Abstract：During full 3D design process, MBD model has become a accurate and real-time single data source,
which integrate into all kinds of information about design, inspection, manufacture and assembly. MBD model realizes
digital manufacturing and assembly, without two dimensional drawings. Fasteners have various types and the number of
fasteners is more than half of the total number of parts. Based on the characteristics of low design & assembly efficiency
and low accuracy of fasteners, this article introduces a new expression for fasteners, analyses the organization of the relative
information about the fasteners to establish standardized design & assembly expression. To consider all factors, such
as the position of the components, the load demand and the degree of deformation, designners decide the specifications of
fastenerand use 3D point-line to express the fasteners under the relative assembly file, which makes design & assembly expression
for fasteners standardized.
