CAD Software for juniors
My 9 year old is very keen on Robot Wars and is keen to develop his skills in designing shapes in 3d. Are there any CAD software packages suitable for
budding engineers.
Regards, Jon

You can get student licenses for most of the popular packages, but something like Autodesk Inventor (which would otherwise be ideal) would probably be
a bit much for a 9-year old.
Standard response, therefore, would be SketchUp Make. It's not particularly well suited to mechanical engineering, but it's a very
easy-to-use introduction to 3D CAD if it's mainly shapes he's interested in.

I found Fusion 360 very easy to use

Is google sketch up a thing still? That used to be a really powerful 3d program and was free.

Its trimble sketchup now, google sold it. But still free and still a superb bit of software. Very intuitive UI and a great intro to cad.

Fusion 360 is outstanding, free for hobbyists, and loads on guides on YouTube on how to use it. Free license includes up to 4 axis CAM too.

I'd have to disagree respectfully. As a CAD user daily I tried to do an introduction to sketchup for a family member who needed it. I/we ended
up so infuriated by it that I fired up fusion 360 expecting it might overwhelm them, but they picked it up instantly. F360 is free, amazing and when
you end up using other proper CAD systems the crossover is instantaneous.

I tried sketchup but I just couldn’t achieve anything with it, maybe because the first CAD tools I used were autocad and solidworks at uni but it was
just so unintuitive to me, I know a lot of people do use it though.

It is very different to autocad that i use everyday, albeit in 2D. I started using it with a limited introduction from a colleague and picked up the
basics in an afternoon. With a few months of only occasional use i was producing pretty complex stuff to assist my 2d cad. (Complex stacked stairs,
steel arrangements, roof intersections etc.)

I was brought up on AutoCAD (from the relatively early days of Release 11) and Solidworks, too, but I didn't have any problem with Sketchup, so
I'm finding it a bit odd to hear from those who did. I always say I reckon I could teach a reasonably bright chimp to use it (I've managed
with teenage work experience kids, which amounts to the same thing). AutoCAD, on the other hand, takes years to learn to a truly fluent level
- it's an absolute monster of a program.
As Loggyboy says, there are some things (complex roof intersections being a prime example) that would really hurt my head to do in 3D AutoCAD,
but are a piece of cake in Sketchup. I use the 'Pro' version, and import/export between it and other programs in some cases to take
advantage of their various strengths and weaknesses. I say again that I don't consider it a tool for engineering design, though - it's
more suited to architectural design.
As with all CAD programs, Sketchup needs basic discipline to maintain the quality of the model. Once even the slightest errors start to creep in, the
whole thing becomes flaky very quickly on a complex design. Make components out of everything, to stop geometry merging, and get used to using
layers. If you think you have glitchy geometry on part of the model, fix it before moving on... it will come back to bite you at a later
stage.
If you do decide to try SketchUp, I found this guide useful. It includes a lot of
tricks and tips that maybe aren't completely intuitive.
With any of the main CAD programs, there are almost always YouTube tutorials to show you how to do specific things, though, if you get stuck.

There is also FreeCAD, which will work on most platforms. As its name suggests, it's also free. I used
it for a while in its early days, but found it too flaky at that time - I believe it has improved massively.
Nowadays I use OpenSCAD, but I wouldn't like to teach that to a youngster unless they've already had
some experience in programming. It's very powerful, but there's a steep learning curve.
Whatever you do, stay away from Blender. It would probably do everything that a child would want to do, but the
learning curve is horrendous; even managing the user interface can scare new users right off when you first open the software!

Young kids at school are using Tinkercad to make stuff through a 3D printer seems ok

 Yeah I started with Autocad R13, have used SW2008+, IDEAS, NX6+, Sketchup, Fusion 360 and On-shape. But primarily SW and NX6. I'd still
rather scoop my eyeballs out with a frozen spoon than teach someone how to do anything with Sketchup. Nowt as funny as folk!

10+ years ago I used AutoCAD 2D and Solid Edge 3D, both self taught and both worked well.
I've recently tried Trimble Sketchup (twice) and don't get on with it as well as I'd hoped. I guess my mind may have been harking
back to yesteryear and expecting something different. I tried it a second time on the basis of not wanting to be beaten and hearing others say it was
good. Sadly I still didn't gel with it at all. On balance it's free though so if you can get on with it then nothing much to lose!
