I just reviewed an Autodesk document that reminders/warns users that after applying Service Pack 3 for Civil 3D 2007, four of the Templates (.dwts) that ship with the product will now contain 6 errors that will be found with an AUDIT command. The templates are:
_Autodesk Civil 3D (Imperial) NCS Classic
_Autodesk Civil 3D (Imperial) NCS Extended
_Autodesk Civil 3D (Metric) NCS Classic
_Autodesk Civil 3D (Metric) NCS Extended
This is a good time to point out that running the AUDIT command in Civil 3D drawings, or our custom templates, is ALWAYS a good idea. We should get into the habit of running this command often. Some companies have even automated the use of this command upon the opening of every file. Drawings with Gradings and Parcels are particularly sensitive to corruption and should be kept clean.
The AUDIT command is similar to visiting a doctor for a check-up. Preventative actions should contribute to the avoidance of Fatal Errors.
