Tangent Curve and Sweep 2 surface

Hey guys,

I was fighting with this one for a couple of days now.
I have a simple spiral surface and I want to extend it with another one.
The only thing the top spiral has to shift its centre of rotation.
I crated a series of control sections for it. And it works.

I have two problems with it though:

  1. Top curves are not tangent to curves below
  2. The surface I get is deformed in a strange way. It’s iso curves are not parallel to xy plane

Any I idea how to make it nice ?

Thank you

Ok I tried curve interpolate with start and end tangents . it looks better, but I still not getting smooth sweep ?

Still can’t make it to look correct :frowning:
