<petaflot> InPhase: just saw your message. I considered this, but my first guess is that it has to do with the dotSCAD lib ; the solids it generates (at least for my use case, that is a voronoized sphere) throws quite a few warnings and behaves very badly with boolean operations on other solids. also, I might have to cheat a little bit because there's a function in there that calulates points for a "random
<petaflot> pseudo-sphere" and using this as-is makes the trial-and-error-by-masking-method useless.

<J22> petaflot if you found an issue with dotSCAD you can open a ticket here https://github.com/JustinSDK/dotSCAD
<J22> a warning is already a sign that something is not  ok  and should not be ignored as it could lead to issues later (except you understand why the warning happens)

<retrosenator> back for more.. still trying to get offset to work in 3d
<Scopeuk> offset it 2d

<J22> retrosenator .. you can stack extruded 2D offsets
<J22> or it is minkowski
<retrosenator> that cant do negative
<retrosenator> another issue: negative objects
<retrosenator> i want to union a reinforced hole into the side of something
<retrosenator> the hole now has to be negative as it wont subtract from whatever it gets unioned to, so it needs to be negative but there is no way to make it
<Scopeuk> Union with a negative is conceptually what difference does
<retrosenator> its possible to do everything still sure
<retrosenator> its not convenient
<Scopeuk> I appreciate this means positive and negative space have to be tracked independently as something you add can't contain negative space to remove from the base offset
<retrosenator> I am talking about creating module hole(), that can be unioned to another object creating a hole in it
<retrosenator> negative and positive spaces have rules applied during union, difference intersect etc yes
<retrosenator> the hole would generally also have decoration around the hole (positive space)
<J22> in a difference every children >1 is treated as negative space
<J22> you also can make modules that make holes in children and add geometry
<retrosenator> by using children() directly you mean
<J22> children() is  a placeholder for an other object when used in a modul
<J22> but it is often easier to show what your result should look like - so we can help you how to archive ..  the approach  "i need a feature so i can use the software differently"  is  likely to fail
<J22> workflow!
<othx> workflow is https://xkcd.com/1172/
<J22> retrosenator https://bpa.st/RE7A  here the module Hole will make a hole in every object used as child .. and also add a ring

<retrosenator> but then you have to chain them
<retrosenator> to get many, and you cant translate them
snaked has joined #openscad
J22 has quit [Quit: Client closed]
J22 has joined #openscad
<J22> you sure can translate them ..  also make the module to do what you need  -  you can address children so the holes get children itself
<J22> i assume you are just not very familiar with CSG operations  ..
noonien has joined #openscad
<J22> you can add a loop so you define an array with coordinates and a hole will be placed at each position
<J22> retrosenator here https://bpa.st/WIPQ  ..
<J22> you could even do something like Hole(pos=[for([1:17])concat(rands(3,97,2),0) ])cube([100,100,5]);   // with that code
<J22> looks like  some one had fun https://pasteboard.co/QrDiZJopcGKI.png

<J22> hmm wonder why that image is only displayed if i open it in an extra tap
<teepee> no idea, original image provided by google
<teepee> ugh, it's an SVG with PNGs inside?
<teepee> yeah, chrome does not like it, works fine in firefox
<teepee> ok, so lets have one PNG instead of 3 PNGs inside SVG
<J22> on the GSoC page are svg with text that work ..  and png
<teepee> right
<teepee> if I don't push the changes to github, nothing happens on the website ;-)
<gbruno> [github] t-paul pushed 1 additions 2 modifications (Switch to PNG image.) https://github.com/openscad/openscad.github.com/commit/64ddf80915b5eda4c57dc7f08805527675973897
<teepee> much more interesting question... is the ticker working?
<J22> this rolling titelbar?
<J22> could be a little faster

<retrosenator> J22: its very cool and all.. but its a bit hard way to work with
<retrosenator> J22: a bunch of different ways to convert scripts into openscad I am studying.. I made one as well
<retrosenator> perhaps a new language can be more concise but also support a lot more operations
