As a way to understand what CODE A is doing I’ve tried to break it apart and replicate it in CODE B.
20 surfaces go in, removing any below the Z axis, leaving 10. However, my CODE B continues to pass through all 20 surfaces. “” in the original code seems to be key to the issue but after trying many configurations I can’t replicate the output of CODE A. I’ve read, in researching the problem, the square brackets are addressing which item to process or pass through etc. but I can’t fathom where to put it.
Any hints would be appricated.
