Loft issue, data shuffling

Hello guys!

I’ve got an issue whlie tried to create a loft between two trees of rectangles.
For some reason data in those trees shuffles randomly and loft goes incorrect.
The problem solves when I’m using my algorythm for two same curves, but I need them to be different.

Thank you in advance! (16.2 KB)

You can’t maintain the order of planes if you use Merge in this case.
Try Shift Patternand Combine Data instead… (22.6 KB)

Thank you Kim for your answer!

You solved my problem.
I’m pretty new in working with data streams :slight_smile:
