Go to Help > ArchiCAD Help, after your browser launches switch to the Search tab and search for "Master Layout" and then "Autotext" for information about these features. You can also go to File > New and open the ArchiCAD 12 Template to see how the layouts (sheets) and Master Layouts are set up as an example.
And again:You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
