The most efficient way of creating a title block is as a separate DWG file, drawn at its normal plotted size (for example, 36″ x 24″ for an architectural D-size title block, or 841mm x 594mm for an ISO A1-size version). You then insert (see ssss1) or xref (see ssss1) the title block drawing into each drawing sheet.

When you start in either the Drafting & Annotation workspace (as I do throughout this book) or the old AutoCAD Classic workspace, AutoCAD creates a new, blank drawing configured for 2D drafting. Depending on where you live (your country, not your street address!) and the dominant system of measure used there, AutoCAD will base this new drawing on one of two default drawing templates:

 acad.dwt for the imperial system of measure, as used in the United States

 acadiso.dwt for the metric system, used throughout most of the rest of the galaxy

acadlt.dwtacadltiso.dwt

You may be familiar with Microsoft Word or Excel template files, and AutoCAD drawing templates work pretty much the same way because Autodesk stole the idea from them, encouraged, of course, by Microsoft, although one could argue that it was the other way around.
