Draw Linear Objects | 263
Multisegmented lines provide editing capabilities unavailable for single
lines. For example, you can adjust their width and curvature. After you've
created a polyline, you can edit it with
PEDIT or use EXPLODE to convert it to
individual line and arc segments. You can
■ Convert a spline-fit polyline into a true spline with SPLINE
■ Use closed polylines to create a polygon
■ Create a polyline from the boundaries of overlapping objects
Create Arc Polylines
When you draw arc segments in a polyline, the first point of the arc is the
endpoint of the previous segment. You can specify the angle, center point,
direction, or radius of the arc. You can also complete the arc by specifying a
second point and an endpoint.
Create Closed Polylines
You can draw a closed polyline to create a polygon. To close a polyline,
specify the starting point of the last side of the object, enter c (Close), and
press
ENTER.
Create Wide Polylines
You can draw polylines of various widths by using the Width and Halfwidth
options. You can set the width of individual segments and make them taper
gradually from one width to another. These options become available after
you specify a starting point for the polyline.
The Width and Halfwidth options set the width of the next polyline
segments you draw. Zero (0) width produces a thin line. Widths greater than
zero produce wide lines, which are filled if Fill mode is on and outlined if Fill
mode is off. The Halfwidth option sets width by specifying the distance from
the center of the wide polyline to an outside edge.
