Abstract: To ensure the relevant three-dimensional CAD document to be effectively
packed, the module of three-dimensional CAD-document fast packing is designed in Visual C++
development environment, which adopts SolidWorks API and synchronous development model
of DLL. The module consists of four components: SolidWorks addin plug-in components, user
interface components, assembly traversal components, data files released components, which
can quickly send assembly document and all sub-assemblies, parts, drawings to the specified
directory.

Key words: fast packing, customized development, SolidWorks, DLL
