OpenSCAD Tutorial for Beginners - Model a Toy Brick

[@CraftyEnelrad]

Yes, people are still watching your videos. Thanks for the tutorial. I even took your lesson and created a 4 peg block using my new found knowledge. THANKS!

[@AntonyHart]

Thanks, learned OpenSCAD tonight thanks to your clear tuts!

[@mathcodeprint]

Well done!!!

[@codefossa]

Thank you so much for going over the basics. After this video I was able to go off and create pretty much anything that came to mind. I just needed to learn how to begin and this was perfect for that.

[@vadimemelin9068]

Thank you very much for such a deliberate tutorial on this marvelous technology!

[@freeelectron8261]

I really love your tuts. I'm thinking of getting OpenSCAD. I think this may have convinced me.

[@mathcodeprint]

I'm glad you enjoy them. I really liked making this particular tutorial. Have fun with OpenSCAD.

[@magnuswootton6181]

if you paramaterize it, you can have a whole lego set out of it. I think the lego company might go bankrupt. :(

Very nice video. This style of 3D CAD appeals to me since I have a drafting background followed by a software background. I could pick this up fairly quickly. I tend to think better in terms of numbers than in terms of dragging images around the screen to poorly defined locations. I didn't see "OPENSCAD" appear on the block because KZbin always plops a bunch of graphical links on top of the video image.

[@HendrieBosch]

I really like your video's. Thanks a lot for the effort.

[@TheRainHarvester]

I like the freecad constraint method of designing. I made a video on how to get gcode automatically after modifying the design. It really quickened my pipeline.

[@mathcodeprint]

That's sounds terrific I'm going to check it out. I also prefer FreeCAD , but as freecad has a pretty high learning curve. Programs are great for getting started in modelling.

[@deemdoubleu]

Awesome demo thanks

[@SiebeBosch]

Awesome! Thanks a bunch!

[@tombert512]

This video is great; purely in the interest of pedantry, I have a few notes. 1) You actually don't need to wrap the characters in an array/vector/list/whatever-they-call-it; you can index a string character by doing a regular index like "this"[0]. 2) I would probably make the legs and pegs on the top into separate modulers, parameterized on width. For the peg, I would also take in the character you want to print as an argument. Then your for loop logic is greatly simplified, and you get a bit more reuse as a result. That said, this video is still really helpful, thanks for making it!

[@mathcodeprint]

I call you remarks refinement :)

[@tombert512]

@@mathcodeprint Out of curiosity, since you seem to use OpenSCAD a lot more than I do, have you noticed any faster rendering times if you use basic compsci optimizations? e.g. avoiding touching elements n^2 time, or using a better data structure or something?

[@mathcodeprint]

I haven't noticed, but I he honest I haven't really payed attention. For final renders if complex designs I usually walk away. Otherwise I just reduce the facet count $fn=, for tolerable "rendering"

[@tombert512]

@@mathcodeprint Fair enough, my biggest blocker thus far (coming from a software world, not a drafting one) has been the fact that there doesn't appear to be any kind of dictionary data structure, so I've had to spoof mappings with big "if-chain" functions, which of course will be O(n) for string comparisons. I guess for anything complicated, I'll just kick off a render and then go grocery shopping.

[@EurekasFigMedia]

Brilliant tutorial !!! does anyone know the link to the block diagram in teachers pay teachers ?

[@mathcodeprint]

Yes, me, I'll add to description. Soz. also here: www.teacherspayteachers.com/Product/Reverse-Engineering-Measurement-Worksheet-3817868

[@novahost2010]

Adorei o seu vídeo!!! Parabéns pela explicação.

[@Power-Wiesel]

Good tutorial. Thx :)

[@feru7201]

Hello. Could you help me with which program to add a mouse or a keystroke as shown in your videos. Thank you for your help in advance.

[@mathcodeprint]

Sorry I missed this, I use keymon. it might be linux only.

[@YigalBZ]

Thanks for the video. The link to your github is missing. Also - how do you translate from the "units" to real world dimensions?

[@mathcodeprint]

I'll add the link, later today, sorry. So for units OpenSCAD is unit agnostic. In the case of the brick I built it considering 1 unit to be equal to 1 mm.

[@YigalBZ]

@@mathcodeprint At what stage is the translation done to physical unit? What if I want a unit to be a 1 meter? and Inch?

[@esd9058]

Thank you

[@vadimemelin9068]

The only note, I can leave is that string itself is an array, so assigning a variable like this: text("LEGO"[0]) Would print a letter 'L'

[@mathcodeprint]

Good info thanks !

[@3dadventures792]

Hey, neat toy brick! Definitely looks very trademark non-infringing! Totally have never seen one like that. :p thanks for the video!

[@mathcodeprint]

But mine is yellow with red letters, certainly that is different :)

[@JarppaGuru]

noice! i made it scriptable any size and chamfers brick(L=4,W=2,H=3); brick(L=2,W=4,H=3); would do exact same piece H=6 double height H=1 1/3 size remove tabs it would be flat piece turning it to be tecnic i could make 80% bricks xD

[@Rabianurguven]

OMG, coding and 3d modeling idk that wow

[@vadimemelin9068]

It's more than 3d modeling - It's cad This is literally engineering re-invented

[@lifehackertips]

omg this is horrible, i can't imagine doing all this to make something simple like a rectangle with cylinders on top

[@JarppaGuru]

this simple thing sells millions xD

[@lifehackertips]

@ no, I mean the coding. There’s much easier ways to create a cube with six cylinders on top.
