The invention discloses a rapid rocket three-dimensional model design information extraction system which comprises a system main control module, a model selection module, an information extraction module, an information setting module and an information output module, wherein the system main control module sends instruction information to other modules in a message mode; the model selection module selects a three-dimensional model in a current design environment; the information extraction module extracts rocket three-dimensional model design information; the information setting module resets the rocket three-dimensional model design information which is output by the information selection module; the information output module outputs the three-dimensional model design information which is output by the information setting module. According to the rapid rocket three-dimensional model design information extraction system, the rocket three-dimensional model design information extraction efficiency is improved, the operation load and error probability in an information extraction process are reduced, and the production development period is shortened.
