There are two different types of predefined settings in the ARES Commander.
System or User Settings and drawing setting. The System and user settings are available to the user, whereas the drawing settings are only available when a drawing is active.

While the system or user settings are saved in your user profile, the drawing settings are saved directly in the drawing.

Both types of settings are available in the Options dialog box.
​
A search field lets you find a specific setting.

You can also save a set of settings in a profile in the Options dialog box. These profiles can be exported and imported. You can also switch between several saved profiles.

There are several ways to find the settings you are looking for. Several buttons on various ribbons, toolbars, and on the status bar lead directly to the corresponding option within the Options dialog box. As an alternative to the Options dialog box, you can set certain preferences using system variables.
