The quality of mechanical 3D models generated with Computer-Aided Design (CAD) systems is a key aspect of the product development process. Evidence shows that formal modeling methodologies contribute to creating higher-quality 3D models that improve design performance, but little attention has been drawn to actual practices in industrial companies. Some of the challenges involved in studying these strategies include lack of access to what is often considered an intellectual asset for organizations and thus kept secret, as well as the variety of industrial products and different levels of automation for a particular design within the organization. In this paper, we describe the process of creating a comprehensive assessment instrument for diagnosing the level of awareness of CAD quality among the different stakeholders involved in the product development process and the extent to which organizations have implemented strategies to leverage and promote the creation and use of high-quality parametric CAD models. The survey instrument contains questions about key aspects of 3D CAD model quality, from methodologies to training. A formal survey validation process was conducted using the expert judgement technique. The modified Kappa coefficient was used to identify questions that needed improvement. The final version of this instrument is provided in the appendix.
