Abstract—Because the 3D model is closer to the real product, 3D
Model-based design not only speeds up the product design
process, but also improves the readability of product
information. 3D Model-based Design will be a trend of the
development. It is necessary to add all kinds of product
information, including design knowledge, into 3D models to
enrich 3D models. In this paper we give the background of 3D
model based knowledge engineering, the definition and categories
of 3D model knowledge, technologies which will be used, and a
technical architecture
