You are correct...the 6 mm diameter spring causes a failure due to the parameters you have at the bottom of the path.
You can depending on your design intent:
1) Keep the path as is and reduce the diameter of the wire, In Figure 1, I reduced the diameter from 6 mm to 3 mm.
2) Keep the diameter the same and increase the pitch for Rev 0. In Figure 2, I increased the pitch from 6 mm to 9 mm.
Thank you for your reply Surendra.
The thing is, the spring is supposed to be 6mm thick. I'm going to try to design it by increasing the first and second pitch.
Could I kindly ask you for the .sldprt of the second spring anyway? In case I won't succeed on my own.
Thank you again for the tips
I tried to design a spring as well shortly after I started using SW. I decided it is fairly tricky. I found a macro from 3D Content Central that SW will run, and will design about any spring you want. The only thing is the taper does not seem to work.
Just save the macro to your computer, then in SW, go to <Tools<Macro<Run< and select the macro.
Hope this helps.

The problem is that SolidWorks can't handle non-manifold bodies, which is what you get when two of the coils just touch at the tangency point. One workaround is to very slightly change the pitch on the closed coils so that they aren't quite closed. With a 6 mm wire diameter you might try a pitch of 6.01 mm.
