Internet-driven collaborative design technology opens up another domain for building new engineering design environment, which is Internet-centric, global and distributed. A novel approach of 3D feature modeling with form feature, parameterized form feature and parameter list of the form feature was developed. Any change of the shared models can be viewed by the modification of the parameter of the form feature, and then parameter lists were modified so that new models were recreated through accessing the log of feature modeling. A supported design platform based on CORBA/Java was presented, which was of high-performance, scalability, maturity, interoperability, support for legacy systems and ease of development. Through the platform, all the applications, 3D feature models dispersed on the remote heterogeneous systems, can be encapsulated into the objects what CORBA agent objects can manage and find.
