Due to the complexity of most architectural projects, and to enable you to retain the desired numbering sequence even after Layouts are added and removed from the Layout Book, most users will prefer to use an automated method which assigns an ID to each layout. The smart ID assignment system automatically adjusts itself whenever the Layout Book is changed (for example by the addition of new Layouts, changes in the Layout order or in the document structure).
“Layout ID” is available as an Autotext entry, so if you add the Layout ID Autotext to the Master Layout’s Title block, then each Layout will be numbered with this ID.
Go to Document > Layout Book > Book Settings. Choose your preferred method for assigning Layout IDs:
Both the prefix and the style (1-2-3, A-B-C, etc.) of the layout/subset ID can be customized. The resulting layout ID is usually a letter-number combination, such as A-03/a.
Note: At any level of ID assignment (Book Settings, Layout Settings or Subset Settings), you can choose a style of “No ID”. As part of the automated ID system, every sub-item in that group (e.g. every layout in that subset) will be assigned an “empty” ID, which is like no ID at all.
