• All ida-python
• Class based design, error logging
• RTTI parsing algorithm scanning for vtables first (instead of bruteforcing the entire rdata/data sections)
• Graphing of class hierarchy (using transitive reduction for clarity)
• Export functionality to GraphViz (.dot) format
• Handles RTTI and C++ name demangling for:
  • X86 GCC
  • X86 MSVC
  • X64 GCC
  • X64 MSVC

Simple: First load your binary in IDA. Then run script classinformerpython.py To export the dot file, either right click on the class diagram and select export or just hit F2.
