Selective loft

Hi guys!

My problem may appear very easy to solve, but i still didn't find a way:

I've a branch of flatten data like that:

{0}

0 Poly Curve

1 Poly Curve

2 Poly Curve

3 Poly Curve

4 Poly Curve

5 Poly Curve

6 Poly Curve

7 Poly Curve ... etc

I need to loft half of them as a pattern like 2 by 2... ex:

0 with 1 ---> loft

1 with 2 ---> no loft

2 with 3 ---> loft

3 with 4 ---> loft

4 w.... etc.

In my case (as you can see in the screenshot) i've two list in whic i've to apply this process.

I can't use list items because the numbers of items may change, and if i get a grafted list of items i can't loft the curves, but if i get the flattened pattern of data the loft component loft everything without considering the sequence.

I guess i've been clear to explain my data structure problem!

Pls! I'm waiting for some help!!! Thx a lot in advance,

Marco

List items should work. Just plug in a series component to select just the ones you want. E.g. Start number 0, step size 2, number of values in the series = the list length of the list of curves.

So two series, two list items, two grafts and a loft.

Thx Brian, but mmmh... no I've tried in that way but doesn't work, because what i need is to create a sort of group of items each couple {0} 0;1 {1} 2;3 {3} 4;5 etc... each 2 list items have to became a new branch... how can i do that? :(

What Brian is suggesting will work, you simply have to graft the output of the series components.

Oh and don't worry about the red loft... there are some nulls in there because I set the series to go way higher than necessary.

Uh yes! It works perfectly, sorry but I didn't get what Brian suggested to me exactly! Sorry, i've missed the second part with the injection of the new merged index into another item list component! So thank you Brain and thank you Andrew for your help! :)
