Joining Polylines

Command: PEDIT

Using the Join option of the Edit Polyline tool you can add an arc, a line or a polyline entity to an existing open polyline, forming one continuous polyline entity.

To join an entity to a polyline, that entity must already share an endpoint with an end vertex of the selected polyline.

When you join an entity to a polyline, the width of the new polyline segment depends on the width of the original polyline and the type of entity you are joining to it:

A line or an arc inherits the width from the polyline segment to which it is joined.
A polyline joined to a tapered polyline retains its own width values.
A polyline joined to a uniform-width polyline inherits the width from the polyline to which it is joined.
