Abstract

Parametric CAD systems such as SolidWorks and Fusion 360 require a high degree of manual intervention in the form of geometry definition, constraint application, and iterative refinement. CAD-Genesis is a free open-source add-in that helps overcome these challenges in the form of a CAD system that directly converts the description of a concept in a natural language format, and reference images into native editable parametric models and assemblies. It includes dynamic sliders for instant dimension control, a history mechanism that ensures a high degree of completeness, forward-looking validation of the integrity of the model, optimization suggestions in terms of mass and performance, integrated educational guidance on the basics of SolidWorks, and cross-platform interoperability between the two systems. By leveraging advanced language models and the API of the CAD systems, the add-in is able to bring a productivity improvement of 60–70% in the form of compressed concept development time in regular engineering activities [1], [2]. CAD-Genesis is a native-built system with an MIT license that allows the development community at large to contribute towards the evolution of the capabilities of the system in a multitude of professional and educational settings.
