How to draw helix in CST 2006

How to draw a linear helix with no change in radius in CST 2006.
In CST 06 coils construction,linear circular helix option is not there.

Not sure if CST 2006 has this feature, but I recently created a helix in CST 2013 using the analytical curve function.
Use x: R*cos(t) y: R*sin(t) z: t
R is your radius and set t go from 0 to the length of your helix.
If you want the helix you have a solid form, create a circle at the base of the helix curve. Then use the sweep curve function to generate a solid form helix.
Hope this helps!
