When the user enters dimensional data in any window, the units applied are taken from default settings. The default units are specified independently for each unit type. To change the default units, select Settings > Units to display the Current Session Units window.

To set the default units for a specific project the administrator must select the required units using the Current Session Units window and click Save. A file, %AVEVA_DESIGN_USER%/xxx-save-current-units-Met.pmldat or %AVEVA_DESIGN_USER%/xxx-save-current-units-Imp.pmldat is then created. The created file must be copied to the project defaults folder and renamed to %xxxdflts%/project-current-units-Met.pmldat or %xxxdflts%/project-current-units-Imp.pmldat. The user is then permitted to use the Project Defaults or use a saved file created by them.

On Global projects, it is necessary to propagate the units settings file to all project satellites. If the “Other Data Transfer” mechanism has been implemented, refer to Transfer of Other Data, then project units settings files could be propagated in this way. Otherwise, the most practical method of propagating a project units file is simply to e-mail the file to all satellites and have the file copied to the appropriate project folder. In practice, project units files will be configured at the beginning of a project, and are unlikely to be changed frequently during the life of a project.

The User Settings, Save and Restore buttons can be disabled by the administrator which forces the user to use the project default settings. To disable the buttons, the administrator must open the file saved in the project defaults folder and change the following line:

The Save and Restore buttons are now disabled.
