So I am pretty new to Grasshopper, only been at it for a couple of months now, so please forgive my ignorance. I have been stuck on this problem for a couple of days now and just can’t seem to figure it out.

Basically what I am trying to do is recreate an expanding scissor truss structure based on a Chuck Hoberman idea

I have been able to create a singular arc, but am having difficulties now that I am trying to create a unit that I can be arrayed or used to generate a series at varying sizes and orientation.

I believe that the problem that I am experiencing is related to the way in which the data is grouped and matching up data after it has been put through certain components.

In particular there is a point at which the data stream goes from having 2 groups of 6 to just 12 groups.

I just don’t know how to solve this issue.
