If the polyline you select is a closed polyline, Open replaces the Close option
in the prompt. You can edit a 2D polyline if its normal is parallel to and in
the same direction as the Z axis of the current UCS.
Close
Creates the closing segment of the polyline, connecting the last segment with
the first. The polyline is considered open unless you close it using the Close
option.
Open
Removes the closing segment of the polyline. The polyline is considered closed
unless you open it using the Open 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 objects to join the polyline, their
endpoints must touch unless you use the Multiple option at the first PEDIT
prompt. In this case, you can join polylines that do not touch if the fuzz
distance is set to a value large enough to include the endpoints.
Jointype
Sets the method of joining selected polylines.
Extend Joins the selected polylines by extending or trimming the segments
to the nearest endpoints.
Add Joins the selected polylines by adding a straight segment between the
nearest endpoints.
Both Joins the selected polylines by extending or trimming if possible.
Otherwise joins the selected polylines by adding a straight segment between
the nearest endpoints.
Width
Specifies a new uniform width for the entire polyline.
You can use the Width option of the Edit Vertex option to change the starting
and ending widths of a segment.
