Preferences

You can access Bevel Preferences using the toolbar icon or by going to the menu Extensions->Bevel->Preferences.  Settings within this dialog are immediately applied when they are changed.

Operation Notifications

Some features such as Clean Edges and Auto-Soften will display notifications to report what was changed in the model.  These notifications may be disabled if desired.

Setting the Language

Choose a language from the dropdown menu.  You will need to restart SketchUp for the new language to take effect.

Rounding

This option was added with the release of Bevel 1.1.0. Select whether to round edges using a true Arc or a Bezier curve profile.  Arcs allow you to set a specific circular radius for the rounding while Bezier curves can provide slightly better smoothing at Bevel borders. 

Auto Soften Edges

The settings in this area are used by the Auto-Soften Edges feature.

Harden Borders

The settings in this area are used by the Harden Borders feature.
