Any ideas to lift it in 3d?
Thank you.

Hello carlosban71, yes you can do this in 3D.

First you draw an HELIX and then you SWEEP a circle representing the diameter of the coil spring ( diameter 22 ).
Do it longuer than the total length so that you can SUBTRACT the flat extremities.
The difficulty here is to modelize the extremities that are with a path of 22 instead of 34 at each end.
There is the possibility to modelize individually the top, middle and low parts of the coil ( next to come the explanations ).

P.S. If you open my file 3D solids 01.dwg available in the CAD/BIM Blocks library you will find the explanations for HELIX and SWEEP in the line : 3-SOLIDS CREATION 2 on page 1

Trying to line up the spring below as you tell me and not execute the sweep,

It's okay ? philippe JOSEPH

OK carlosban71, it looks good but why height 22.1 instead of the initial 22 and you could have placed the little diameter 22 at a better rotated place at the end of the spiral, vertical and not horizontal in the 'never known' case something could baddly happen with the sweep.
When drawing an helix you can always modify it whith the properties pannel ( Ctrl + 1 ).
I hope that you keep every step of your objects so that you can modify everything easily.
Remember that your helix will disapear when you do the sweep.
On the other hand the last image shows a good result and now you have to do all the other steps to get your final and complete coil spring.

OK carlosban71 do you mean that the sweep is not achived with height 22 but only if you do it with 22.1 ?

That's right, great teacher. Or is there some other command or some artifice or trick.
