In an increasingly interconnected world, effective communication with digital design software is paramount. This thesis addresses the challenge of enabling engineers, designers, and creators to communicate with Rhino 3D software through an interactive, user-friendly natural language interface.Many users, including new students and experienced individuals unfamiliar with Rhino, often struggle with using the correct instructions to fully utilize the software's capabilities. This challenge impedes them from leveraging the software's full potential. To address this issue, this thesis presents an integrated system that combines Large Language Models (LLMs) with the Rhino API, facilitating intuitive communication with the software.The objectives of this thesis included developing this integrated system to make Rhino accessible to users with limited prior knowledge and empowering experienced users to explore advanced capabilities. The methodology employed large language models such as GPT-4, coupled with the Rhino API, and focused on prompt engineering techniques to effectively instruct and interact with LLMs. This process involved crafting precise and context-aware prompts, breaking down tasks into step-by-step instructions, and iteratively refining prompts through interactive dialogues.The findings of this research highlight the feasibility of the proposed interface in enhancing user interaction with digital design software, promoting accessibility and facilitating a better learning environment in the field of modeling and design. While the system has shown promise in bridging the gap between natural language and complex software commands, it primarily serves as a proof of concept at this stage.In conclusion, this thesis establishes the foundational work for future enhancements and applications, indicating potential paths for transforming human-computer interaction in parametric design. The focus remains on proving the concept and assessing feasibility, with subsequent research needed to realize its full transformative potential.
