Abstract: Dimension (parameters) driven method and program-driven method are two kinds
of parametric design methods of SolidWorks secondary development. This paper proposes a
combined parametric design method after studying and comparing the advantages and
disadvantages of the existing two parametric design methods, and it is classified as two forms of
series and parallel based on implementation ways. The study shows that it can make full use of the
advantages of both dimension driven method and program-driven method. The paper develops a
program based on Microsoft Visual C++6.0, which verifies its superiority in designing complex
parts.
