Hello guys, I split the strips with some vertical columns but when I want to retrieve those contained in group 0, for example, it mixes some of them with others. I tried to sort them but the result is the same; I guess is a data tree branches adjustment.
Thanks!
there are really weird splits 
also, some polysurfaces are open others are closed, which makes complicated to check stuff like Point in Brep
I think the best way would be to share the part of the definition prior to the initial strips and columns, and work on those… probably trimming strips with columns before cutting the strips into this triangular shape?
This was ridiculously difficult for what appeared to be simple 
Due in part to the poorly created columns, as @inno said. I rebuilt them. (yellow group)
Alternate method using bounding boxes and grouping by domains. A bit long winded, but nothing too complex. Largest group is for creating and placing labels.

As already mentioned by @inno and @Joseph_Oster, this could be simplified by using alternate methods to create your geometry.

Thank you @kev.r for your support as well !!! I really appreciate it:) I spent too much time trying to solve this problem
