Series of Element

Series of elements in x and y direction

Do you have any examples to show what you want to achieve?

And what are the driving factors for these trusses? What are the inputs?

For the next post, please do follow these guidelines, will help in getting to the solution much faster

I don’t think I still understand what it is that you’re trying to achieve.

Something like this?

By the way, are the two nodes connected to each other (between the two primary trusses)?


But I would suggest that you have a look at data structures in grasshopper and how you can simplify your definition further. It would be more helpful for you to use later. Your definition can also be simplified by a lot, so you can modify it later and extract useful data-points

You can have a look at the many tutorials on this forum and the old grasshopper forum
