Need help for creating multiple interpolate curves at the same time

Hi ! I’m quite new to GH and my methods are still a bit messy.
I’m progressively getting to what I want in this model but I can’t find a way to do what I need :

(In the red group at the bottom of the workspace)

I have 3 lists of points (with 9 items inside each) and I want to create interpolate curves. Each curve get trough 3 points that have the same index number in each list.
I achieved to get one at a time with the List Item and a slider. If we move the slider we see that we’re getting the right curve at each index number (curves 2 or 5 as seen in the attachment).

My question is : How do you manage to get all the curves at the same time (as an output) ?

I guess it’s something about data matching by lists management but I’m not really a specialist yet :sweat_smile:

Thank you in advance for your tips !

In that case Entwine+Flip Matrixusually works most cases…

Wonderful thank you ! I knew it could be solved in a pretty simple way but I didn’t think to use these components :slight_smile:

For my acknowledgement, could you explain me quickly the logic behind the use of Entwine and then Flip Matrix in this case (in a data matching point of view) ?

Since I’m here I take the opportunity to ask a further question :sweat_smile:

The reason to create these interpolate curves is to get a surface (or SubD) between them (in the interior of the “tacos” (don’t know how to describe this form :sweat_smile: )).

I tried Sweep2rails (with the perpendicular edges of the slabs as rails and my interpolate curves as section), but the result is not what was expected haha.

Ideally this surface must be end on both sides with the point resulting of the middle of the “X” shape.

I don’t know if it’s explicit enough to expose the problem, don’t hesitate to ask for more if needed !

Thank you in advance

I’m getting there… I now just need to extend my loft at both ends toward the points (selected in green).

Any idea how I could manage to do that ?

Try inputting No. 2 to the “By Point?” input…

(I forgot to reply directly to your answer, sorry @HS_Kim → see above )

Awesome ! You’re the man, thank you @HS_Kim :slight_smile:
