Option 

Description and default value 

General 

 

Show full diagnostic 

This option specifies whether to show diagnostic messages produced when generating sequence diagrams.
If this option is True, the parser can report detailed progress as it runs.
The default value is True.  

Generate sequence diagram 

 

Depth of call nesting 

During sequence diagram generation, this value limits how deep the parser traverses the source code calling sequence. This value can help keep the generated sequence diagram from becoming so large that it is unusable. You may want to use this option as a means for quickly generating a high-level sequence diagram for a complex method by using a low call nesting value (1-3). Based on the results of your diagram, you can choose to look deeper and/or create additional sequence diagrams for each of the major methods uncovered.
The default value is 10.  

Include messages to self 

This option specifies whether to show messages to self on the generated sequence diagram. If this option is True, messages to self are shown.
The default value is True.  

Generate source code 

 

Never change existing code 

If this option is True, existing code can never be changed when generating source code from a sequence diagram.
If this option is False and some source code already exists, a confirmation dialog opens when you generate source code from a sequence diagram, and you can choose whether to modify the existing code.
The default value is True.
