Helix pattern with closer range of twist

[CinnamonMetal]

I've created a helix pattern in vex but, the problem is I need a close twist within a range of points, and the helix code pattern it creating a DNA strand type of helix, any suggestions ?

play with this one maybe :).

If you want to create a DNA strand, you can use two helices (with different offsets). You can transform these two curves to a guide path using a path deformer. After this you can create attributes for orientation / legth / positioning etc... . With these attributes you can copy/transform a geometry  (a box for example) to each of these position.

Here is a setup.

@Aizatulin Thanks this is close to the type of helix I wanted; there are alot of options,  did you create it ? 

[Aizatulin]

Yes,

you can use or modify it, if you want.

Here is another file with some optimizations. There are probably alot of other ways to do this (even much faster). You can randomize the input, to get different types of copies.

In the helix for example you can modify the radius along the ramp. If you want to use other components (like helix, path deformer etc...), this should work aswell.

There is alot of options but hopefully I can use what I need into my project, thanks
