data tree manipulation in grasshopper 0.5

Hi all. So I am working in 0.5 (cannot update, using a locked public computer) and I am having some trouble.

As a way of explaining my problem, I just made three sets of points
and tried to connect using a pline, but instead of giving me 11
triangles, it goes from each point sequentially, giving me one line
that traces through all the points.

How can I make a new set combining for example all the 1st points in
each branch, then all the 2nd points in each branch and so on, in
order to link with a polyline?

Is that possible to do in grasshopper? Any help would be greatly appreciated.

You really, really need Grasshopper 0.6 for this. The whole point of Data Trees is to make stuff like this possible.

I am now working in the most recent version and I still have a similar question. How would you do this in 0.6?

I have looked through the forum but I cannot seem to piece together the steps to make it work. Any help would be appreciated.

Before answering this can you clarify which version you have. Latest version is 0.8.00010, 0.6.xxxx was the first introduction to data trees so whilst its capable of performing as you wish there have been far more momentous improvements since then.

apologies. i am still using 0.6.0059. i will update to 0.8 and see if I can figure it out from there.

if i read the forum right though, would it be something like using the path mapper in three separate instances to isolate the point on each line and the connecting via a polyline?

Probably not. I would say the easiest way is to use the Flip Matrix component if the path structure is right it will change columns to rows and vice versa.
