Hi,

I think the easiest way to convert metaball data, which in this case is your points is to use a marching cube algorithm(Cocoon). However this will produce a mesh, is that ok? if you want nurbs I am not quite sure how, maybe someone has a better idea.

Thank you  

Let me know if it does what you want, or if you need some further help.

I am sorry but i do need help ,i am a beginner in gh so would you please tell me how can i complete the nodes . What i want to do is making the mateaballs curves into mesh or nurbs and then subtract the model from a cube , so if you please ; would you  complete the nodes.. thanks a lot

You can download cocoon from here:  http://www.bespokegeometry.com/2015/07/22/cocoon/

And then follow this screenshot to recreate it yourself, given that it is what you wanted :) :

I am very thankful for your time and effort 

No problem, and good luck
