SolidWorks
by Dassault Systèmes
The most popular 3D CAD system for mechanical product design and manufacturing.
What is SolidWorks?
SolidWorks is the world's most installed mid-range 3D mechanical CAD system. Used by hundreds of thousands of manufacturers and product designers, its feature-based parametric modelling, assembly mates, and drawing generation have set the usability benchmark for desktop CAD. It is the daily driver for small and mid-sized manufacturers worldwide and retains huge presence in industrial machinery, automotive tier-suppliers, consumer product design, and educational institutions.
Beyond core modelling, SolidWorks offers Simulation (FEA), Flow Simulation (CFD), Plastics (mould flow), Electrical (schematics and cabling), PDM (product data management), and Composer (technical documentation). That coverage lets a small product-design firm run a complete product development pipeline — from concept to detail drawings to validation to manufacturing handoff — within one vendor environment.
For engineers, SolidWorks is often the first "real" 3D CAD they learn. It is a strong career foundation, but the modern mechanical design job market increasingly expects at least passing familiarity with its higher-end siblings (CATIA, NX) for automotive and aerospace OEMs, as well as cloud-based CAD (Onshape, Fusion 360) for startups. Still, SolidWorks proficiency opens more mechanical design doors than any other CAD tool globally.
Why engineers learn SolidWorks
- Widest 3D mechanical CAD install base outside automotive/aerospace OEMs.
- Certification exams (CSWA, CSWP, CSWE) give verifiable, recruiter-friendly credentials.
- Learning curve is friendlier than CATIA or NX — fast path to portfolio-ready skills.
- Strong community, rich YouTube and MySolidWorks learning ecosystem.
- Solid bridge into SolidWorks Simulation for entry-level FEA exposure.
Core capabilities
- Part modelling with feature tree, sketches, and parametric relations
- Assembly design with mates, configurations, and exploded views
- Production drawings with GD&T, BOM, and detailing standards
- Sheet metal, weldments, surfaces, and mould tooling
- SolidWorks Simulation: linear static, thermal, frequency, non-linear
- Flow Simulation for internal/external CFD
- Electrical schematic and 3D cable routing
- PDM Vault for file management and revision control
Typical workflow
- Capture design intent with sketches and features for each part.
- Assemble parts with mates; create sub-assemblies for clarity.
- Validate fit and motion; run clearance and interference checks.
- Run Simulation studies for critical load cases.
- Produce detail drawings with dimensions, tolerances, BOM.
- Release to PDM; generate exchange formats (STEP, IGES, DXF) for vendors.

Frequently asked questions
SolidWorks vs CATIA vs NX?
SolidWorks for small/medium manufacturers; CATIA for aerospace and automotive OEMs; NX for complex aerospace, defence, and high-end automotive. SolidWorks is the widest-mobility starting point.
Is CSWA worth it?
Yes, as an entry signal. CSWP is the more meaningful hiring filter. CSWE separates senior specialists.
Is SolidWorks still relevant with Onshape and Fusion 360?
Yes — enterprise adoption of cloud CAD is growing but gradual. SolidWorks dominates its segment and will for years to come.
Real questions, real answers
Less polished, more honest — the kind of questions engineers actually ask over coffee.
I learnt SolidWorks two years ago in college. Did I waste my time?
No, but you'll need to update what you know. The fundamentals (sketches, features, mates) haven't changed, but the workflows around PDM, simulation, and cloud collaboration have. Spend a weekend on a refresher and you're current again.
Should I take CSWA or just build a portfolio?
Do both, but the portfolio gets the job. CSWA is a 30-minute exam that confirms you know the basics — useful for your résumé filter, useless in an interview. The portfolio is what convinces a hiring manager you can ship parts.
I keep building things in SolidWorks that look good but won't manufacture. How do I fix this?
Spend a day with a machinist or sheet-metal fabricator. Watch them try to build something you designed. You'll learn more about DFM in three hours than three months of CAD videos. Every senior designer has had this exact wake-up call.
Is mechanical design dying because of automation and outsourcing?
The commodity drafting work, yes. The design-thinking work — figuring out what to build and how it should fit together — is more in demand than ever. Move up the value chain: simulation, design-for-manufacture, mechatronics. That's where the careers are.
