Create surface between polylines or points

Dear all,

I’m just a beginner when it comes to grasshopper and I’m hoping you guys can help me out. I’ve created a 3D structure of polylines and points, where in between I want to add a surface. Does anybody knows a suitable solution?


What I have is a curve divided into 2 lines next to each other. And betwoon those lines I would like to create a surface. (2.2 KB)
