This paper developed a CAD system of modular fixture based on reconfigurable core components by lead reconfigurability theory into modular fixture assembly because of the analysis that modular fixture are reconfigured by different core components. This system makes some fixed and parameterized structure, which can fulfill certain functions as core components, and constructed modular fixture components library. Introduce a store method for typical path and a workflow of the construct design module. The application this system has proved that it can finish the task of modular fixture assembly well.
