The Join option of PEDIT decurves the spline and discards the spline
information of the original and any added polylines. Once the Join operation
is complete, you can fit a new spline to the resulting polyline.
The Edit Vertex options of PEDIT have the following effect:
 The Next and Previous options move the X marker only to points on the
frame of the spline, whether visible or not.
 The Break option discards the spline.
 The Insert, Move, Straighten, and Width options automatically refit the
spline.
 The Tangent option has no effect on splines.
Object snap uses only the spline-fit curve itself, not the frame. If you want to
snap to the frame control points, use PEDIT to recall the polyline frame first.
The
SPLINETYPE (page 1446) system variable controls the type of spline curve
approximated. Setting SPLINETYPE to 5 approximates a quadratic B-spline.
Setting SPLINETYPE to 6 approximates a cubic B-spline.
You can examine or change the fineness or coarseness of the spline
approximation with the
SPLINESEGS (page 1446) system variable, or you can
use AutoLISP
®
. The default value is 8. If you set the value higher, a greater
number of line segments are drawn and the approximation to the ideal spline
becomes more precise. The generated spline occupies more space in the drawing
file and takes longer to generate.
If you set SPLINESEGS to a negative value, the program generates segments
using the absolute value of the setting and then applies a fit-type curve to
those segments. Fit-type curves use arcs as the approximating segments. Using
arcs yields a smoother generated curve when few segments are specified, but
the curve can take longer to generate.
