I use Solidworks at work a lot. I can’t afford my own seat of Solidworks. OnShape is basically Solidworks with better assemblies in a browser window. I like it for designing stuff on my chromebook, or from any computer where I have some time.
It’s free if you’re OK with making your designs public. Since I like to share my designs, I use the free plan. I believe that the paid one will let you keep your stuff secret.
