Hello @inno ,
You’re absolutely right, next time I’ll cite/not delete the references! Thanks for the advice 
.
About the method used by Making bridges on self intersecting curve - #6 by seghierkhaled, I had already tried it, but for the goal I have, I think which I’m using ismore useful.
@laurent_delrieu , thanks for the tool to suppress intersections, but I specifically need those intersections.
My idea is to recreate the deposition of a filament as in the photo (not 3D printing):
The image is from matlab code that generates the coordinates for creating these filaments.
The exported matlab coordinates in GH:
The code works with ARC, and I want to try reproducing non-circular geometries in GH.
At the same intersection point, the filament could be deposited multiple times.
The deposition is without intersecting with previously printed filaments, and there is a little filament deformation (hence the use of that ‘ellipsoidal bridge’).
With matlab coordinates Fibras_random_busano(1).gh (47.2 KB):
I’m thinking of giving GH coordinates to know the order to print the filaments. Do you think it’s possible to achieve this triple-multi-overlap without using a Python script?
I’m also trying to use the Termite tool, but the technique reproduced there is the FDM, fused deposition modeling, and I can’t force (I believe…) the creation of that ellipsoidal bridge.
