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.
To change the number of segments used to fit an existing spline, change
SPLINESEGS and respline the curve. You do not have to decurve it first.
Decurve
Removes extra vertices inserted by a fit or spline curve and straightens all
segments of the polyline. Retains tangent information assigned to the polyline
vertices for use in subsequent fit curve requests. If you edit a spline-fit polyline
with a command such as BREAK or TRIM, you cannot use the Decurve option.
Ltype Gen
Generates the linetype in a continuous pattern through the vertices of the
polyline. When turned off, this option generates the linetype starting and
ending with a dash at each vertex. Ltype Gen does not apply to polylines with
tapered segments.
Reverse
Reverses the order of vertices of the polyline. Use this option to reverse the
direction of objects that use linetypes with included text. For example,
depending on the direction in which a polyline was created, the text in the
linetype might be displayed upside down.
Undo
Reverses operations as far back as the beginning of the PEDIT session.
