double principle

[Cla]

Good morning to all.. .

I'm doing a cochlea with double principle and same geometric characteristics of the two "eliche"... a say that develops for a step and a half, the other more or less for 0.5 steps, the problem is that I would like the most advanced point of the two spires to be on the same axial coordinate of the cochlea...how do I??? the problem I believe is in the understanding of the helical sweep command in which section,profile,pass,etc

I hope I've explained well...

the simplest and fastest way is to use special copy/paste of the first helix, then it emerges both "application transformations of movement/rotation" and "create copy according to the original quotas", and as transformation from a rotation of 180° through the axis of the tree.
method two, always with special copy/paste: instead of using the transformation, if you don't think this option will ask you for new references to recreate the copy of the feature; as references from the same ones used in the first helix, when it proposes the first orientation of the planes (the sketch side, green and red arrows), reverse the sense so that they are opposite, the second orientation (horizontal sketch) keep the same orientation.
