Civil 3D Update 2 pulled from Autodesk website

Autodesk recently released Update 2 to address several issues with Civil 3D, but has pulled that update due to an issue with very large surface models -- those containing more than two million points.

If you work with very large surface models, do not install Update 2, or uninstall it if it has already been applied. Autodesk is working on a solution for this issue and will post a new Update 2 soon.
