<p>The software I began with was <a href="https://www.tinkercad.com/" rel="nofollow noreferrer">Tinkercad</a>, it is a fully online solution that is <em>very</em> beginner friendly. The interface is trivial to use and there's a 15 minutes tutorial that guides you over everything the software has to offer to the common user.</p>

<p>Here is a screenshot of the interface and a part I made using the basic tools :
<a href="https://i.sstatic.net/DOr6M.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/DOr6M.jpg" alt="enter image description here"></a></p>

<p>It works the following way : you are provided with a dozen basic shapes (cube, sphere, etc...) and you create your model using boolean combinations of those shapes and translation, rotation and scaling. That's for the base.</p>

<p>Then there is a very large collection of more complex shapes provided by the community (screw, stairs, tree) that tend to be very useful to create specific things and a very important aspect is that those shape usually have some parameter you can adjust at the creation of the object (say the thickness of the trunk and the number of branches of your tree). </p>

<p>The last increment of complexity is that those community objects are actually made using JavaScript (with their own API, it's not related to openjscad) and you can create your own objects by using their <strong>interactive JavaScript interface</strong>. That's when your programming and mathematical knowledge will be required.</p>

<p>As a small PS note: my personal taste is, depending on the part I want to make, to use either Tinkercad, Freecad or Openscad</p>

Is that list ranked? Also, I wouldn't call Fusion360 "Industrial" especially if AutoCAD itself is "Professional"; Fusion is a subset of AutoCAD geared toward mechanical design of parts and assemblies. AutoCAD can do that too, but it's really geared toward macroengineering of buildings and industrial machinery, and as such there's a massive difference in the power inherent in AutoCAD vs Fusion.

<p>I've had good luck using <a href="https://www.microsoft.com/en-us/p/3d-builder/9wzdncrfj3t6" rel="nofollow noreferrer">MS 3D Builder</a>. Most of <a href="https://www.thingiverse.com/jcoehoorn/designs" rel="nofollow noreferrer">my thingiverse models</a> were designed with 3D Builder. Depending on your Windows and Office installations, <em>this program may already be on your computer</em>, but otherwise you install it via the Windows Store. This program may also make good use of your math skills; I've done more trigonometry getting dimensions right for my models than all other areas of my life combined.</p>

<p><a href="http://www.meshmixer.com/" rel="nofollow noreferrer">MeshMixer</a> is another good free option. It's significantly more powerful than 3D Builder and many other free options, but I've found it much harder to get comfortable using. The visualization, especially, just hasn't been as clean, often making sharp edges appear to be rounded on the screen. Still, and I know and desire the power it offers, and I'll occasionally open it up for specific things. If nothing else, it's good for measuring/verifying the thickness of a section, and sometimes I can use it to repair models botched by other programs.</p>

<p>Finally, I'll bring up <a href="https://www.openscad.org/" rel="nofollow noreferrer">OpenSCAD</a> again. OpenSCAD effectively lets you write a program to generate your models. As such, it's especially good when creating things you will want to do more than once, where you'll tweak or customize the initial part for later uses. One way you can achieve re-use like this is creating a library of partial-designs or raw shapes which you can then resize/stretch/etc and add or mix into other parts using the other programs. The other area where OpenSCAD really shines is in prototyping. When you discover just this one section of a part shoud have been a couple millimeters longer after the initial print, it's much easier to adjust this with OpenSCAD than with many of the other options.</p>

<p>OpenSCAD sounds like the best fit for the original poster given his math background but I think SketchUp is probably the easiest software for most beginners to use for basic part creation.</p>

<p>There are two (or three) plugins I would recommend for anyone looking to use it to produce STL
<a href="https://extensions.sketchup.com/en/content/sketchup-stl" rel="nofollow">https://extensions.sketchup.com/en/content/sketchup-stl</a>
<a href="https://extensions.sketchup.com/en/content/solid-inspector" rel="nofollow">https://extensions.sketchup.com/en/content/solid-inspector</a>
<a href="https://extensions.sketchup.com/en/content/solid-inspector%C2%B2" rel="nofollow">https://extensions.sketchup.com/en/content/solid-inspector%C2%B2</a></p>

<p>The first one allows export to STL
The second and third check models to ensure they're solid. This is important for 3D printing as slicers have issues when models have holes in them.</p>

<p>One more tool I would recommend to the beginner is
<a href="http://www.netfabb.com/basic.php" rel="nofollow">http://www.netfabb.com/basic.php</a></p>

<p>It also checks over STL files to ensure there won't be any problems slicing them.</p>

As the original poster referenced his interest and likely his skills in math, the OpenSCAD option is superior to SketchUp. I can think of no circumstances where a strong knowledge of formulae and mathematical processes would be implemented in SketchUp, unless one is creating a plug-in or a specialty script.

For beginners, I'd want more information from the prospective user.

<p>I would add OnShape.com to the list.  The only downside of a free account is that your designs are publicly viewable.</p>

<p>I would also add support for OpenSCAD.  It is my go-to program for difficult problems, especially where being able to script something is far more efficient that dozens of clicks and careful GUI actions.</p>

<p>I don't have a heavy math background, but enjoy using such skills when applicable.</p>

<p>If you've not yet explored <a href="http://www.openscad.org/" rel="nofollow noreferrer">OpenSCAD</a>, you may find that it meets your qualifications. It's more or less a scripting/descriptive language "compiler" that takes ordinary text and converts it to your model design. I use quotes, because I'm not skilled enough to qualify it as a true compiler, although it works in a similar manner and may indeed be a compiler.</p>

<p>It meets another qualification of yours in that it's free and there's quite a supportive mailing list/forum for any questions or difficulties that arise. If you look on Thingiverse using OpenSCAD as a search term, you'll find others' code available for examination and integration into your own models.</p>

<p>For the folks who are not so much into the math and text and logic, there's a GUI of sorts for OpenSCAD called <a href="https://www.blockscad3d.com/" rel="nofollow noreferrer">BlocksCAD</a> that allows drag and drop of various modules in a manner akin to Scratch programming. </p>

<p>I'd been using OpenSCAD long enough that I found BlocksCAD to overly complicate the creation of models by obscuring details. It may be better suited for younger model makers in that respect.</p>

<p>Syntax and punctuation errors would be eliminated with BlocksCAD, while it's far too easy to create such errors in the editor for OpenSCAD. One gets used to it and error count quickly is reduced.</p>

I concur re. OpenSCAD -- if you're not scared off by doing affine transformations and writing your own 'for' loops, it won't take long to learn. It *may* be more work at the outset (as compared with something where you drag shapes in a GUI), but as soon as you try to re-use part of a design (in the same or a different overall object), modify some feature without manually manipulating every related part, etc, you'll regain all that time and more.

I started making models in OpenSCAD using "brute force" assignments. Seeing someone else's work using parametric values has made my model creation that much easier.

As an example, my recent model measured out to a 20mm gap, printed to a 19mm gap and fits perfectly when I set the gap to 21.5, which changed all the other dimensions of the model related to that axis. Parametric assignments meant one number changed in the code and bingo!

For those interested in BlocksCAD: it's an open source software with [the code on Github](https://github.com/EinsteinsWorkshop/BlocksCAD). Not updated since April 2017, so it might not be the latest version found on [blockscad3d.com](https://www.blockscad3d.com/), though.

It meets another qualification of yours in that it's free and there's quite a supportive mailing list/forum for any questions or difficulties that arise. If you look on Thingiverse using OpenSCAD as a search term, you'll find others' code available for examination and integration into your own models.

For the folks who are not so much into the math and text and logic, there's a GUI of sorts for OpenSCAD called [BlocksCAD](https://www.blockscad3d.com/) that allows drag and drop of various modules in a manner akin to Scratch programming.

I'd been using OpenSCAD long enough that I found BlocksCAD to overly complicate the creation of models by obscuring details. It may be better suited for younger model makers in that respect.

Syntax and punctuation errors would be eliminated with BlocksCAD, while it's far too easy to create such errors in the editor for OpenSCAD. One gets used to it and error count quickly is reduced.

> **Comments:**
> **username_12**: I concur re. OpenSCAD -- if you're not scared off by doing affine transformations and writing your own 'for' loops, it won't take long to learn. It *may* be more work at the outset (as compared with something where you drag shapes in a GUI), but as soon as you try to re-use part of a design (in the same or a different overall object), modify some feature without manually manipulating every related part, etc, you'll regain all that time and more.  
> **username_10**: I started making models in OpenSCAD using "brute force" assignments. Seeing someone else's work using parametric values has made my model creation that much easier.  As an example, my recent model measured out to a 20mm gap, printed to a 19mm gap and fits perfectly when I set the gap to 21.5, which changed all the other dimensions of the model related to that axis. Parametric assignments meant one number changed in the code and bingo!  
> **username_13**: OpenScad Rules.  
> **username_14**: For those interested in BlocksCAD: it's an open source software with [the code on Github](https://github.com/EinsteinsWorkshop/BlocksCAD). Not updated since April 2017, so it might not be the latest version found on [blockscad3d.com](https://www.blockscad3d.com/), though.

The software I began with was [Tinkercad](https://www.tinkercad.com/), it is a fully online solution that is *very* beginner friendly. The interface is trivial to use and there's a 15 minutes tutorial that guides you over everything the software has to offer to the common user.

Here is a screenshot of the interface and a part I made using the basic tools :
[![enter image description here](https://i.sstatic.net/DOr6M.jpg)](https://i.sstatic.net/DOr6M.jpg)

It works the following way : you are provided with a dozen basic shapes (cube, sphere, etc...) and you create your model using boolean combinations of those shapes and translation, rotation and scaling. That's for the base.

Then there is a very large collection of more complex shapes provided by the community (screw, stairs, tree) that tend to be very useful to create specific things and a very important aspect is that those shape usually have some parameter you can adjust at the creation of the object (say the thickness of the trunk and the number of branches of your tree).

The last increment of complexity is that those community objects are actually made using JavaScript (with their own API, it's not related to openjscad) and you can create your own objects by using their **interactive JavaScript interface**. That's when your programming and mathematical knowledge will be required.

As a small PS note: my personal taste is, depending on the part I want to make, to use either Tinkercad, Freecad or Openscad

[Blender](https://www.blender.org) is a free professional level application, where maths isn't particularly necessary but can be used to good effect, and its *minimum* requirements aren't all that excessive (my copy of Blender runs on a maxed out 20 year old Dell 380):

### Minimum (basic usage) hardware

* 32-bit dual core 2 GHz CPU with SSE2 support.
* 2 GB RAM
* 24 bits 1280×768 display
* Mouse or trackpad
* OpenGL 2.1 compatible graphics with 512 MB RAM

### Recommended hardware

* 64-bit quad core CPU
* 8 GB RAM
* Full HD display with 24 bit colour
* Three button mouse
* OpenGL 3.2 compatible graphics with 2 GB RAM

### Optimal (production-grade) hardware

* 64-bit eight core CPU
* 16 GB RAM
* Two full HD displays with 24 bit colour
* Three button mouse and graphics tablet
* Dual OpenGL 3.2 compatible graphics cards with 4 GB RAM

If you like coding, then Python and C libraries are available as well.

Also, there is a [StackExchange site dedicated to Blender](https://blender.stackexchange.com), which is useful.

> **Comments:**
> **username_5**: Is that list ranked? Also, I wouldn't call Fusion360 "Industrial" especially if AutoCAD itself is "Professional"; Fusion is a subset of AutoCAD geared toward mechanical design of parts and assemblies. AutoCAD can do that too, but it's really geared toward macroengineering of buildings and industrial machinery, and as such there's a massive difference in the power inherent in AutoCAD vs Fusion.

I've had good luck using [MS 3D Builder](https://www.microsoft.com/en-us/p/3d-builder/9wzdncrfj3t6). Most of [my thingiverse models](https://www.thingiverse.com/jcoehoorn/designs) were designed with 3D Builder. Depending on your Windows and Office installations, *this program may already be on your computer*, but otherwise you install it via the Windows Store. This program may also make good use of your math skills; I've done more trigonometry getting dimensions right for my models than all other areas of my life combined.

[MeshMixer](http://www.meshmixer.com/) is another good free option. It's significantly more powerful than 3D Builder and many other free options, but I've found it much harder to get comfortable using. The visualization, especially, just hasn't been as clean, often making sharp edges appear to be rounded on the screen. Still, and I know and desire the power it offers, and I'll occasionally open it up for specific things. If nothing else, it's good for measuring/verifying the thickness of a section, and sometimes I can use it to repair models botched by other programs.

Finally, I'll bring up [OpenSCAD](https://www.openscad.org/) again. OpenSCAD effectively lets you write a program to generate your models. As such, it's especially good when creating things you will want to do more than once, where you'll tweak or customize the initial part for later uses. One way you can achieve re-use like this is creating a library of partial-designs or raw shapes which you can then resize/stretch/etc and add or mix into other parts using the other programs. The other area where OpenSCAD really shines is in prototyping. When you discover just this one section of a part shoud have been a couple millimeters longer after the initial print, it's much easier to adjust this with OpenSCAD than with many of the other options.

OpenSCAD sounds like the best fit for the original poster given his math background but I think SketchUp is probably the easiest software for most beginners to use for basic part creation.

There are two (or three) plugins I would recommend for anyone looking to use it to produce STL
<https://extensions.sketchup.com/en/content/sketchup-stl>
<https://extensions.sketchup.com/en/content/solid-inspector>
<https://extensions.sketchup.com/en/content/solid-inspector%C2%B2>

The first one allows export to STL
The second and third check models to ensure they're solid. This is important for 3D printing as slicers have issues when models have holes in them.

One more tool I would recommend to the beginner is
<http://www.netfabb.com/basic.php>

It also checks over STL files to ensure there won't be any problems slicing them.

> **Comments:**
> **username_10**: As the original poster referenced his interest and likely his skills in math, the OpenSCAD option is superior to SketchUp. I can think of no circumstances where a strong knowledge of formulae and mathematical processes would be implemented in SketchUp, unless one is creating a plug-in or a specialty script.  For beginners, I'd want more information from the prospective user.  
> **username_9**: You are restating exactly what I said in the first sentence of my answer. The purpose of my answer was to provide an alternative answer to the question of "Good (preferably free) beginner software for part creation" which inevitably will attract other beginner users who may not have a math background. If you don't like the answer you don't have to vote for it.

I would add OnShape.com to the list. The only downside of a free account is that your designs are publicly viewable.

I would also add support for OpenSCAD. It is my go-to program for difficult problems, especially where being able to script something is far more efficient that dozens of clicks and careful GUI actions.
