Change the shape and
display of polyline objects with polyline editing options. You can
also join separate polylines.
example, modify polylines in several ways using PEDIT, the Properties palette,
- Move, add, or delete individual vertices
- Set a uniform width for the entire polyline
or control the width of each segment
- Create an approximation of a spline called
- Display noncontinuous linetypes with
or without a dash before and after each vertex
- Change the orientation of text in a polyline’s
linetype by reversing its direction
Modify Polylines with Multi-Functional
grips are multi-functional, providing context-sensitive options
for reshaping the polyline. Polyline segments have additional multi-functional grips
displayed at their midpoints. Control the display of these grips
with the GRIPS system variable.
grips also support the standard Grip modes (Stretch, Move, Rotate,
Scale, and Mirror). For information on working with multi-functional
grips, see Modify Objects with Multi-Functional Grips
grip-editing options that are available for polylines depend on
- The grip’s location (vertex or midpoint)
- The segment type (line or arc)
- The type of Polyline (standard, curve-fit,

Modify a Segment Within
select individual segments (or subobjects)
of a polyline, press Ctrl while clicking the segments. Use Grip
modes and multi-functional grip-editing options to modify the polyline
segments. The GRIPSUBOBJMODE system variable
controls whether grips are automatically made hot when subobjects are
You can modify the width
of individual segments with the Properties palette. Changing any
other property for a polyline segment affects the entire polyline.
Modify Polylines with Coincident
Coincident grips are grips that are shared between
multiple objects. When polyline objects sharing the same grip are
selected together, multi-functional grip-editing options are not
supported for the coincident grip. However, you can still edit the
coincident grip using the standard Grip modes (Stretch, Move, Rotate,
Scale, and Mirror).
grip-editing options for coincident grips are supported when only
one of the polyline objects is selected.
Join Polyline Segments
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.
return to their original shape when joined. Polylines cannot be
joined into a Y shape.
the properties of several objects being joined into a polyline differ,
the resulting polyline inherits the properties of the first object
that you selected.
