I Extended FreeCAD MCP After 1.5 Hours of Assembling Through Chat. Then the Agents Built It Alone

Описание и применение

Автоматизированные агенты смогли собрать пан‑тильт механизм за 15–17 минут, но при этом неверно разместили боковые пластины; проверочные инструменты не выявили ошибки, показывая лишь точность измерений.

Задача

Automated CAD assembly agents required extensive human guidance and produced incorrect part placements, revealing limitations in current tool checks.

Результат

The extended MCP server enabled automated assembly in under 20 min, but the built‑in checks only verified metrics the agents declared correct, not the semantic correctness of part placement.

Рабочий процесс

• 1. Forked hram/freecad-mcp and added new alignment/verification tools.
• 2. Ran Claude to assemble the archive autonomously.
• 3. Ran Codex to assemble the archive autonomously.
• 4. Compared agent outputs to expected geometry and inspected check results.
• 5. Analyzed why checks failed to catch swapped side plates and added spacers.

Доказательства

The agent executed CAD operations, but I was the one assembling, through a chat. It took 1 hour 37 minutes, and the base was still unassembled.

Источник

Claude and Codex each assembled the same mechanism on their own, in about 15 and 17 minutes.

Источник

Codex had swapped the two side plates.
