The paper examines the automation of CAD 2D (2-dimensional) technical drawings based on CAD 3D (Computer Aided Design 3-dimensional) solid models and also the design of the abovementioned solid models based on 2D technical drawings. In this context an automated two-way design approach is discussed. This approach utilizes selected capabilities of artificial intelligence (AI) tools, such as large language models (LLMs). In particular, it focuses on the design of grinding tools (mainly grinding wheels). The first part of the study focuses on the AI-assisted solid modelling and utilization of created solid models to generate their 2D drawings by using *.dxf format. In the second part, the author investigates the possibilities of designing 3D solid models using 2D drawings rather than relying exclusively on text-based prompts. The final results demonstrate that the presented procedures can be used by designers, while also taking into account the limitations of the approach. The results indicate that human actions and skills are still required to improve and finalize the project. Moreover, the study demonstrates that selected LLMs are a cost-effective solution for the basic two-way CAD design of grinding tools.
