When you use transfinite for meshing a line, the characteristic length 
is ignored.
It will be taken into account for the surrounding elements of the geometry.
For instance:
lc =  0.1 ;
Point(1) = {0,0,0, lc};
Point(2) = {0,1,0,lc};
Line(1) = {1,2} ;
Transfinite Line(1) = 20 ;

The line is divided in 20 elements and not in 10 as it would be the case 
with the lc.

Using the extrude command.
See the attached example.
