<InPhase> Lots of places offer free services for open source projects even if those services cost resources. In this case, validating a release is almost certainly an automated process taking very minimal resources, such that the per unit cost should be approximately free. So it makes no sense to even think about charging free open source software.
<J24k9> honestly apple (and MS)  should pay that the software is running on these OS
<J24k9> else they can use WASM

<buZz> is there a free foss backrub service around, InPhase? :) my project could use one
<buZz> can you give a apple app a negative price? where you pay them for installing it, and apple has to fork up 30%?

<hyperscott> Hi all, is there a recommend place to go for some assistance when using openscad?
<buZz> #openscad is a nice channel , on irc
<buZz> just ask ;)
<InPhase> Also, if you haven't seen it:
<InPhase> tutorial?
<othx> tutorial is The OpenSCAD tutorial is a great place to learn how to create designs in OpenSCAD, and can be found at: https://en.wikibooks.org/wiki/OpenSCAD_Tutorial
<J24k20> if you have a specific problem you can use
<J24k20> paste!
<othx> paste is https://bpa.st for .scad files and other text like long error reports, https://pasteboard.co/ or https://imgur.com/ for images
<hyperscott> thank you
<hyperscott> I didnt want to come in and flood the channel with a hey how do i do this :)
<hyperscott> ill check the tutorial again and see if im missing something. and will go check paste board ill likly be back though :)
<hyperscott> thank you
<buZz> othx: https://paste.nurd.space/ supposedly does both, but i've never managed to upload a image ;)
<InPhase> hyperscott: The paste items are for sharing your code and images of problems/successes.
<buZz> i tend to find that trying to verbalize what i wanted to design usually already aids my brain into answering my own questions :P
<InPhase> Logical first project, a 3D printable rubber duck.
<buZz> lol
<buZz> i ordered some bigtreetech hw , it usually ships with a rubberduck :)
<buZz> does opencad have all the OG solids? like stanford(); or utah();

<kintel> I almost signed up for the paid Apple thing, but apparently they cannot validate us based on owning openscad.org, so it would have to be signed by an invididual developer - not sure how that's supposed to make it more secure or trustworthy
<kintel> That, or having a registered company with OpenSCAD in the name, which is a bit more expensive than the $100 per year : /
<hyperscott> Agree buzz
<hyperscott> ill dump the code i have and then ask for opinions on it if that is ok
<buZz> kintel: depends on the nation, i bet
<buZz> some nations it might be a lot cheaper to incorporate
<kintel> yeah, and hope Apple recognizes that nation ;)
<buZz> hehe
<buZz> belize perhaps, or st kitts
<kintel> but yeah, having a dirt cheap legal entity would be nice. Some should do an Open Collective-style OSS incorporation service
<buZz> could be nice :) could also open floodgates of hell
<kintel> heh, yeah, the infinite shell company cheat
<kintel> or circular shell company hacl
<kintel> unfortunately, those optimization are only available to a certain class of cri^H^H^Hpeople
<buZz> all people are criminal if you can find the right laws

<hyperscott> https://bpa.st/CBGA - Aim is to create a bowl like shape with parametric configurable riffles horizontal to the base around the inside of the bowl face. number of riffle, angle, percentage of bowl face covered. like a gold pan really - https://imgur.com/a/x58Si7K. the riffles are the it that's got me scratching head so far. I've also tried to make
<hyperscott> them configurable as a single riffle covering a percentage of the bowl face. https://bpa.st/CJJA - this though I'm miss understanding what i am doing with the start_angle i think

<J24k20> hyperscott rotate_extrude is your friend here
<hyperscott> thanks j24k20
<hyperscott> i was trying that having issues with syntax i think ill take another crack
<J24k20> hyperscott have a look here (just need to replace the numbers with parameters)
<hyperscott> yer nice, thats perfect
<hyperscott> thank you
<hyperscott> ok ill go play with this and see how far i can take it appreciate your help
<J24k20> also using offset ±   like    offset(-2) offset(2)  will round concave corners in 2D
<J24k20> reverse for convex
<J24k20> and set  $fa=1; $fs=.5;

<hyperscott> thank you
<hyperscott> ok thats so much nicer.
<hyperscott> only other thing i want to do is pull in a texture into a section and maybe a picture into the base.
<hyperscott> Guessing you do a bit with openscad J24k20?
<hyperscott> i tried a few times and hit walls. glad i stuck my head in here
<hyperscott> J24k20 - https://bpa.st/NKEQ - Thank you again, have added some comments and move some parts around well keep adjusting. Really appreciate you taking the time to give feed back.
misterfish has joined #openscad
<J24k20> hyperscott  you can add a small cylinder(thick,d=10);  to cover the center dent from the offset rounding
<J24k20> in image can be added by using  surface()
<J24k20> cheatsheet!
<othx> cheatsheet is https://www.openscad.org/cheatsheet/ for the release version and https://www.openscad.org/cheatsheet/snapshot.html for the development snapshot versions
<J24k20> a texture need to be made using a loop and rotate so it will follow the wall  - you can't map a texture onto a surface in openSCAD
<J24k20> what kind of texture do you want?
<J24k20> you can see some  of my designs on https://www.printables.com/@Jack
<hyperscott> Will review surface() on cheat sheet thanks.
<hyperscott> Texture doesnt really matter at the moment as long as i work out how to difference the pattern into a section on the bowl that will work. even if its just a hatch patern or circles over lapping
<hyperscott> the plan will be to hopefully have paramater to change pattern slightly to test different ones for abit of fun.
<hyperscott> J24k20 your models on printables mate nice collection.

<J24k20> hyperscott here more crash course https://bpa.st/5WSQ
<hyperscott> interesting, so i could do similare with a hexegon and have it difference from the face potentially so as to emboss or cut into the pan shape
<J24k20> exactly - you can use a cylinder(5,d=5,$fn=6) or a sphere (d=5,$fn=6);
<J24k20> or a cone aka cylinder(5,d1=5,d2=8,$fn=6);
<J24k20> if you switch every 2nd row half up those hexagon will interlace
<hyperscott> interesting, looking at one of your 126muster.scad from printables that create scrathc pads(the rub over pads) these are really intersting
<J24k20> to make it even better make the first (near center) smaller than those on the outside
<J24k20> those scratch pads must be old - Ü
<J24k20> (where the filename didn't had a year)
<hyperscott> ah yer updated October 17, 2021

<gbruno> [github] ochafik synchronize pull request #5180 (Color support for 3D rendering + export to glTF, Collada, STEP, PLY, X3D) https://github.com/openscad/openscad/pull/5180
<J24k20> hyperscott  you use for(rot=[0:10]) let(step=12) rotate(rot*step) and in your  for (i=[0:dist:length-5]) translate([i + rot%2?dist/2:0   ,0]) sphere();
<J24k20> this will move them for every 2nd rotation step
<hyperscott> translate([i + rot%2?dist/2:0   ,0]) sphere(); %2? is that a type of escape key
<buZz> i think thats inverted-if syntax?
<buZz> if (rot%2) { dist/2 } else {0}
<buZz> kinda
<hyperscott> interesting

<buZz> tnx Scopeuk
<Scopeuk> the main difference from if is the result is in the same scope as the test rather than a child scope
<buZz> and ofcourse , % is modulus
<Scopeuk> indead
<buZz> that might be a unknown too, for hyperscott ?
