This research solves the challenge of using LLMs for Computer Aided Design by introducing a hierarchical domain-specific language that enables effective geometry generation and spatial reasoning.

• Overcomes LLMs' limitations in spatial reasoning through specialized solvers
• Introduces a structured approach for complex geometry planning
• Simplifies CAD creation through natural language interpretation
• Enables non-experts to create sophisticated designs via text prompts

For engineering teams, this breakthrough transforms how design tools can be accessed, allowing AI to translate concepts into precise technical specifications without deep CAD expertise.
