After a drawing has upgraded, it is possible to use the Define and Define Branch commands to re-create database data. Before the define operation can be successfully performed, base data such as the Schematic Groups, System Structure, Specification and Catalogue Items etc. will have to be created. Also relevant default settings will have to be set up properly, for instance Default Groups.

When the shapes have been defined, the Consistency Check function (please refer to Consistency Check in Chapter Working with Diagrams) can be used to check that the diagram is consistent with the database data.
