What commands to make a set of shock absorbers 3D ?

I'd like to make a set of 3d shock absorbers with a spring using the classic Zmodeler 1 or 2, but I don't find suitable information to create the spring.
Anyone know the commands to use with Zmodeler ? thank you in advance.

In zmodeler2 you need 2 spilnes, one to define the helix shape and another one to define the round cross-section shape.

1. Create-Spline-Helix. To define how many rotations of the spring you want.

2. Create-Spline-Circle. To define the spring cross-section.

3. Create-Surface-Loft.

4. Click on the part that you made in 2.

5 Click on the part that you made in 1.

That should create the spring, if you use the correct views. It difficult to explain.

there's some help here on splines and surfaces.

Thank you very much master David
