Thanks Michael, its works well on z axis :)

PS: Wish on v2, its works well on any direction ;)

added to the whish list :)

Thanks PILOU! :)

Agreed, having a dependencies on positioning kills a creative session - especially when you don't know (or forget) that a tool has a dependency for this or that...

Maybe when you choose "flat", I can default to the world z axis direction, but show a button underneath it that says "Set flat dir", and if you push it let you pick 2 points to define the direction.

Why not automatic get helix both end points?

Hi Johny - that would be difficult because the default isn't "flat" mode, it is the freeform twist mode which does not need any direction information.

So that would feel a little odd if I forced you to pick 2 points every time you did sweep, but then did not use that information by default.

- Michael

Ah, I think you're right Michael ;)
Sorry, I forgot that 3dm file format not save start and end point of created helix information.

And I agree with a button option for select start and end point of direction if we select Flat mode.
