Modify or Join Polylines

Additional editing operations are available for changing the shape and display of polyline objects. You can also join separate polylines.

You can modify polylines in several ways using PEDIT, the Properties palette, or grips including the following:

Join 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.

Spline-fit polylines return to their original shape when joined. Polylines cannot be joined into a Y shape.

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.

Modify a Segment Within a Polyline

You can modify a segment in a polyline using the MOVE, ROTATE, or SCALE commands. You select the single arc or line segment, also called a subobject, within a polyline by pressing Ctrl when you click it.

You can also use the Stretch, Move, Rotate, and Scale grip modes to modify the polyline segment. Properties of polyline segments such as color or linetype, cannot be modified individually, but you can use the Properties palette to modify the width of individual segments.
