Abstract : The Model-based Definition (MBD) approach represents a trend in Computer-aided Design (CAD) that can increase productivity and competitiveness by both reducing time-to-market and improving product quality. Its main goal is to improve and accelerate the design, manufacturing and inspection processes by integrating drawing annotations directly onto a 3D model; thereby obviating the need to generate engineering drawings. Today, CAD tools and international standards support the MBD concept; however, among those companies willing to adopt it, there is a growing need for a procedure that will help them identify and minimize the impacts as well as maximize potential gains as they move from a 2D drawing to an MBD environment. Based on observations from 34 interviews conducted within the Engineering, Drafting, Configuration Management, Airworthiness and Certification, Manufacturing, Inspection and Knowledge Management departments at two Canadian aerospace companies, the objective of this paper is to propose a series of guidelines that focus on the important aspects, considerations and implications that should be taken into account during the MBD transitioning process.
