When a schematic database has been set up, any number of Schematic Group elements (SCGROU) can be created to form the primary hierarchy in the database. This can be considered similar to a folder structure in the file system. Schematic groups can be used to hold schematic elements, such as diagrams, stencils, templates, equipment, pipelines, cables and HVACLines. Schematic groups can also be nested in an arbitrary number of levels (having groups within groups). To create Schematic Groups, right click in the Schematic Explorer, or use the command line. It is also possible to import a standard Group structure into the database from a spreadsheet using the Spreadsheet Import function (please refer to Import in Chapter Working with Diagrams).
