3D parts and Assemblies

Understanding how mechanical engineers describe 3D shapes and assemblies is essential for enhancing communication and efficiency in design. This research explores the specific terminology used by engineers and how descriptions vary across mediums—physical 3D printed models, digital models, and AI-generated descriptions. A user study with engineering students and professionals gathered diverse perspectives on a set of 3D parts and assemblies. The study revealed significant differences in descriptions based on the medium, with 3D printed models emphasizing tangible features and digital/AI descriptions being more abstract. Insights into the cognitive processes of interpreting and describing 3D models were gained, and the accuracy of AI-generated descriptions was evaluated through participant ratings and feedback. These findings highlight both the strengths and limitations of current AI technology and contribute to a better understanding of engineering terminology. Ultimately, the research aims to improve design communication and foster more effective collaboration among engineers and stakeholders.
