Insertion Item - use of Indices port

Dear Sirs

I have generated an Insertion Item as attached and a bit puzzled on what the “Indices” Port mean.
I know that the “Item” input port will generate an offset from the base, but what about the Indices Port?

I am aware that it is normally kept as zero and just wonder what is the logic if I change it to another digit , how would it affect the order of numbers in the “Partial Results” output?

Many thanks!!
Kind regards

As you can see in the attached screengrab, Insert Itemswill let you insert “0” into the index 3 and 5 of the existing list, and the resulting new list has two more items than previous list.

Thanks HS Kim

I am not getting the same result as you, have I missed something? Please see the attached!

Many thanks!

Thanks Kim, I understood what you meant when we shuffle the Indicies as per your screen cap.

Would that have an impact on the final result of my contours? I cannot see any impact on the contours distribution myself in the attached file when I shuffled the indicies of the Insert Items.

Please correct me if I am wrong,

Thanks so much!
Merry Xmas!!
