Rajesh,

What are you trying to do exactly? Use Helical Sweep to create threads, springs, helical surfaces; use From Equation Curves to create a helical curve.

I believe you can find an example in the Help files, but here you go:

Create a **Curve,** **By Equation**, select a Coordinate System with Z on the axis of the helix, and choose the **Cylindrical** option.

Now enter the following equations:

**r=2**

**theta=t*360*8**

**z=t*5**

These are examples of true parametric equations. In this case t is the governing parameter, and by definition it is the independent variable which goes from 0 to 1 to generate the dependent values. Thus, the 8 gives you 8 full turns, and the 5 gives you a z-height of 5, radius of 2. This can also be done with the Cartesian option using sin and cos, but Cylindrical is the easiest.
