Editing the Calculation Database

Choose the Edit Database command. The resulting dialog box contains the controls to create, customize, modify and delete the elements of the database(s) ARCHICAD uses to process your project information for reports.


The information elements are arranged in hierarchical order. You can view the contents of a database in the left-hand side of the dialog box.

The right-hand side of the dialog box changes according to the item selected on the left (see specific sections for details).

At the bottom of the dialog box, use the “Details of Database items on the same level” section to view the details of all the items that are at the same level as the one selected on top, that is, all databases, all keys in a database, all components under the same key, etc.

The default ARCHICAD database contains numerous preset Keys, Components and Descriptors, as well as the Unit set, listed at the very bottom.


You can remove selected databases or database items with the Delete button at top, or create new databases or database items with the Create pop-up list at top right.

Important: When you leave this dialog box and click Yes in the Save Changes dialog box, ARCHICAD overwrites the corresponding database files with your changes.

The database files can be saved to the List Templates subfolder of the ARCHICAD Library folder. When creating a new database, a set of new files is generated using the name of the new database.

In addition to the _KEY (keys), _COMP (components), _DESC (descriptors), _UNIT (units) and _CRIT (criteria assignment) files, a new _SCHEME (list scheme) and _MASTER_GDL files are also created.
