Free alternatives to SolidWorks
2 free programs that can replace SolidWorks, each pairing checked by Radar's AI reviewer or by Radar.
SolidWorks is a 3D computer-aided design program from Dassault Systèmes, used by mechanical engineers, product designers and machine shops to model parts, build assemblies and produce technical drawings. It runs on Windows and is sold under paid licences, often with add-ons for simulation and other tasks.
The main question is files. SolidWorks formats are proprietary, so other programs usually exchange geometry through neutral formats such as STEP or IGES, which keep the shape but often lose the feature history, constraints and some drawing details. Test a few of your real parts and assemblies, and check dimensions after import. Think about who you work with: suppliers, customers and colleagues may expect native files, so ask whether neutral files are enough for them. Parametric modelling habits, drawing standards, simulation add-ons and macros will all need review. Expect a real learning curve, since commands and workflows are organised differently, and keep access to your old files until the transition is complete.
