This paper presents a methodology and an application presented by the authors in previous publications. The application is integrated into SolidWorks and it’s used to automate the design process of modular fixturing devices. Included in it is a methodology for automated determination of the positions of the clamping elements. Both the application and the methodology are using rule-based logic and mathematical formulas.
