Reusability and flexibility in parametric surface-based models: A review of modelling strategies

Abstract

CAD systems are indispensable tools in the product design and development process. Through the creation of parametric 3D models, they increase productivity, enable the design of highly complex parts, improve collaboration between different work teams and reduce time to launch. Nevertheless, during the design process there are many different modelling solutions to generate any one part, and the robustness and flexibility of a model depends to a great extent on the experience of the designer. This dependence on individuals rather than methodologies has a negative impact on downstream engineering activities, as many models are not easily editable. Developing a methodology to produce flexible and reusable 3D models is therefore key to reducing the design time of the product development process. In this paper, we review the state of the art with regard to flexibility and reusability in parametric surface-based models. We identify gaps in the field and determine the principle aspects in CAD development workflows which influence flexibility and reusability. We aim to expand the field of knowledge and establish a foundation for future research into the development of a surface-based modelling methodology.
