Joined Polyline Segments
You can join a line, an arc, or another polyline to an open polyline if their
ends connect or are close to each other. If the ends are not coincident but are
within a distance that you can set, called the fuzz distance, the ends are joined
by either trimming them, extending them, or connecting them with a new
segment.
Properties of Modified Polylines
If the properties of several objects being joined into a polyline differ, the
resulting polyline inherits the properties of the first object that you selected.
If two lines meet a polyline in a Y shape, AutoCAD selects one of the lines
and joins it to the polyline. Joining also causes an implicit decurve, with
AutoCAD discarding the spline information of the original polyline and any
polylines being joined to it. Once the joining is completed, you can fit a new
spline to the resulting polyline.
Additional Editing Options for Polylines
In addition to the general editing operations available for most objects, there
are additional options available for editing and joining polylines with
PEDIT.
Close. Creates the closing segment of the polyline, connecting the last
segment with the first. AutoCAD considers the polyline open unless you
close it using the Close option.
Join. Adds lines, arcs, or polylines to the end of an open polyline and
removes the curve fitting from a curve-fit polyline. For an object to join
the polyline, their endpoints must touch.
Width. Specifies a new uniform width for the entire polyline. Use the
Width option of the Edit Vertex option to change the starting and ending
widths of segments.
Edit Vertex. Marks the first vertex of the polyline by drawing an X on the
screen. If you have specified a tangent direction for this vertex, an arrow
is also drawn in that direction.
