Default Settings Editor
The Default Settings Editor sets the values that Cygnus applies automatically as you work, so you do not have to configure each new workspace and study from scratch. It shows two sets of defaults side by side: Application Defaults and Workspace Defaults.
- Application Defaults are assigned to a workspace's defaults when you create a new workspace.
- Workspace Defaults are applied to each new study you create in the current workspace.
To open the Default Settings Editor:
- Click Edit → Default Settings on the menu bar.
You can also click the Default Settings button on the toolbar.

Settings
Each set of defaults offers the same fields.
