SW basic is still about 4K I believe and is a perpetual license. That's standard on Solidworks, although they are pushing the cloud based version HARD. I use the software professionally, so the upgrades are worthwhile. Even essential, in fact. Solidworks change to a new version every year that is not forwards compatible - to force users into buying the maintenance package. If you only make models for yourself, not an issue. Also - SW policy is to make you pay for missing subscription years - I think to a maximum of 3 - if you decide to up your version year less frequently than once a year. It's a bit punitive in my view and I think they'd do better by cutting the sub fee - I think they'd get more people and make more money. But like I say, they are pushing the cloud based version hard and I think ultimately will ditch the perpetual licenses all together. They already tried it but there was a huge backlash, but eventually they'll do it again. Maybe it's actually cheaper to go that route, but I hate all these cloud based applications.
