CAD Interoperability Challenges and Solutions

This technical report addresses the ongoing challenges in CAD interoperability, focusing on the difficulties faced by CAD, CAE, and CAM software applications in reading competitive products without the need for translation to neutral formats. The report outlines the significance of Product Management Information (PMI) in replacing traditional 2D drawings with semantic representations. It details the industry's requirements for sharing CAD data through digital twins and threads, emphasizing the relationship to ISO standards and the need for effective validation processes. The report also discusses the barriers to model-centric data interoperability, motivations for reducing downstream errors, and the importance of collaboration among OEMs, suppliers, and software solutions. Additionally, it highlights the growing complexity of CADx files and the need for efficient visualization and validation methods. The report concludes with insights into the evolving landscape of additive manufacturing and the necessity for software solutions to adapt to these changes while ensuring compliance with industry standards.
