Calling ArcHydro Tools

[MarkBoucher]

The code below is a combination of a Model Builder Export and my attempt to revise it. I've done rudimetary python programing, but not much arcpy until now. Any help you toss my way would be helpful...

The aim is to extract part of a DEM by mask a then call ArcHydro tools to do in arcpy what seems to crash in Model Builder. Code below extracts the DEM (rawdem) and adds it to the mxd. I'm happy to get this far.

The image at the bottom shows the Toolbox "tree".

The code fails to complete DEM Reconditioning. My gut tells me I just don't understand how to use the Import command, etc.

I get the following messages:
