To modify a polyline
1 Click Home tab ➤ Modify panel ➤ Edit Polyline.
2 Select the polyline to modify.
3 If the selected object is a spline, line, or an arc, the following prompt is
displayed:
Object selected is not a polyline.
Do you want it to turn into one? <Y>: Enter y or n, or press Enter
If you enter y, the object is converted into a single-segment 2D polyline
that you can edit.
Before the selected spline is converted to a polyline, the following prompt
is displayed:
Specify a precision <10>: Enter a new precision value or press Enter
The PLINECONVERTMODE system variable determines whether the
polylines are created with linear or arc segments. When the PEDITACCEPT
system variable is set to 1, this prompt is suppressed, and the selected
object is automatically converted to a polyline.
4 Edit the polyline by entering one or more of the following options:
■ Enter c (Close) to create a closed polyline.
■ Enter j (Join) to join contiguous lines, splines, arcs, or polylines.
■ Enter w (Width) to specify a new uniform width for the entire polyline.
■ Enter e (Edit Vertex) to edit a vertex.
■ Enter f (Fit) to create an arc-fit polyline, a smooth curve consisting of
arcs joining each pair of vertices
■ Enter s (Spline) to create an approximation of a spline.
■ Enter d (Decurve) to remove extra vertices inserted by a fit or spline
curve and to straighten all segments of the polyline.
■ Enter L (Ltype Gen) to generate the linetype in a continuous pattern
through the vertices of the polyline.
■ Enter r (Reverse) to reverse the order of vertices of the polyline.
