I have lines from AutoCAD of bathymetry data, imported into ArcMap.  It is spatially referenced, however the contour lines do not have Z-values associated with them.  I have a paper copy of the map, and would like to assign the values to the lines manually.  However, simply creating a field in the attribute table isn't enough...I would like Arc to recognise those values as the actual 3D elevation.  How can I do this?

Once the data is entered as attributes, the 3D analyst 'convert features to 3D' can be used with the Z field as the input.

Thanks for your reply, unfortunately 3D analyst for 9.1 doesn't have that tool.  Any other suggestions for 9.1 users?
