AI integration in SOLIDWORKS means embedding intelligent algorithms directly into CAD workflows to automate routine tasks, improve design precision, and support better engineering decisions. For enterprises, the value proposition is straightforward: compress cycle times and elevate engineering quality.
But here's the reality check. Most of what you read about "AI in CAD" is marketing hype mixed with conference demos that may or may not ship. This guide separates what's actually available today from what's coming, walks through a practical adoption path, and helps you evaluate whether these tools are worth the investment for your team.
What AI Features Actually Exist in SOLIDWORKS Today
SOLIDWORKS 2025 introduced several AI capabilities, with more arriving in subsequent feature deliveries. Here's an honest breakdown of what's available and what each tool actually does:
Production-Ready Features (Available Now)
AI Fastener Recognition identifies nuts, bolts, and washers from non-Toolbox parts and applies SmartMates automatically when you insert them into assemblies. According to GoEngineer's coverage of SOLIDWORKS 2025 FD03, this feature works on custom parts, parts from online catalogs, and even non-SOLIDWORKS file formats like STEP. You'll see a sparkle icon when SOLIDWORKS recognizes a fastener.
This is genuinely useful. Hardware insertion at the end of a design project is tedious work, and automating mate application for dozens or hundreds of fasteners saves real time.
Command Predictor (Beta) anticipates your next SOLIDWORKS command based on your current session and provides shortcuts. It learns from your workflow patterns and surfaces relevant tools before you search for them.
Selection Helper learns your selection intent (edges, faces, features) and accelerates repetitive pick operations. When you're selecting edges for fillets or chamfers, it identifies similar or symmetrical edges and predicts what you're likely to select next.
Smart Tools (SmartMates, Smart Fasteners) have been in SOLIDWORKS for years and automate repetitive CAD patterns during assembly work.
Beta Features (Require 3DEXPERIENCE)
Auto-Generate Drawings creates drawings from your CAD and automatically adds standard views, section views, dimensions, annotations, BOMs, and revision tables. It's not meant to complete your entire drawing, but it handles most of the setup work. This requires 3DEXPERIENCE access.
Aura is a conversational AI assistant that operates within your designs and data to provide SOLIDWORKS help, answer questions about internal documentation, and automate tasks. It's trained on SOLIDWORKS documentation and manuals. Aura launched in beta in July 2025 and requires 3DEXPERIENCE.
Image-to-Sketch uses computer vision to convert reference images or drawings to editable sketches for rapid concepting. Useful for early-stage design when you're working from napkin sketches or photos of competitor products.
What's Still in Development
SOLIDWORKS has demonstrated features like Generative Assembly (answering questions to automatically create assembled models) and Generative 3D Part (converting photos to 3D models) at conferences, but these aren't widely shipped yet. Engineers Rule coverage discusses these capabilities, but check release notes before assuming they're available in your version.
The Platform Reality
Here's something the marketing materials gloss over: many of SOLIDWORKS' most interesting AI features require the 3DEXPERIENCE platform.
If you're running desktop SOLIDWORKS without a 3DEXPERIENCE connection, your AI options are limited to the locally-running features like Fastener Recognition, Command Predictor, Selection Helper, and Smart Tools. These are useful, but they're not the headline features from conference keynotes.
Auto-Generate Drawings and Aura both require cloud access through 3DEXPERIENCE. GoEngineer's analysis notes that generative AI tools are more computationally intensive because they create content rather than just analyze data, which is why they run in the cloud.
For teams with ITAR compliance requirements or strict data security policies, the distinction between local and cloud-based tools matters.
Topology Optimization: The Original "Generative Design"
Before the current AI wave, SOLIDWORKS already had topology optimization through its Simulation add-in. This isn't new, but it's worth understanding because it's the most mature "generative" capability in the platform.
Topology Study in SOLIDWORKS Simulation Professional and Premium uses algorithms to remove unnecessary material from a design while maintaining structural integrity. You define the design space, specify preserved regions, set material properties and loads, then run the solver to get an optimized shape.
This is useful for lightweight brackets, structural components, and any part where material reduction matters. Aerospace and automotive teams use it regularly. But it's simulation-driven optimization, not AI in the current sense. You still need to know how to set up the study correctly.
Comparison: AI Tools for SOLIDWORKS Users
Here's an honest comparison of AI options available to SOLIDWORKS users today. Each tool serves different purposes, so the "best" choice depends on your specific pain points.
Capability | Leo AI | SOLIDWORKS Native AI | Aura | Design Assistant |
Availability | Production (60,000+ users) | Production (2025+) | Beta (July 2025) | Production (Cloud only) |
Platform Requirements | CAD-agnostic (works with SOLIDWORKS, Onshape, and other CAD tools) | SOLIDWORKS 2025+ | 3DEXPERIENCE required | SOLIDWORKS Cloud only |
Technical Q&A | Yes (1M+ sources, cited answers) | No | Limited (SOLIDWORKS docs only) | No |
Part Search | Yes (PLM + 120M vendor parts) | No | No | No |

Desktop SOLIDWORKS Support | Yes | Yes | No (3DEXPERIENCE only) | No (Cloud only) |
Key Takeaways from the Comparison
Native SOLIDWORKS AI excels at in-CAD automation: faster fastener insertion, smarter selections, drawing setup. These features reduce clicks and speed up modeling tasks you're already doing. The limitation is they don't help with decisions that happen outside the modeling environment.
Aura is promising for teams already on 3DEXPERIENCE. It understands SOLIDWORKS documentation and can answer questions about features and workflows. But it's beta, requires platform migration, and doesn't access external engineering knowledge or your PLM data.
Design Assistant offers useful ML-powered suggestions but only works in SOLIDWORKS Cloud (browser-based). If you're on desktop SOLIDWORKS, it's not available.
Leo AI addresses the gaps that native tools don't cover: technical Q&A with verified sources, part search across your PLM and vendor catalogs, engineering calculations, and concept visualization. Because it's CAD-agnostic, it works across different tools and doesn't lock you into a specific platform. The trade-off is it doesn't automate in-CAD tasks like fastener insertion or command prediction.

Which Tool for Which Problem?
If your bottleneck is: repetitive fastener insertion, edge selection, or drawing setup Use: Native SOLIDWORKS AI features
If your bottleneck is: finding answers to technical questions, searching for existing parts, or running calculations Use: Leo AI
If your bottleneck is: learning SOLIDWORKS features or navigating documentation Use: Aura (if you're on 3DEXPERIENCE) or Leo AI (if you're not)
If your bottleneck is: repetitive selection patterns in browser-based CAD Use: Design Assistant (SOLIDWORKS Cloud only)
The practical approach for most teams: use native SOLIDWORKS AI for modeling automation, and a purpose-built engineering copilot like Leo AI for knowledge retrieval and decision support.
What About Third-Party AI Copilots?
Native SOLIDWORKS AI features focus on automating tasks within the modeling environment. They don't help with technical Q&A, part search across your PLM, engineering calculations, or design documentation.
That's where third-party copilots like Leo AI come in. Leo integrates with SOLIDWORKS through a dedicated add-in and connects to SOLIDWORKS PDM. It's designed to complement native features with capabilities that Dassault isn't building:
Technical Q&A with answers sourced from 1M+ engineering references
Part search across your PLM system and 120M+ vendor parts
Engineering calculations with cited sources
3D mesh concept generation for rapid visualization
Design inspection against best practices
Leo is SOC 2 certified with zero training on customer data, which addresses the security concerns that make some teams hesitant about cloud-based AI tools. The platform has 60,000+ users at companies including HP, Scania, Intel, and Mobileye.
The combination makes sense: use SOLIDWORKS native AI for in-CAD automation (fastener recognition, command prediction, drawing generation) and a purpose-built engineering copilot for knowledge retrieval, part search, and decision support.
Practical Adoption Path for Engineering Teams
Step 1: Assess What You Already Have
Before buying anything new, check what's already included with your SOLIDWORKS license:
Fastener Recognition, Command Predictor, and Selection Helper are available in SOLIDWORKS 2025+
Smart Tools have been available for years
Topology Study requires Simulation Professional or Premium
Auto-Generate Drawings and Aura require 3DEXPERIENCE
If you're on an older SOLIDWORKS version, the upgrade cost may be justified by the AI features alone.
Step 2: Run a Focused Pilot
Pick one workflow where AI can deliver measurable improvement. Fastener insertion is a good candidate because it's easy to measure (time per assembly) and the feature is mature.
Track before-and-after metrics:
Time to complete the task
Error rate (incorrect mates, missing hardware)
User satisfaction
Don't try to roll out everything at once. Each feature has a learning curve, and your team needs time to develop trust in the AI suggestions.
Step 3: Address the 3DEXPERIENCE Question
If the beta features (Auto-Generate Drawings, Aura) look valuable, you'll need to decide whether 3DEXPERIENCE migration makes sense for your organization. This is a bigger decision than just "do we want AI features" because it affects your entire CAD/PDM infrastructure.
For teams not ready for that transition, third-party copilots like Leo AI provide AI capabilities without requiring platform changes.
Step 4: Build Skills and Support
AI tools don't eliminate the need for CAD expertise. They shift it. Your team needs to understand:
When to trust AI suggestions vs. verify manually
How to phrase queries effectively (for conversational tools like Aura or Leo)
What the AI can and can't do
Designate power users who learn the tools deeply and can support colleagues. Create documentation for common workflows. Build feedback channels so issues get reported and addressed.
Security Considerations
Engineering data is sensitive. Before connecting any AI tool to your CAD environment or PDM:
For native SOLIDWORKS AI: Understand which features run locally vs. in the cloud. Fastener Recognition and Command Predictor run locally. Auto-Generate Drawings and Aura require 3DEXPERIENCE cloud access.
For third-party tools: Verify security certifications (SOC 2, GDPR compliance), data handling policies (is your data used for training?), and deployment options (can you run on-premises if required?).
General principles:
Enforce role-based access control
Separate customer/IP data from any model training pipelines
Log and audit AI decisions and data flows
Run security reviews before production deployment
Realistic Expectations
AI in CAD is useful but not transformative yet. Here's what you should realistically expect:
Immediate wins: Fastener insertion speed, reduced clicks on repetitive selection tasks, faster drawing setup.
Medium-term value: Better command discovery (especially for newer users), faster onboarding with conversational assistants, improved part reuse through intelligent search.
Not yet ready: Fully autonomous design generation, AI that understands complex engineering constraints without human oversight, replacement of engineering judgment.
The marketing claims about "65% weight reduction" and "80% development time savings" come from specific use cases (typically topology optimization in aerospace applications) and shouldn't be treated as typical outcomes.
What's Coming Next
Expect continued investment in:
Multi-modal AI that understands text, sketches, and 3D geometry together
Deeper integration between CAD, PLM, ERP, and MES systems
More autonomous assistants that can execute multi-step tasks under human oversight
The CAD vendors (Dassault, Autodesk, PTC, Siemens) are all racing to add AI capabilities. Competition is good for users because it drives feature development and keeps pricing reasonable.
For now, the practical approach is to adopt mature features (like Fastener Recognition), evaluate beta features carefully, and supplement with purpose-built tools (like Leo AI) for capabilities that native features don't address.
