Serivice Pack 3 for Autodesk Civil 3D 2007 is now available for download. You will absolutely want to install it. With 100's of combined fixes (it also includes Civil 3D SP1A & SP2, Map SP1, SP2, & SP3, Acad SP1), and some excellent performance enhancements. This Service Pack is a must have.
If you are using Vault, the Autodesk Data Management Server 5 Service Pack 1 must be installed prior to installing C3D Service Pack 3.
Which reminds me to mention, read the download page and the readme. Many people ignore these items and then complain when a documented situation occurs to them. These items are not lengthy and can save a lot of time and heartache if someone has a documented special condition. Trust me it is well worth your time to go through these items.
OK, mine is updated.
