| Abstract: |
| Feature modelling has been received wide respect in recent years，and is becoming the efficient method to achieve the new generation of CAD．This paper firstly gives the formal defenition of feature，then offers a form feature based respresentations of objects，at last provides an important model in the applied modelling system，namely form feature modelling． |
| Key words: Feature,feature modelling,form feature,constraint． |
