Thanks....v13 worked like a charm after I got my hands on it. I prefer interpolating surfaces in SMS than in ArcGIS b/c in my opinion, the results look better plus it is a lot quicker for me to generate and control how it is done in SMS

I'm in SMS 12.3 and was wondering if there was a way to convert a 2D mesh representing bathymetric surface elevations of a lake to a GeoTIF raster so that I can import it into ArcGIS for further analysis. Do I convert first to something else like a grid or scatter set? I created the mesh from first converting scatter points collected during a boat survey to the 2D mesh via linear interpolation. Thanks Rob
