Zeta Alpha now understands 3D CAD and connects the dots to engineering knowledge

Manufacturing companies sit on large volumes of product and process knowledge spread across documents and systems. 3D parts libraries, for example, store critical engineering data that’s invisible to everyday search and knowledge workflows. This often results in duplicate designs, slow reuse, and long investigations when something breaks or changes. The information you need exists, but it’s hard to find and connect.
Let’s take part reuse as a concrete example. Everyone knows reuse beats redesign, but in large parts portfolios it breaks down when the right candidate can’t be found quickly, or when the evidence needed to reuse it safely is scattered. When reuse works, it reduces inventory complexity and cost, shortens lead times, and improves quality by relying on proven components. So the bottleneck is findability: teams need to reliably discover the right existing part and the supporting context.
What’s new: 3D CAD in Zeta Alpha’s knowledge workflows
Building on the advances in multimodal AI we’ve introduced a new generation of Zeta Alpha agents specialized in manufacturing and engineering knowledge. Bringing 3D CAD into the same workflows as documents and tabular data, the agents can reason over 3D geometry and functionality to deliver answers grounded in your technical sources.
In this short demo, we go from a 3D assembly to action: identifying replacement parts, generating a supply-chain risk report, asking the agent to explain the geometry and function of the assembly, and then proposing and comparing a lightweight variant in a structured report. The goal is faster reuse and better decisions, grounded in your engineering sources.
You can also search the way engineering work actually starts: by describing what you need in plain language, by using the CAD geometry itself, or even by uploading an image of a part. This makes it much easier to find candidates when names and metadata are inconsistent, and to jump from a match straight into the related context.
Why CAD needs context (and how we connect the dots)
Beyond LLMs being able to “read” CAD data, the context that makes this information actionable is scattered across PLM/PDM, BOMs, test reports, manuals, supplier data, cost spreadsheets and more. The real challenge is stitching these silos into a consistent, permission-aware view of the truth, so answers come with the right context and traceability. And this is where Zeta Alpha’s Agentic RAG system really shines.
The platform combines GenAI with targeted retrieval from your approved sources, so answers are grounded in your actual engineering data. “Agentic” means it can take multiple steps across systems: search across sources, pull the most relevant evidence, and assemble it into a clear response. Crucially, it keeps permissions and source traceability intact.
“When 3D geometry is embedded into the same vector space as text, you can fly through this whole map of your entire parts portfolio to analyze supply chain risks and find replacement candidates.”
Reuse at scale: risk and replacement planning
Once geometry and part metadata are represented consistently across your parts library, you can move from part similarity to portfolio-level questions. For example, engineering and procurement teams can identify which part families are approaching obsolescence risk this quarter, and automatically surface viable replacement candidates, grounded not just in shape and functional requirements, but also in the connected context like supplier information, availability, and price from other systems. The result is a faster, more proactive way to reduce risk and keep lead times and cost under control.
If you’d like to see this on your own parts library and engineering documentation, get in touch for a short walkthrough or pilot. We’re excited to learn which reuse and risk workflows matter most in your organization.
