Now that Fusion 360 is no longer free, what would be some good free softwares to replace Fusion 360 that have most of the Fusion 360 tools?

Still now the functions are reduced in the free version.

Either way what free alternatives are there to Fusion 360.

While it needs to be mentioned, it also must be admitted that OpenSCAD is not what anyone would call a conventional CAD system. It is a 'programmatic' system, where shapes are entered and manipulated by entering lines of code. The method appeals to some, and is highly efficient for some things, but is going to be totally obscure to most people. Totally free and open-source, and it is being actively, albeit slowly, developed. Simple to install on all platforms. OpenSCAD files for an object are simple text files. No limitations now or likely, ever.

A nose cone in just a few lines:
Code:
cylinder (d = 24, h = 12, $fn = 180); // shoulder hull () { // this command connects the following two shapes with a surface translate ([0, 0, 12]) cylinder (d = 25, h = 5,$fn = 180); // base section

Is this still good if you do not have the Apple Pencil?

It works without the pencil but you spend a lot of time zooming in and out to get at the feature you want to work on. The pencil is the way to go. BTW, I'm surprised at how quick and responsive Shapr3D is on an iPad. There's a free version but it's limited; the Pro version requires a subscription.

I've been looking for a reason to jump. I don't like that Fusion is cloud based, plus they can change and limit whatever they want when they want. Don't get me wrong, I am totally ok with that- it's their company, and they can do that, and don't "owe" anything to anyone by continuing to keep it free.
With that, FreeCAD is rough. It's probably the best option on the market for a true open source, parametric CAD package "like" Solidworks or Fusion. It's just not as intuitive. It is in active development, although slow. Given a blank document and an hour of time, I can accomplish much more in Fusion. Fusion is much easier to brainstorm and work out and change designs too. I think given some time, and more people jumping off Fusion could change that for FreeCAD though. I hope so.

I'll second OpenSCAD, but then again I'm a programmer by trade so it's second nature to me.

For Rocketry related items, it works great - most things are pretty much cylinders, and aren't very complex. However, if you're not used to reading code (especially reading it bottom to top), it can be a bit difficult to understand at first. And if you're picking up someone else's design who didn't put in any comments, good luck to you.

Thanks to all of you for responding with so many options.

Are there some good tutorials for newbies/ begginers, that start at the very basic level and build up to more complex work?

Been able to get into a workable level at fusion but without the tutorial would not have been able

Not a tutorial, but I've tried to explain what's going on as I develop an OpenSCAD Nike-Ajax model.

it is still free, just don't sell stuff

Thanks that's a perfect starting point, will endeavour to follow along appreciate you sharing the step by step and that it ends up with a rocket
