Editing polylines with the PEDIT command

Because polylines can be quite complex, AutoCAD has a special command to edit them, PEDIT. To edit a polyline, choose Modify О Object О Polyline. AutoCAD responds with the Select polyline or [Multiple]: prompt. Select a polyline

and AutoCAD responds with the Enter an option [Close/Join/Width/Edit vertex/Fit/Spline/Decurve/Ltype gen/Undo]: prompt. The options are as follows:

   Close: Closes an open polyline. If necessary, it adds a segment to connect the endpoint to the start point. If the polyline is already closed, this prompt becomes Open. Open creates a break between the first and last segments of the polyline.

   Join: Joins touching lines, arcs, or other polylines to the polyline.

   Width: Enables you to specify one width for the entire polyline.
