If the selected spline is closed, the Close option changes to Open. If the selected
spline has no fit data, the Fit Data option is not available. Fit data consists of
all fit points, the fit tolerance, and tangents associated with splines created
with the SPLINE command.
A spline can lose its fit data if you
■
Use the Purge option while editing fit data
■
Refine the spline by elevating the order, adding a control point, or changing
the weight of a control point
■
Change the fit tolerance
■
Move a control point
■
Trim, break, stretch, or lengthen the spline
NOTE SPLINEDIT automatically converts splined polylines to spline objects. A
splined polyline is converted even if you select it and immediately exit SPLINEDIT.
Fit Data
Edits fit data using the following options:
Enter a fit data option
[Add/Close/Delete/Move/Purge/Tangents/toLerance/eXit] <eXit>: Enter an option
or press ENTER
NOTE If the selected spline is closed, the Close option is replaced by the Open
option.
Add
Adds fit points to a spline.
Specify control point <exit>: Specify a control point or press ENTER
Specify new point <exit>: Specify a point or press ENTER
Specify new point <exit>: Specify a point or press ENTER
When you select a point, SPLINEDIT highlights it and the next point and
interprets the new point to go between the highlighted points. Use the Undo
option to remove the last point added. Selecting the last point on an open
spline highlights only that point, and SPLINEDIT adds the new point after
the last. If you select the first point on an open spline, you have the option
of placing the new point before or after the first point.
Specify new point or [After/Before] <exit>: Specify a point, enter an option, or press
ENTER
Specify new point <exit>: Specify a point or press ENTER
