Apr 24, 2012 - Autodesk releases a pretty important hot fix for AutoCAD Civil 3D 2013 Survey Figure properties
The Survey Hot Fix for AutoCAD CIvil 3D 2013 fixes the problem with vertex properties display issues in the initial release version of Civil 3D 2013.
If you don't apply this new hot fix, Survey Figure editing is basically impossible.
