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.
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. Widths greater than zero produce wide lines, which are filled if Fill
mode is on and outlined if Fill mode is off.
Intersections of adjacent wide segments are usually beveled. However,
nontangent arc segments, acute angles, or segments that use a dash-dot
linetype are not beveled.
