Hi, please check this example:

How can I, in a GetItemAtIndex sort of way, pick the second list from the first, resulting in:

Index [2] from list [0]

Index [0] from list [1]

Index [1] from list [2]

GetItemAtIndex doesn’t work, as it seems to discard the nested Index-list:

Thanks in advance. I’m using version 0.9.2 in Revit 2016 btw.

Hi Lennart ,

List combine does what you want :

Thanks, this works exactly as I wanted!

Haven’t used this node before.
