Abstract: On the basis of describing the relationship between features, tabular layout of
article characteristics, design with features and parametric design, the paper proposes an insight
into how to parameterize parts/components on general CAD systems. Based on the research of
customized development on Inventor, the methodology of building parametric parts/components
library and developing key implementation code on Inventor is put forward. Instance of case study
is performed and demonstrates the feasibility of the methodology.

Key words: rapid design, parametric design, customized development, part and component
library
