I'm trying to create a spiral polyline tower

[YANG_JEA_HYUN]

I would like to make that offset curve into a polyline connected only at each layer, but it is difficult. Is there anyone who can help?

This is the process I have followed so far.

Does this help?

In my GH file I internalize lots of values: your geometry, the Twist axis values, and the Pipe radius. You can connect sliders for these if you want to change them.

Hello
not sure of what you want, but if you want flat spiral, I think the most simple is to use a spiral formula as you seem to work with circles.
But if you want more general polyline spiral from closed curve you can look at

Spiral effect from a polygon

Hello, I’m would like to create an spiral effect from any polygon in grasshopper, but I have no idea where to start with it. It has to be something like the following image.Can anybody point me in the right direction… video, tutorial, script, etc. [spiral] Thanks in advance!

Creating 2D spirals from closed curves?

Following this discussion I wanted to give a try to a method to spiralize a convex polygon, I already did this some time ago on this discussion The algorithm use Clipper for the offset, the departure of the spiral depends on a point There is 2 types of spiral, the stepped one [image] [image] [image] [image]

also you can search by yourself with Google using these keyword and this syntax

I also have some tools in Nautilus plugin
