We use custom projections in ArcGIS for AutoCAD within which feature service displayed perfectly prior to our upgrade from AGS 10.1 to 10.3. For instance, our users have working drawing in which they connect to AGS, add the feature service and sync lines to the db. For some reason, just since the upgrade, the feature service comes in shifted entirely. Like I said it worked perfectly in 10.1. Civil 3D 2011.
Any ideas?
