I’ve tried ZW3D. What I can say is it looks like NX. I’m familiar with it cause I use NX before. And it capable doing g3 continuity. As far as I know it has good price, permanent license, and maintenence skip (just skip maintenance and after years just pay 1 time maintenence fee you will get the latest version). It is not as good as Siemens NX, needs more fix/features here and there. But it has potential in the future.

But for hobbyist I’ll recomend Solid Edge, because it has no imitation besides for non-commercial use. This one is really powerfull if you can use sync tech mainly for prismatic modeling. And 2024 version has been launched, just wait it till community edition will be updated.

Creo I never touch it so can’t say about it. But I like the UI.

Inventor, I have tried but didn’t like it.
