SolidWorks is a solid modeling computer-aided design (CAD) software program running on Windows. It’s well-known and widely used for engineering and design, among the many other fields requiring 3D CAD software platforms.

Originally created in December 1993 by M.I.T. graduate Jon Hirschtick, SolidWorks is now a globally-recognized CAD software, first published by Dassault Systèmes in 1997 after acquiring the company for $310 million in stock and keeping Hirschtick on in a variety of roles for the next 14 years.

SolidWorks uses the same parametric feature-based approach to solid modeling originally developed by PTC for the ProEngineer/Creo CAD software systems, where parameters relate to constraints and values determine the shape or geometry of the model or assembly.

The SolidWorks Standard system requires a permanent license purchase of $3,995 and an ongoing annual subscription of $1,295, with a 30-day trial available as well as discounts for educational use. Online features available through SolidWorks include a forum, a CAD library of parts (3D Content Central), as well as support from resellers in the form of tutorials and courses in simulation, surfacing, and other areas important to successful component and assembly design.

Despite being an extremely useful and popular tool, certain aspects of the SolidWorks suite simply do not appeal to some, the cost being foremost among them. That’s where this article comes in. Join as as we dive into some of the best SolidWorks alternatives!


SolidWorks Alternatives Selection Criteria

Note that, when searching for alternative CAD software, it is important to keep your specific needs in mind. There is no point paying for software that has a USP of power surfacing when you’ll never use it! We’ve picked out a few key criteria for selecting a SolidWorks alternative:

  • Price: Is the software cheaper or more expensive? Does the pricing structure allow for a greater number of users at a cheaper cost?
  • User-friendliness: Is it easy to create simple geometry and solid models?
  • Capability: Are there more or fewer tools on offer than SolidWorks? Are there specific tools for functions like surfacing, welding, sheet metal, or injection molding?
  • Support: Is there a good online community and access to videos and tutorials?
  • Compatibility: Can SolidWorks files (as well as files from other modeling software) be opened and imported?
  • Operating systems (OS): Can the software be used on Microsoft Windows only or is it available on multiple platforms?
  • Trial period: Is there a trial period available to get used to the software?

In addition to addressing the above points, it is important to realize that many of the following alternatives will fundamentally differ from SolidWorks based on the intended focuses of their design.
