I am working on converting some 2D features to 3D. I have successfully converted all of the point data to 3D by creating a new 3D geodatabase and feature set that includes Z-values and then using the "Convert to 3D by attribute" tool and using the integer elevation information to convert to true Z-value elevation. I have a network of polylines that are connected to these points in a 2D environment and i need to extract the elevations from each endpoint to give them the correct start and end elevation. So my question is:

Is there any way to extract the point elevation for use of polyline elevation other than manually creating two new attribute fields in the polyline attribute table for the elevation of the two points and then going line to line to look at each start and end point elevation?

Why not use the Add Surface Information tool in the 3D Analyst toolbox?
