If there is already a projection defined, then reproject raster to a similar coordinate system of your data.  Hope this helps.

When I do this, I receive this error message: "one or more of the layers has an extent inconsistent with the associated spatial reference information." Do you have any idea why I might be seeing this, and if I can see it on the CAD side? Thanks! Using your method, I successfully exported a DEM from Civil 3D, and would like to import it into ArcGIS.

Is there a way to export to a DEM and maintain a reasonable accuracy in the elevations? I've tried fiddling with some of the parent drawing settings, but cannot seem to find anything that will allow me to transfer the data to DEM with anything but a "nice" round number. Thanks!
