BOTTOM LINE
The right AI for CAD isn't the one with the best demo — it's the one that integrates with how your team actually works and makes engineering decisions faster and more reliable. Tools built on general language models can't replace the domain depth that mechanical engineering requires.
Start with a pilot on one workflow, measure the time impact, and expand from there. The teams seeing the biggest ROI are those treating AI as a technical colleague, not a search engine.
Compare AI copilots for SOLIDWORKS: Leo AI, Design Assistant, AURA, and Onshape AI Advisor. Honest assessment of what works, what's still in beta, and what actually helps engineers.
Choosing the best AI copilot for SOLIDWORKS is a balancing act. No single tool checks every box for every team, so the decision comes down to weighing what matters most in your environment.
Integration and compatibility determine whether a copilot fits into your existing stack without friction. Use case fit matters because a tool designed for early-concept generation serves different needs than one built for answering technical questions. Data security and IP control are non-negotiable for teams handling proprietary designs.
And then there's the elephant in the room: most of the AI tools announced for SOLIDWORKS are either in beta, limited to specific platforms, or not yet shipping the features shown in demos.
Let me break down what's actually available, what works, and what you should realistically expect.
Comparison Table: AI Copilots for SOLIDWORKS Users
Platform | Primary Focus | Availability | Enterprise Adoption | Best For |
Leo AI | Engineering copilot for knowledge, calculations, part search, concept generation, and design inspection | Available now | HP, Scania, Intel, Mobileye (60K+ engineers) | Teams wanting production-ready AI that works with existing CAD/PLM |
Design Assistant | Automate selections, mates, and sketching predictions | Available in SOLIDWORKS Cloud | Limited (cloud users only) | Engineers already on SOLIDWORKS Cloud wanting faster modeling |
AURA | Conversational AI for help, documentation, and 3DSwym insights | Beta (3DEXPERIENCE only) | None yet (still in beta) | 3DEXPERIENCE users who want in-context help |
Onshape AI Advisor | Learning assistant for Onshape workflows and best practices | Available now | Growing (1.5M+ Onshape users have access) | New Onshape users and teams learning the platform |
IN PRACTICE
What Engineers Are Saying
"The geometry search has been invaluable — helping me find standard parts instead of designing new ones, saving a huge amount of time and effort. The search system is smart and CAD-aware. It was made by people who truly understand the struggles of mechanical engineers."
— Eytan S., R&D Engineer, Mid-Market
1. Leo AI: The Production-Ready Option
Leo AI is an engineering copilot built specifically for mechanical engineers. Unlike the other tools on this list, Leo doesn't try to replace your CAD software or live inside a specific platform. It works alongside your existing tools.
What Leo Actually Does
Leo is built on a proprietary Large Mechanical Model (LMM) trained on mechanical parts, assemblies, and engineering logic. This means it understands context in ways that generic AI chatbots simply cannot.
Core capabilities:
Technical Q&A: Answers engineering questions grounded in 1M+ verified sources (engineering books, standards, datasheets), not random internet information
Part search: Finds parts from your PLM and 120M+ vendor parts using natural language ("find me a stainless steel bracket similar to what we used on the X project")
Engineering calculations: Runs formulas with full traceability to trusted sources, exportable to Excel
Concept generation: Creates 3D mesh concepts and 2D sketches from text descriptions, specs, or hand-drawn sketches
Documentation: Generates engineering documents including BOM, statement of work, manufacturing methods
Who's Actually Using It
This is where Leo stands apart. It's not a demo or a beta. It's in production at HP, Scania, Intel, Mobileye, and over 60,000 engineers globally. Distributed through value-added resellers in the US, UK, India, France, Germany, Poland, Benelux, and Israel.
Measurable results from deployments:
34% reduction in design errors
32% increase in part reuse
5-7 hours saved per engineer per week
The Security Piece
SOC 2 certified, GDPR compliant, with zero training on customer data. For enterprise teams handling proprietary designs, this matters.
Honest Limitations
Leo generates 3D mesh concepts, not native SOLIDWORKS files. The mesh needs to be exported and refined in your CAD tool. It's not trying to replace SOLIDWORKS. It's trying to make everything around the CAD work faster and more accurate.
Best for: Engineering teams who want AI that's actually in production, integrates with existing workflows, and delivers measurable results.
2. SOLIDWORKS Design Assistant: Native but Limited
Design Assistant is an AI and machine learning toolset built into browser-based SOLIDWORKS Cloud. It learns from your individual design habits and offers real-time suggestions for selections, mates, and sketching.
What It Actually Does
Selection Helper: Predicts which edges, faces, or bodies you'll want to select next based on design intent
Sketch Helper: Analyzes sketch entities and suggests additional instances with dimensions and relations
Mate Helper: When inserting components, suggests locations for replication
Smart Mate: Creates fully constrained mates automatically
These are genuinely useful features for speeding up everyday modeling tasks. The tool learns your patterns and gets better over time.
The Catch
Design Assistant only works in SOLIDWORKS Cloud (browser-based). If you're using desktop SOLIDWORKS, which is still the vast majority of the 7.5 million SOLIDWORKS users globally, you don't have access to these features.
The features that do exist in desktop SOLIDWORKS are more limited: Command Predictor, Fastener Recognition, and some Xpert tools (SketchXpert, FeatureXpert, etc.). These are helpful but not the full AI assistant experience shown in marketing materials.
Honest Assessment
Design Assistant delivers real value for the specific tasks it handles. But it's not a comprehensive engineering copilot. It's a modeling accelerator for users already committed to SOLIDWORKS Cloud.
Best for: Engineers already using SOLIDWORKS Cloud who want to speed up repetitive modeling tasks.
3. AURA: The Documentation Layer
AURA is Dassault's documentation chatbot trained on SolidWorks help files and community docs. It answers how-to questions: "how do I create a sweep feature?" "how do I suppress a configuration?" It is still in beta after launching in July 2025. The headline features shown at 3DX World 2025 (assembly generation, geometry from text) remain on the roadmap as "coming soon."
The critical blocker: AURA requires 3DExperience Connected. Traditional desktop SolidWorks users cannot use it at all. This locks out approximately 85% of SolidWorks licensees. For the small percentage on cloud-based 3DExperience, AURA is useful for command lookup but does not generate geometry, does not run topology optimization (that is SolidWorks Simulation, a separate product), and cannot search your PDM vault.
The knowledge gap AURA does not fill: "does this part already exist in our vault?" "what assembly constraints did we use last time for a similar design?" "what are the DFM issues with this geometry?" Those are the gaps Leo was designed to fill. When your team runs into the question "does this part already exist?" or "what are the DFM issues with this assembly?"—that's where Leo operates, on any SolidWorks platform, desktop or cloud.
