Draw Polylines
A polyline is a connected sequence of segments created as a single object. You
can create straight line segments, arc segments, or a combination of the two.
Polylines are ideal for applications including the following:
Contour lines for topographic, isobaric, and other scientific applications
Wiring diagrams and printed cicuit board layouts
Process and piping diagrams
Extrusion profiles and extrusion paths for 3D solid modeling
Polylines can be created with several commands including PLINE, RECTANG,
POLYGON, DONUT, BOUNDARY, and REVCLOUD. All of these commands
result in a LWPOLYLINE (lightweight polyline) object type.
With the 3DPOLY command, you can create non-planar polylines that result
in a POLYLINE object type. Fewer options are available with 3D polylines.
After you create a polyline, you can edit it using grips or PEDIT. You can use
EXPLODE to convert polylines to individual line and arc segments.
NOTE You can convert a spline-fit polyline created with PEDIT into a true spline
object with SPLINE.
