The content of this book is an information model for technical drawings, the so-called "Drafting Model". Within the Drafting Model the annotation representations are described on the one hand informally and on the other hand formally using a high level language for information modeling, EXPRESS.

In this ESPRIT research report of a group of engineers in the CAD*I project the possibility of using a database management system (DBMS) for computer aided design (CAD) purposes is analyzed and conditions are derived that enable CAD systems to manage CAD models containing increasing amounts of data and more and more intelligent relations.
