%X This paper introduced the freeform feature modeling in HUST-CAID, defined classification and parameters combining with the HUST-CAID system (computer aided industry design system developed by Harbin University of Science and Technology), creating a freeform feature by this classification and parameterization. On the basis of configuration of FFDP,put forward a framework for attaching freeform feature. The framework can make freeform feature model be parameterization. Then, on the basis of the framework, this paper researched a validity maintenance for the freeform feature with attachment, which could keep the validity of freeform feature with attachment.
