To convert a raster line to a vector line or polyline
For straight lines, click Image menu  ➤  Vectorization Tools  ➤  Line. Or
for polylines, Click Image  ➤  Vectorization Tools  ➤  Polyline..
The following prompt appears:
Specify one-pick point or [2P]:
NOTE When you use the one-pick method to select the raster entity,
ProdNameShort corrects the point you picked according to the current
drafting settings or rounding values. For more information, see 
 (page 205).
Do one of the following:
Select a raster line by clicking near the beginning of the line. The
endpoint nearest the point you select is considered the start point.

the point.
Select another raster line using the one-pick method, or do one of the

Enter l (Length) to verify the length of the vector line segment you
just created. See 
 (page 210).
Enter u (Undo) to remove the last vector line segment you created.
