Current parametric parts library cannot contribute to the reuse of finite element model. It is essential to remodel
or exchange model for parts in CAE software. This paper presents a synchronous CAD/CAE modeling method,
which can be employed in parts library based on Siemens NX software. Primary CAD and CAE information in part are
merged into master model, which acts as cornerstone for solid model, FE model and simulation model. Thus, part models
from parts library can be directly used into simulation analysis, and parametric amendment and change propagation is
sustained. A software package developed for designers is helpful to search and achieve desired part from parts library.
Three case studies are carried out to clarify synchronous CAD/CAE modeling process and change propagation procedure.
