Hi there,
I would like to create simple 2d-spirals. The center points I want to use from circles I have created before and the spiral should stay within the circle.
I’ve been trying this, but it didn’t work…
here’s also the file:
Spiral.gh (12.5 KB)
See attached
Spirals_OnCircles_V1.gh (117.1 KB)
Ok, I’m not quite sure whats going on in this code put it works hahah. Thanks you, MY LORD 
Nothing worth to bother you.
Get this as well:
Spirals_OnCircles_V1A.gh (120.4 KB)
Notify if you want far more interesting Spiral stuff. Like: (A Spherical option shown)
PS: SpiralTypes are many:
cool! thanks!!
Spirals I put in my Nautilus plugin
Hi again, so I’m having this “conceptual” problem here, where I have several lines as input, which all have this area where they are in closer proximity. Now I want to generate offset curves that kind of meander in between this lines:
Tween curve doesn’t work because of the exceptions when two lines are on the same side.
Any Suggestions to solve this geometrically with a grasshopper script?
This means C# (very easy in “most” of cases) or native stuff?
BTW: If C# what sort of animals are your curves? (planar or not, closed/open, self intersecting … blah, blah).
So this is all in 2D. The black inputs are simple lines and the red curves are planar open curves.
…and preferably I look for a solution working with the “native stuff” 
Like said by @PeterFotiadis there are many things that could lead to a difficult solution. C# Python seems better as they allow to treat more scenarios. By the way it is a nice problem.
Cross fingers for some other good Samaritan who likes that kind of thing. In fact I have a C# that does that … but I can barely remember where is.
Okay, I see your point, Pfotiado & Laurent. I understand a bit of Python, but C# I cannot read that good… and in the end I think I should at least understand the code.
At the moment for you problem it is not really a problem of Python or C# but an algorithm, strategy, object problem.
There are some simple cases but also some other more complex.
For example
generate lateral lines a distance D (simple with curve offset loose )
Generate some offset/pills at distance D*1.5 (I use Clipper that can offset a line)
Cut the lines with the pills.
Then blend the cutted lines.
But what to do here
For sure other strategies could be chosen. Height fields perhaps ?
