Issue:
Users are experiencing major performance degradation throughout our organization. This is occurring in AutoCAD and Civil 3D. Files take 2-5 minutes to open, some longer depending on complexity. Plotting is slow, even the Purge command is impacted, taking up to a minute for the dialog to open, and sometimes an hour for the purge itself to complete. Audit and full Purge does nothing.Causes:
Known issue.Solution:
Note: Close Civil 3D and any other AutoCAD based application before installing updating files. You will need local administrator rights to apply the update.Important Notes: The update needs to be implemented on every user’s machine. The performance problem will return if an unpatched version of Civil 3D is used to open a file. The performance problem is fixed at the time a file is saved in the updated version of Civil 3D. The first time a user opens a file the update will not be evident. Performance will greatly improve after the first save. External references will need to be resaved to see the benefit of the update.
