Is there a way to create alternating curves (fish scale pattern)on Dynamo? I’m trying to recreate this image for my assignment just need some guidance on how make alternating rows?

Hello @CJAYY and welcome to the forum, please show us how you have tried so far in dynamo and we can try help from there…but try pattern toolkit maybe or just ootb nodes

Not as slick as @sovitek. Modulo is you friend here

x=((0..cols)%2)*r..(cols*r+((0..cols)%2)*r)..r*2;
y=0..(row-1)*r..#row;

Thanks again @sovitek . I cannot seem to find the nodes for “Curves shatter” and “polycurve closed loops from curves” were this from an extension? is there another option to do this without the extension? Thanks so much!

Hey…curves shatter and polycurve… is from ampersand package, a great package and almost created with ootb nodes so basickly very simple… guess thats why the package have survive in so many years, no matter api change etc…so yes can be done with ootb as well…but will probably be a long one :wink:

here is eks curve shatter with ootb and its actuelly just split by point OOTB
