The best alternative to SOLIDWORKS is FreeCAD, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 100 alternatives to SOLIDWORKS and 11 are so hopefully you can find a suitable replacement. Other interesting alternatives to SOLIDWORKS are Autodesk Fusion, SolveSpace, Siemens NX and PTC Creo.

AS far as I have tried, FreeCAD is the only FOSS alternative to Solidworks/Catia/PTC that has a funtional workflow. It is the best of a poor bunch.
