Anil,
You can try creating a curve by equation for coil.
Sample equation is:
/* Diameter internal
d = 100
/* Pitch
p = 50
/* Number of Revolutions
r = 10
/* Height - Should be 0 for plane
h = 0
x = ((d/2 + p * r * t) * cos ((r * t) * 360))
y = ((d / 2 + p * r * t) * sin ((r * t) * 360))
z = t * h
There is a very good document for the same at Equations for Curves (and more)
