you know could “internalize” curve inside Grasshopper script, so no need of the rhino file. Right click on curve component …
you also could upload image with this button
For your problem the most simple, not fastest, is to use isosurface, here from Millepede

Using V7 it is also possible to remesh it with quad and smooth it very well …
Many many ways, variations …
