Path length increases when list is shifted

Hi all,

I noticed than when the 'shift list' function is used, the path length increases which breaks my geometry.

What is the logic behind this? Would it be possible for me to shift the list without increasing the path length? (i.e 1,2,3,4,5, -> 2,3,4,5,1) I tried searching for an answer here but couldn't find anything.

Thank you!

That's just what Grasshopper does. I am not entirely sure why it does it, but most operations increase the path depth by 1 digit. You can simply use Trim Tree to reduce it by 1 again or use simplify on both inputs of the geometry operation you are doing. Hope that helps.

"Trim Tree" worked great. By trial and error I also found that "Shift Paths" does it too. Thanks!

The tree has to become more complex, because you could choose to shift your tree using more than one offset. In that case, you'd end up with multiple output lists for each input list, and this added complexity manifests itself as a deeper tree structure.

I agree that this almost never happens with Shift List. I agree it is too cumbersome to 'undo' this sort of complexification. But those are things that won't be changed any more for Grasshopper 1.
