CATIA agents: delivered workflows and a useful pilot
What the supplied profile describes
The technical profile describes delivered AI agent applications in CATIA design automation, fixture design and aerospace structures. Agents connect parametric modeling with RAG knowledge, Function Calling / MCP and single- or multi-agent workflows. Private/local, API and edge deployment are delivery options.
A five-stage engineering engagement
The stated process moves through requirements and process decomposition, knowledge/tool connection, orchestration, integration/deployment, and evaluation/operation. LoRA tuning of Qwen / Llama and dedicated enterprise-model training remain on the development roadmap.
Start with a decision, not a demo
A useful pilot asks whether one defined workflow is worth integrating. Describe the inputs, variations, expected output and conditions in which the task must stop for human review. This creates a testable question rather than an open-ended promise.
Use the current process as a real alternative
Existing CAD tools already support mechanisms such as parameterization, rules and reusable knowledge. The relevant alternative may be a maintained template or script. Compare the proposed workflow with that baseline, including setup and maintenance effort.
Measure the complete task
Record preparation, automated execution, review, correction and final handoff. A fast generation step is not enough if the output needs extensive rework. Check native editability and whether the result meets the same engineering rules.
Agree what success would change
Define the acceptance conditions before evaluation. If the pilot passes, the next decision might be a second part family or a restricted integration. If it fails, record the limiting inputs and avoid extending the conclusion beyond the tested workflow.
Define the task envelope before the first run
Create a small representative task set with common cases and known failure cases. State the accepted inputs, permitted tool actions and points where the workflow must stop for engineer review. Success criteria should be agreed before testing so the benchmark measures engineering behavior rather than the persuasiveness of a demonstration.
Validate the engineering artifact
Check that the CATIA file opens correctly, expected features and parameters exist, constraints remain solvable, naming and unit conventions are respected, and the model remains editable for downstream work. Use deterministic CAD/rule checks wherever possible; reserve human review for requirements that cannot be expressed as pass/fail rules.
Track intervention, recovery and traceability
Record tool errors, retries, unnecessary actions, human interventions and recovery after a failed operation. Preserve the request, major tool actions, CAD revision and approval so a result can be reviewed later. A held-out regression set should be rerun after changes to prompts, tools, knowledge sources or models.

It also lists RAG, Function Calling / MCP, multi-agent workflows and private deployment capabilities."], ["Can the system run within our enterprise?", "Private and local deployment are offered. The agreed architecture must identify model hosting, knowledge storage, tool connections and any external dependencies to meet your data boundary."], ["Is domain-model training already released?", "The profile identifies Qwen / Llama LoRA domain tuning and enterprise-model training as work in progress. They require a separate development scope."]]
