Ta p e r

When you use the Width option, AutoCAD prompts for both a starting and

an ending width. By entering different values, you can taper the polyline.

The starting and ending points of wide polyline segments are in the center

of the line. Intersections of adjacent wide segments are usually beveled. How-

ever, AutoCAD does not bevel nontangent arc segments, acute angles, or

segments that use a dash-dot linetype.

Create Polylines from the Boundaries of Objects

You can create a polyline from the boundaries of overlapping objects that

form a closed area. A polyline created using the boundary method is a sepa-

rate object, distinct from the objects used to create it. You can edit it using

the same methods used to edit other polylines.

To expedite the boundary selection process in large or complex drawings,

you can specify a group of boundary candidates, called a boundary set. You

create this set by selecting the objects you want AutoCAD to examine as it

defines the boundary.
