BOTTOM LINE
The right AI copilot is one that knows your data — not just the internet. Engineering-specific AI trained on your PLM, PDM, and CAD library answers questions in the context of what your team has already built, not what the average engineer does.
Before you evaluate any AI copilot, ask one question: does it know the difference between your approved bracket from 2019 and a new design? If it can't access your data, it's not really a copilot — it's an autocomplete.
Learn how to select an AI copilot that integrates with your PLM, PDM, and CAD library while keeping your proprietary data secure. Discover why engineering-specific AI outperforms generic tools like ChatGPT for mechanical design workflows.
Your CAD data is your gold. Your PDM, PLM, and CAD library are your treasure chest. They hold all your previous designs, which encapsulate your IP and best practices, and represent one of your most significant competitive advantages.
Just like every new engineer joining your company must familiarize themselves with your previous designs to understand your best practices and context, the AI tool you choose must do the same.
Any AI tool worth considering must check all these boxes:
Secure: Keeps your proprietary data protected and doesn't use it to train its AI model
Integrates with your workflow: Connects to your knowledge bases (PLM, ERP, local/network folders) and CAD
Understands CAD files: Not just text files
Delivers substantial ROI: Not just "cool AI," but value that justifies changing how you work today
In this article, we'll break down how to choose the best AI copilot for your engineering team's needs.
How To Choose an AI Copilot That Learns From Your CAD Library
Think about this: you and your friend Joe are both mechanical engineers. You work for NASA, Joe works for HP. You both use your engineering AI copilot and ask for the same thing: "ball bearing."
You expect to get a titanium space-grade bearing. Joe expects to get a standard SKF one.
Same request. Different context. Different expected output.
Your AI copilot must understand your context and best practices. What are your preferred parts and vendors? What are the most common components in your previous designs? What industry do you operate in, and what standards must you follow?
The gateway to this context is your CAD and text libraries.
IN PRACTICE
Conclusion
"The connection to our PDM and using that as a data source is legit the best thing ever. I found three viable bracket options fitting my exact envelope constraints — in minutes, not days."
— Eytan S., R&D Engineer
Why ChatGPT, Gemini, Claude, and Other Generic AI Tools Aren't Enough
Your CAD data contains much more information than the text in its title. No doubt about that.
But doesn't it seem odd that your PDM search tool only helps you search based on part title text? If you're looking for a spring with a constant of 3000 N/m, structural damping of 0.2%, and free length of 750 mm, how exactly is your search bar going to help you find that?
Generic AI tools like ChatGPT, Gemini, and Claude are called LLMs (Large Language Models). They're great at analyzing text. But they cannot read or understand CAD files, which limits their ability to understand your context. While these tools excel at summarizing documents or writing code, they can't interpret assemblies, tolerances, or constraints.
Mechanical engineering demands more than textual understanding. It requires spatial reasoning and specialized knowledge that general-purpose models simply don't have.
Beyond that, these LLMs operate in the browser, completely detached from engineering workflows (PLM, CAD, ERP, folders). This increases the friction and effort required to use them in real time during a design project.
And here's the trust problem: in engineering, every decision should be backed by a legitimate source, whether that's internal guidelines, an engineering handbook, or an industry standard. Recent studies show that 40% of the training data behind these generic AI tools comes from Reddit, a social network of anonymous users sharing unvetted opinions.
So when your fellow engineer asks ChatGPT "how many bolts should I use to seal a pressure cell that holds 500 MPa" and it answers "5 M8 bolts, no O-rings," that answer is essentially citing an anonymous person from somewhere in the world who once posted it on Reddit. No engineering context. No verified knowledge. No trustworthiness.
Imagine the potential risk of trusting these tools in real engineering projects in the medical device, automotive, or defense industry.
Leo: The Engineering-Specific AI Solution
Leo was built by and for mechanical engineers. It uses a patented proprietary AI model, the first designed to understand CAD files. It integrates into your engineering workflow securely (SOC 2 certified, GDPR compliant) and seamlessly connects to your PLM, PDM, CAD, ERP, and local/network folders.

Which AI Copilot Is Best for Mechanical Engineering?
When selecting a copilot, engineers should prioritize one designed specifically for mechanical engineering. This comparison makes the difference clear.
Generic AI Assistants vs. Leo: The Engineering-Specific AI
Feature | Generic AI (Gemini, ChatGPT) | Leo AI |
Understanding of engineering and geometric context | No awareness of CAD, assemblies, or mechanical constraints | Fully understands CAD models, assemblies, constraints, tolerances, and engineering workflows |
Engineering calculations | Limited support; often requires manual verification | Built-in validation, calculations, and references to ensure accuracy |
CAD and software integration | No integration; works outside engineering tools | Works directly within CAD and engineering software, maintaining workflow continuity |
Data security | Inputs may be stored or used externally | Keeps sensitive company and design data secure |
Workflow assistance | Primarily generates text | Supports part search, documentation, onboarding, and automates repetitive engineering tasks |
