With the development of computer technology, mechanical manufacturing industry has gradually entered the digital development stage. As the latest phase of digital product definition, Model-Based Definition (MBD) technology is a digital definition method, which attaches all the relevant information such as design definition, process description, attributes, and management to the product three-dimensional model (Fan, 2012). The Model-Based Enterprise (MBE) concept is founded on the basis of Model-Based Definition (MBD) (Whittenburg, 2012). The 3D CAD model is the core in the MBE through defining 3D model digitally, allowing designers, analysts, manufacturing personnel, and other users to view various types of information more intuitively, understand the product, and improve the effect of product design and analysis and product reusability.

Model-based definition (MBD) is an emerging paradigm which utilizes 3D-CAD models to carry engineering information. The introduction of CAD tools led to the realization that drawings may no longer be the best method to communicate information. The 3D format offers significant advantages over its 2D counterpart. In addition, adoption of MBD offers significant cost and time savings [14]. One account found that “a savings of more than $3M annually at a single naval facility will be generated by implementing MBD” along with “a 33 percent reduction in the development schedule of new items is expected” and “MBD shall also create a significant reduction in manufacturing errors, which should result in a decrease in the amount of rework, providing significant cost savings.” [18]. Moving forward, model-based definition efforts will be focused on enhancing the model-based definition capabilities beyond drawing information; and this exaptation will likely lead to many unforeseen benefits and opportunities.

Authors in (Huang et al. 2015) developed an effective approach based on sub-part retrieval of 3D CAD models as to be reused in the manufacturing process. 3D CAD models represented by MBD (model-based definition) model. Then codes for accelerating sub-part retrieval are given to filter out unmatched sub-parts efficiently. This approach, evaluates the similarity according to both geometric and manufacturing semantics level.In 2018, (Huang et al. 2018) proposed a new and efficient retrieval approach of 3D CAD models which supports macro process reuse.
