How do I default to "off" for Object Snap?

Tools => Snap Setup

By default, Object Snap in the Snap Setup dialog box (Tools => Snap Setup) is set to on. You may change the default setting for a new project in the Sonnet initialization file. Do the following:

1. Open the Sonnet Initialization file by selecting Admin => Diagnostics Edit sonnet.ini File from the main menu of the Sonnet task bar.
   
   The sonnet.ini file is opened in your default text editor.
    

2. In the [ xgeom] section of the sonnet.ini file, add the following line:
   
       ObjectSnap=off

3. Save the Sonnet.ini file.

This setting will be changed the next time you start Sonnet software.
