
Move Vertex. Moves a fit point to a new location.
Refine. Modifies a spline definition by adding and weighting control
points and elevating the order of the spline.
Reverse. Changes the direction of the spline.
You also can change the tolerance of the spline. Tolerance refers to how
closely the spline fits the set of fit points you specify. The lower the tolerance,
the more closely the spline fits the points.
Edit Splines with Grips
When you select a spline, grips are displayed on its fit points (the
GRIPS
system variable must be set to 1). You can use grips to modify the shape and
location of the spline.
After certain operations, fit points are discarded and grips are displayed on
control points instead. These operations include trimming the spline, mov-
ing the control points, and purging the fit data. If the spline's control frame
is turned on (the
SPLFRAME system variable is set to 1), grips are displayed on
both the spline's control points and its fit points, when available.
