 On Windows platform when using Visual Studio compiler there is a possibility to start the debugger automatically if an exception is caught in a program running OCCT. For this, set environment variable *CSF_DEBUG* to any value. Note that this feature works only if you enable OCCT exception handler in your application by calling *OSD::SetSignal()*.

 @section occt_debug_bop Self-diagnostics in Boolean operations algorithm
 
 In real-world applications modeling operations are often performed in a long sequence, while the user sees only the final result of the whole sequence. If the final result is wrong, the first debug step is to identify the offending operation to be debugged further. Boolean operation algorithm in OCCT provides a self-diagnostic feature which can help to do that step.
