00:07 <Friithian> hmm, wwould it be a horrible idea to print o-rings out of TPC? And if not, how do I make a torus in openscad

00:09 <InPhase> O-rings you would usually want to be super water tight.

00:10 <InPhase> Or air tight, depending on purpose.

00:11 <InPhase> Friithian: Oh, but I remember a trick that would do that. You take your print, then pack it into fine sand. Then you bake it just above the melting temperature. :)

00:11 <InPhase> Except then you have to get the sand out of your o-ring...

00:11 <Friithian> this isn't an actual o-ring o-ring, it is a grip for the ifixit kit screwdriver

00:12 <Friithian> although I have wanted to do that

00:12 <InPhase> Oh, well then it's just a question of how it feels to your hand.

00:18 <Friithian> is it worth making a torus though

00:31 <Friithian> oh fuck why does openscad make a sound when it finishes rendering I just noticed that

00:36 <teepee> ding ding

00:37 <teepee> just switch it off then

00:37 <teepee> maybe it will be configurable at some point, so you can make it bark at you when ready ;-)

00:38 <Friithian> I just never knew it did that as I always used it on my laptop

00:44 <teepee> it's doing that for a while now, but with the slow release cycle, it's probably still just the latest release

00:44 <Friithian> oh fuck I already have a print on that printer I can't start another one

00:44 <Friithian> I've never once before used openscad with audio enabled

01:10 <JordanBrown> Friithian: As to how to make a torus: rotate_extrude(...) translate(...) circle(...).

01:17 <Friithian> it took me a hot sec but in my mild altered state I managed to get that… took very hot of a sec

01:18 <Friithian> but uh, the printer that has my TPC is already printing something so

01:33 <InPhase> Friithian: Now I know what you're talking about. :) https://guide-images.cdn.ifixit.com/igi/UbuQBWd52JDNELUJ.medium

01:35 <InPhase> Looks like a silly design for a screwdriver handle. I see why they changed that for the later versions.

01:38 <Friithian> yeah this is the OG design

01:39 <Friithian> honestly I don't use the o-rings that much if I need TORQUE I use the TORQUE bar

01:39 <Friithian> but I like the look

02:09 <joseph_> teepee InPhase: My solution for rendering cut faces as a different color now appears to work. It's here: https://github.com/jbinvnt/openscad/tree/show-cut-faces. This is a different branch than the one that I originally created a PR for. In retrospect, I should have made a single gsoc-2022 branch in my fork (where my own little feature branches would get progressively merged) and have a standing PR to openscad:master. We may have

02:09 <joseph_> decided on this at the beginning of the summer, but if so then I forgot before making the first PR. Should I delete #4305 and create a new one? I would replicate my comment attributing the source of the example shaders

02:14 <joseph_> You'll notice that the approach I followed is a bit different than what I originally outlined. It turned out that instead of creating a fully new function that accepts polyhedrons and produces the vertex attributes separately, it made more sense to add new data onto polysets and then I could reuse a greater portion of the existing code. Additionally, the CI tests are still failing because they use fastcsg, while my method

02:14 <joseph_> currently requires nef. I know that this isn't ideal long-term

08:17 <teepee> joseph_: maybe the easiest way is to just create that gsoc-2022 branch now and put the current combined state into that

08:18 <teepee> if you then create a PR from that branch you can handle the local branches and merge those into your gsoc-2022 branch to appear automatically in the PR too

12:48 <Friithian> oh did I remember to set these rings to be radius or diameter?

12:49 <Friithian> did I just pull an InPhase

13:07 <Scopeuk> do we need a #pragma circles_use_radius to trigger a warning if you use dia or vice vs :P

13:07 <Friithian> yes

13:07 <Friithian> #pragma warn_me_for_being_stupid

13:35 <Friithian> sigh… looking at the print it does see a bit too big

13:35 <Friithian> oh fuck yup I forgot a /2…

13:37 <Friithian> although this was me fucking up a rotate_extrude

13:46 <Scopeuk> take this diameter, using that as radius...

13:47 <Friithian> exactly

13:47 <Friithian> I used the oring's ID to move the circle I was about to rotate_extrude, so I got ID*2 as the actual ID on the model

14:06 <J1A8435> i am often including reference objects %  just to make sure i didn't miss anyting

14:07 <Friithian> ah but that would require thinking

14:07 <J1A8435> just knowing about the own stupidity

14:51 <Friithian> well that is a good working print, only took two tries

14:54 <Scopeuk> I have 3d tool free from https://www.3d-tool.com/en-update.htm (free viewer) to just look over model dimensions from the stl before a print on a new model

14:55 <Scopeuk> not opensource and windows only but it has a very nice interface for measuring/interegating a design

21:41 <tcurdt-> when I do an 2d export it creates some axis and the path to the file ... how I can I disable that?

21:52 <teepee> i have no idea what that means

21:56 <tcurdt-> teepee https://images4.imagebam.com/af/27/a2/MECAMME_o.png

22:04 <tcurdt-> clear now?

22:23 <teepee> ah, this is about PDF export. no there's currently no option

22:31 <tcurdt-> hmm. ok :-/

23:04 <InPhase> tcurdt-: pdfcrop is a handy tool.
