Creating topography surface to export .STL file from XYZ .csv?

Hello All,

I am very new to Grasshopper and have traditionally used QGIS for creating topography but am trying to do it in Rhino.  I have a list of xyz points in a .csv attached.  I would like to interpolate a smooth surface based on these points.  Any suggestions are greatly appreciated.  I have tried the Delaunay Mesh but now need to smooth it and create a file in Rhino that can be exported as a .stl.

Thank you,

Anya

    Looks more like a cloud of points than a surface?  Are X, Y and Z mixed up?  (not that that would help)

      I'm not a "mesh guy", just hacking here...  Trying to trim out the extraneous faces/edges.  Just as I was about to post this, I realized that my filtering effort would be more effective and stable (not influenced by height scaling) if I project the mesh face boundaries to a plane before measuring them.  I'll try that next.

      This one was "done" so I'll post it anyway.
