algorithmic modeling for Rhino

Hi,

I've been struggling with a problem so I thought I would fire it at the community, I hope it isn't too difficult to workaround.

I've got point coordinates from a number of random curves, listed in branches. I want to re-order them so that the curves are listed in ascending order from their first x coordinate. So basically the curve starting from the furthest left will be at the top of this list. I've attached an image to demonstrate. 

Any help would be much appreciated.

please upload something to have as a base to help you with, it looks like these are coordinates so it is not like a simple list of values. Meaning that the first index in each list you want to compare has more one value.

cheers

Anyway

you can try the following

first you have to deconstruct the point into xyz coordinates (deconstruct point component) then you have to sort the 3 list with the x values. then you have to sort synchronously the branches according the sorting of the minimum x values in each branch.

and you re done

cheers

ps dont forget to right click the select branch component and select renumber

thanks!

Thanks a lot Alex and Torben. Exactly the solutions I was struggling to achieve.

I should have posted my definition, i'll make sure to next time i'm in a spot of bother.
