Multi-pick
This method vectorizes a raster line that you define by clicking two or more
points. The multi-pick method provides you with more control over the
vectorizing process. It is useful for creating vector polylines, rectangles, circles,
and arcs.

After you select a raster line to vectorize, the AutoCAD command line displays
several editing options that vary according to the line type. In general, you
can select another entity to vectorize using the one-pick method, or you can
edit the vector line by entering numeric attributes or picking additional points.

Vectorizing Raster Lines and Polylines
The Polyline tool converts raster lines to vector lines or polylines.
ProdNameShort creates an AutoCAD entity with the same position and
dimensions as a raster line you select. Once ProdNameShort has vectorized a
line, you can verify its geometry (including angle and length), switch the start
point and endpoint, and trim or extend the line. Depending on the settings
you specified on the
dimensions as a raster line you select. Once ProdNameShort has vectorized a
line, you can verify its geometry (including angle and length), switch the start
point and endpoint, and trim or extend the line. Depending on the settings
you specified on the
(page 362) tab of the Raster Design Options
dialog box, the Polyline tool can remove the underlying raster when you exit
the command, force the vector polylines to conform to current drafting
settings, or assign layers to the vectors based on the width of the underlying
raster lines.

The default, or one-pick method, vectorizes a bitonal raster line with a
single click. The endpoint nearest the point you select is considered the
start point (an arrow glyph points away from the start-point). Depending
on which AutoCAD drafting settings are active, SmartCorrect automatically
corrects the resulting polyline to conform to current drafting settings.
