3D HelicalCurve follow coil

[geert.van.pelt]

For a screw conveyor I am trying to work with different pitch. I managed this with coil featur. Now I try to do the same with the 3D helical curve, but here is a difference between some pieces. Can someone help me what I need to adjust to get this done?

Hi! I could be wrong but I believe there is indeed subtle difference between Helical Curve and the resultant edges created by Coil. The Helical Curve algorithm is newer and it is able to accommodate variable-radius and variable-pitch cases, while Coil cannot do the same.

Many thanks!

You're right, that's why I created multiple coils in a row with a different pitch
