I want to display DWG over AGS service in Explorer.
It seems there's no default option for this.
Is it possible at all?
If not, what tool except ArcGIS Desktop can make this?
it's not possible to add CAD data directly to ArcGIS Explorer Desktop. However if the CAD data is added to ArcMap and saved out as a layer file (ArcGIS layer) or layer package, ArcGIS Explorer Desktop will display it, when the Layer is added.
