Abstract: Aircraft and other complex product design process is becoming a full three-dimensional
process. It is quite important to create and maintain model accurately and quickly, which significantly
affect the product design cycle. Parts rapid modeling can effectively improve the efficiency of
three-dimensional model creating, while it is limited to create a single part quickly. Associated design
makes a rapid component modeling possible. Focused on these questions, this paper studies the
combination of associated design and rapid modeling, presents a detailed method combining associated
design techniques with wing components rapid modeling and verifies the effectiveness of the model
through a rapid modeling tool based on such technique.

Key words: three-dimensional model, associated design, rapid modeling, rapid amending
