If you are a product designer, mechanical engineer, or manufacturing professional evaluating parametric CAD packages, the comparison between Autodesk Inventor and SolidWorks (from Dassault Systèmes) is almost inevitable. These two applications have long been the dominant choices in mechanical design CAD, competing directly in the mid-market manufacturing space. Both are powerful, mature platforms — but they have distinct strengths, ecosystems, and workflows that make them better suited to different contexts.
This guide gives you a straightforward comparison to help you decide which tool fits your needs.
Market Position and Industry Adoption
SolidWorks has historically had a wider install base and is particularly prevalent in:
- Consumer product design and consumer electronics
- Medical device engineering
- Small to medium manufacturing businesses
- UK universities and further education (it is taught very widely)
Autodesk Inventor is stronger in:
- Discrete manufacturing and industrial machinery
- Organisations already using Autodesk software (AutoCAD, AutoCAD Electrical, Vault)
- Engineering consultancies working with mixed Autodesk/non-Autodesk tools
- Companies that also use plant design tools (AutoCAD Plant 3D, Navisworks)
Both tools have large, active user communities in the UK, and both are well-supported by training providers and resellers.
Interface and Usability
SolidWorks is frequently praised for its interface, which many users find more intuitive, particularly for those new to parametric CAD. The feature manager tree, property manager panels, and right-click context menus are well-designed, and the software provides generous visual feedback throughout the modelling process.
Inventor uses the Autodesk ribbon interface, which is familiar to anyone who has used AutoCAD or other Autodesk products. It is not as immediately intuitive as SolidWorks for complete newcomers, but users with an Autodesk background will feel at home quickly. Recent versions of Inventor have improved substantially in usability.
For teams already embedded in the Autodesk ecosystem, Inventor’s interface consistency is an advantage rather than a limitation.
Part Modelling Capabilities
Both packages offer comprehensive parametric solid modelling with sketch-based features (extrude, revolve, sweep, loft), direct editing tools, and surface modelling capabilities. At the core modelling level, neither has a decisive advantage — both can build the same parts with roughly equivalent effort.
Differences become apparent in specific areas:
- Sheet metal — SolidWorks has traditionally had a slight edge in sheet metal with very polished tools; Inventor’s sheet metal environment is comprehensive and industry-proven, particularly for UK manufacturing
- Direct modelling — Inventor’s AnyCAD functionality, which allows live-link to foreign CAD formats without conversion, is a significant advantage when working with SolidWorks, CATIA, or STEP files from external partners
- Plastic part design — SolidWorks has historically been stronger here; Inventor’s plastic part features have improved but SolidWorks remains the choice for consumer product designers focused on injection moulding
Assembly Design
Both tools support large assembly design with performance modes that reduce the computational overhead of loading every component fully. Inventor’s Level of Detail representations and Shrinkwrap functionality allow complex assemblies with thousands of parts to be handled on standard workstations.
SolidWorks uses Lightweight components and SpeedPak configurations for a similar purpose. In practice, both tools handle mid-sized assemblies (hundreds to low thousands of parts) well; for very large assemblies (tens of thousands of parts), both show limitations and engineers typically use PDM systems to manage sub-assemblies.
Simulation and Analysis
Inventor Professional includes Stress Analysis (FEA), Frame Analysis, and Dynamic Simulation tools — a solid set of analysis capabilities for the price point. The FEA environment is accessible and produces reliable results for typical mechanical engineering design checks.
SolidWorks Simulation is available as a premium add-in with a wider range of analysis types including fatigue, thermal, flow simulation, and non-linear analysis. For engineers who rely heavily on simulation, SolidWorks’ broader simulation ecosystem has an advantage. However, serious simulation work in either platform tends to migrate to dedicated FEA packages regardless.
Data Management and Integration
Inventor integrates directly with Autodesk Vault, the company’s PDM (Product Data Management) system, which is an excellent and widely used document management solution for engineering teams. Vault provides version control, check-in/check-out workflows, and lifecycle management for Inventor files.
SolidWorks integrates with SolidWorks PDM (formerly SolidWorks Enterprise PDM), which offers similar functionality and is mature and well-regarded.
If your organisation uses other Autodesk products — AutoCAD Electrical, AutoCAD P&ID, Navisworks, or Revit — Inventor fits more naturally into that ecosystem than SolidWorks does.
Cost Considerations
Both SolidWorks and Inventor carry significant full commercial subscription costs. However, GetRenewedTech offers Autodesk Inventor Professional 2026 at £39.99 — dramatically reducing the barrier to access for individual engineers, small businesses, and consultancies evaluating the software.
SolidWorks does not have an equivalent accessible pricing option at this level, which gives Inventor a significant practical advantage for budget-conscious buyers.
The Decision Framework
Choose Inventor if:
- You already use Autodesk software and want a consistent ecosystem
- You work with external partners who send AutoCAD-derived or mixed-format files
- You need strong integration with Vault for PDM
- Your budget is a key constraint
Choose SolidWorks if:
- You are designing consumer products, medical devices, or injection-moulded plastic parts
- Your team or clients are standardised on SolidWorks
- Advanced simulation is a core requirement
- You need the widest possible ecosystem of third-party add-ins
Either way, if you are evaluating Inventor, getting access at £39.99 from GetRenewedTech makes the practical evaluation risk-free. Build your first few parts, run an assembly, generate a drawing — and see for yourself whether it meets your practice’s needs.
