f the angles of that meet at a vertex are anything but 360 degrees that means that the faces around that vertex cannot be unfolded flat without introducing a seam. I wanted to avoid adding extra seams so I calculated the location along a surface normal that would allow the face angle sums at the centroid of each plate to equal 360. See this diagram on my website: http://matsysdesign.com/wp-content/uploads/2012/04/Chrysalis_III_Plate_Diagrams-01.png

ortional, where 360 means 360 degrees. By doing this, all the loops will have the same width.
The diameter is given by the distance of the center and the first point of the curve. I started the helix from outside, not from inside.
Anyway, tks a lot for your help. I really need to go deeper on curves. I need to understand how they really work, and the differences between them all.
I am really new in Grasshopper, and this is the only way I could find the solution. I am pretty sure there is something better.…
Hi Chris,
first off, angles in Grasshopper are always specified in Radians, so you'll need to lose the 360 factors in your equation. See attached.
