OpenSCAD Tutorial (Part 4): Hull and Minkowski Transforms & debugging

How to run OpenSCAD to create models suitable for 3D printing.
This part discusses the hull() and minkowski() transformations and some of the debugging operators that OpenSCAD provides for highlighting components in composite objects.

Just came across this tutorial. You have an awesome talent of clearly explaining things. Thanks John.

[@JohnsBasement]

You're welcome. Glad to help.

[@xDevoneyx]

You'are explanation is awesome. Having the second child move around the surface of the first is something that is totally intuitive to understand! Thanks a lot!

[@JohnsBasement]

You're very velcome!

[@xnadave]

Holy crap! What a great tool.

[@JohnsBasement]

I couldn't agree more!!
Sometimes algorithmically expressing a shape is just easier. (Of course, not always... But when it is, OpenScad is suprisingly easy.)

@@JohnsBasement I'm an engineer. Coding to make physical objects sort of feels like cheating. But, I'll take the win. Thanks for the video.

[@MichaelGarcia-cg9on]

Thanks for the video, very helpful. I also liked how you include how to use the #, % and ! characters, thanks.

[@JohnsBasement]

You are very welcome! Thanks for letting me know.

[@kilikopela83]

Thank you. Great explanation, great examples.

Glad to know I could help!

[@DEtchells]

An old video of yours, but a super-clear explanation; I've subscribed, gonna check out all your other stuff. Looks like you're my new go-to-guy for OpenSCAD tutorial info :-) Thanks!!

[@JohnsBasement]

Hey! Thanks! Glad to meet you.

[@guoqiaonz]

very clear, very good.

[@agnichatian]

Nice work.

[@magneticking4339]

Once again... Thanks...

[@andymouse]

This is all very useful regardless of the modeling software your using...cheers.

[@yokoharvey5119]

Hi, excellent explanation of these two useful functions. Just one observation... the default parameter for `sphere` is the radius, not the diameter.

[@JohnsBasement]

Thanks. Sorry for the mistake.

[@FinnOliver]

Thanks

[@johnwaddle7742]

That was pretty cool,but i don`t see more videos??

[@JohnsBasement]

Oops... It looks like I put in the wrong link to the playlist for this tutorial. Sorry about that. here is the right one: th-cam.com/video/dx06_gcdMck/w-d-xo.html

[@rachelwigell8221]

Anyone ever tell you you sound just like that dude who plays Lemony Snicket in the new Netflix Series of Unfortunate Events

[@JohnsBasement]

This would have to be the first. Is that a good thing?

[@sinitarium]

​@@JohnsBasement Hi John, I just discovered your channel trying to learn more about openscad hull and Minkowski to do fillet... Great video! I so happened to listen to half video with audio muted and when I turned audio on I was very pleased with your voice heh. I don't have a clue who Lemony Snicket (I don't watch Netflix) but I look forward to listening to more of your videos :-) Seriously, your delivery is superb. No hesitation, no annoying ehh or repeating the same word, perfect smooth tempo... Congrats!
