Local RAG for CAD API: Overcoming Knowledge Gaps in Proprietary Interfaces

An engineer faced the need to automate tasks in Smart3D, but knowledge of the API was a bottleneck. He built a local RAG pipeline: decompiled libraries, extracted facts, enriched them via LLM, created embedding indices, and implemented an agent with verification — so the model generates code based solely on real API entities.
