Space frame grasshopper

failed (27.2 KB)
Having the above image as a reference image for creating a space frame structure in grasshopper. But failed in flip matrix component stage. So anyone kindly help me in this issue. I attached the failed file of mine for further reference. Thanks in advance

I usually don’t recommend that someone who are trying to learn GH as a newbie should refer to the tutorials with old GH versions. (20.0 KB)
