Convert mesh to srf

How do I convert a mesh to a surface? I have tried deconstruct mesh and linking the vertices to the srf grid tool but I dont understand the u-value. Perhaps this is the wrong way to go about this conversion?

I am working with kangaroo. I am a grasshopper and kangaroo beginner.

Thank you in advance for the help!

If your mesh vertices are nicely ordered (as they are if it’s a simple quad grid generated in grasshopper), then you can use this approach. The U count of the surface needs to be the H count of the mesh plus one.

If your mesh comes from a different source, or isn’t a simple patch, it can get a little trickier. If it is multiple patches, you should be able to apply a similar technique to each 4 sided patch.
