A common procedure within the Project Navigator is the need to change the name/numbering of the sheet file. In past releases of ADT (2004/5) we had the option of renumbering the sheet by simply selecting the sheet>>right click and choosing the rename and renumber option.
In 2005 the fields feature was introduced allowing you to populate your titleblock with the associated data, which allows for better coordination. Unfortunately when renaming the sheet title this did not rename the associated .dwg file and lead to some confusion.
In 2006 there are two new options when renaming which include Renaming the associated .dwg file to match the sheet title and prefixing the sheet number to the file name.
