Parametric modeling with LLM agents and solver

The evolution of computer-aided design has reached a turning point with the incorporation of generative artificial intelligence. Traditionally, CAD models were built using parametric scripts that required deep knowledge of the kernel's geometric constraints. However, the emergence of large language models (LLMs) has opened the door to automated CAD code generation, but the industry demands more than syntactically valid scripts: every operation, every assembly, must be accepted by an exact geometric engine, and it must also preserve parametric editability. This is where concepts such as solver-based LLM agents —like those explored in Embodied CAD research— become relevant. These agents do not generate the complete model in a single pass; instead, they iteratively select actions from a skill library, resolve them into typed geometric operations, execute them on a CAD backend, and use solver feedback to plan, repair, and learn. This approach dramatically reduces assembly errors and enables tackling multi-component tasks in mechanical and industrial contexts.

From a business perspective, the ability to automate parametric design processes with AI agents represents a significant competitive advantage. Companies that adopt AI for businesses can accelerate prototyping cycles, reduce human review costs, and ensure precision in complex assemblies. At Q2BSTUDIO, we understand that integrating artificial intelligence into technical workflows requires both deep domain knowledge and robust infrastructure. That is why we offer custom applications that allow incorporating parametric modeling, solver-based planning, and reinforcement learning into real production environments. Our team develops custom software that adapts to the specific needs of each industry, whether in the machinery, industrial equipment, or mold sectors.

Furthermore, the implementation of these intelligent systems cannot be separated from security and cloud scalability. Design data management, communication between agents, and model storage require protected environments. Therefore, our AWS and Azure cloud services provide the foundation to deploy AI agents securely, with high availability and regulatory compliance. Likewise, business intelligence plays a key role: analyzing performance metrics of generated CAD models, execution times, and success rates allows continuous process optimization. With tools like Power BI, we offer business intelligence services that transform simulation data into actionable insights.

However, process automation through AI agents also poses cybersecurity challenges. Attacks on industrial design workflows can compromise intellectual property or alter critical geometries. Therefore, at Q2BSTUDIO we integrate cybersecurity into every layer of development, from validating generated code to encrypting communications between the solver and the assembly database. Our experience in AI agents includes creating controllers that learn from solver feedback, as proposed in reward-based planning approaches, ensuring that every action is geometrically coherent and editable.

In short, the convergence of LLMs, geometric engines, and reinforcement learning is redefining parametric assembly design. Companies seeking to lead in this field require technology partners capable of developing custom applications, integrating artificial intelligence securely, and scaling their operations with AWS and Azure cloud services. At Q2BSTUDIO we offer precisely that: complete solutions ranging from parametric modeling to business intelligence, including cybersecurity and process automation. Thus, we transform the challenges of AI-assisted engineering into real innovation opportunities.
