Construct mesh from a curve and a point

Hi everyone,

I am a newcomer, really fresh to Rhino and GH, but as an engineer/design student, I try to figure my way around things here. Sorry if my question is way too simple :/

I basically construct a list of point from a file, make a nurbs out of it and then simplified it.

This is motion tracking data, so it's a trail basically. (points are discontinuous and then linked).

I manually found the "centroid" of that curve, and constructed it.

I now want to make a surface/mesh (anything i could work on to make it 3d printable) between this rather complex curve and the point. Like lines from that point to every points of the curve.

I tried surfacegrid, delaunay, triangular, but it seems i cannot input the curve and point separately to make it work.

I dont think the complex geometry of the curve should be a real problem, would it?

Thanks for your help guys
