System Variables
CIRCLERAD
Sets the default circle radius.
WHIPARC
Controls whether the display of circles and arcs is smooth.
Draw Polyline Arcs
A polyline is a connected sequence of line segments created as a single object.
You can create straight line segments, arc segments, or a combination of the
two.
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.
