Trace Line
Trace Line will convert a line in an image into a single CAD
polyline. If an image is "current" through the Set Raster Image command, simply run
Trace Line and click on a
line in the image. In the command line, you will see the
Line Length, Angle, and Thickness reported for the new
polyline. The command line will also prompt you to change the
Angle, Length or Reverse the direction the new polyline
if desired. To accept the new line press Enter. To cancel, type C
or press Esc.
Different images have different resolutions or quality to them. To
account for this, you can adjust the parameters that the program
tries to recognizes linework in an image with Edit Raster Options. Here is also where
the default Layer for the
new polyline is determined.

Line Length=780.00 Angle=269°32'47" Thickness=5
Enter to accept line or [Angle/Reverse/Length/Cancel]: Type
in the first letter in a word to adjust that element of the new
polyline. For example, typing in "A" would allow you to
adjust the Angle.
