<il> I need help ://
<il> What would be the easiest way to exted the holes straight down?
<il> The way I started going about it is not simple at all hah
<freem> what means exted?
<il> extend*
<il> I want the holes to be slits with those cirles at their end
<freem> I would do an extrusion
<il> From the 'front' edge towards the circle?
<freem> what means slits?
<freem> sorry, I'm not english native :)
<il> Let me draw on the pic, it'll be clearer
<freem> sure
<il> No worries, you're trying to help me, I appreciate that :D
<freem> similarly, I'll try to help, I'm not a mechanics as well
<freem> failing to help others is a good way to learn
<freem> being successfull is one way to know you improved
<freem> so sharing knowledge is important to me
<freem> I'm not efficient at it though
<il> quick sketch of what I want to do, but don't know what would be the neatest way to do it https://0x0.st/XFpR.png
<freem> so you want to translage those circles down?
<freem> translate ffs
<il> yeah, I want to extend the holes straight down towards the front edge, so I have slits
<freem> ah, to extend, not translate
<il> But I want to keep everything orthogonal (not wonky, like in my sketch)
<freem> what about doing 2 arc-circles linked by 2 segments?
<freem> this, for each, ofc
<il> That would give me a pill shape, right?
<freem> that is what I thought you wanted?
<freem> but yes
<il> no, I want the hole to touch the bottom edge, and the bottom edge to be interrupted
<il> I want the shape to be like a comb lol
<il> I don't know how better to explain it
<il> But I want to keep the distances as they are right now
<il> let me try constraining it with angles...
<freem> had to find what "comb" means
<freem> ok
<freem> so, I'd do something like
<il> Your vocabulary is very acamedic heh
<freem> no
<il> academic*
<il> You know what translate means, but not comb :)
<freem> I'm just not a native english user
<freem> I'm french
<il> Oh, is it the same in french?
<freem> no
<il> xD
<freem> but I have a decent skill level in english
<freem> others also got confused when I said it's not my mothertongue, on IRC
<il> I'm not a native speaker as well, the difficulty in explaining this is because of it's technicality, not just language proficiency
<il> s/as well/either
<freem> but if your heard me real life you'd knew :D
<freem> I'm also a programmer
<freem> helps with some tech stuff... and likely with academics
<il> God damn... I don't know how to do this and it annoys me
<freem> well
<freem> what about
<freem> you draw an arc-circle, 45°, then a segment down, then an arc-circle 45°
<freem> the other direction
<freem> and repeat that, say, 3 or 4 times?
<freem> you'd have a "comb" right?
<il> I don't think we're understanding each other haha
<freem> that is possible
<freem> that is one of the things "comb" gave me
<freem> and the one which is the most on topic...
<il> Yes
<freem> so my proposal would work
<il> I used that example to explain what I meant by saying I want the holes to extend all the way to the front edge
<il> The shape is solid, the circles are holes
<freem> yeah, ok
<il> I want the hole to go to the front edge, and there to be no front edge where he hole meets it
<il> I get a toothed shape (reminiscent of a comb)
<il> That's what I want
<il> I don't understand how a 45 degree arc would help me with that
<freem> so you want the holes to *not* have their inherent botom part
<freem> because I had the wrong idea
<freem> you basically only need a simpler construct here
<il> There are no arcs in what I want to do, unless you count the remaining shape on top as a 180 degree arc (half circle as the ending of the slot)
<freem> a 90° arc circle with a segment
<freem> no arc?
<freem> why the circles then?
<il> imagine a bullet shape
<il> A rectangle with an arc on top
<il> That's what I want my holes to be
<il> I'm retarded
<freem> that's how I do my arcs as well
<il> I just realized I can align rectangles with the circles I have...
<freem> I basically draw rectangles, and stick an arc on them after
<freem> oh
<freem> well, sorry I have not helped then, I guess :)
<il> This is what happens when you do CAD at 11pm after work lol
<freem> and sorry for the stupid feeling, got it more than I would admit
<il> No, you helped, you got me thinking creatively, I'd have given up otherwise and left it for another day
<il> Naw, don't say sorry
<freem> huh, there are other moments to do CAD?
<il> hahaha
<il> One day, I'll have a completely free day (myth)
<freem> as for helping, I am one of the weird ones who think it's more helping to question the questionner, than to give the answer
<freem> basically, when I have a question, I try to ask more accurate versions of it
<freem> it's a hard process, in which both asker and askee tend to learn
<freem> but I like it
<freem> it's especially nice when you are trying to learn more
<freem> if you only answer to things you know, you can hardly improve
<freem> but if you put your nose in stuff you are not expert of, you can both teach and learn
<il> Yes
<il> I realized I can start with the rectangles instead of circles
<il> Even though it's not the more intuitive approach for me, it's easier to keep constraints this way
<freem> yes, you need to acquire a new paradigm to use solvespace
<freem> it is a very logical way to do things, but not math-driven
<il> I got the shape, but there's a problem
<il> There's no easy way for me to round the front edge of the cuts I made
<il> Like the corners ot he outside are rounded
<il> Which I could do if I did it all in the first sketch, before the first extrusion
<il> Let me try one more appreach before I give up
<il> I'll first save how far I got with this haha
<freem> I told you one already
<freem> draw half-teeth
<freem> which are: arc-circle 45°, segment, arc-circle 45° again
<freem> duplicate them, rotate half of them
<il> it's arc circle 90 degrees, segment, arc circle 90 degrees
<il> I understand now
<freem> those bulk operations are not doable AFAIK, but manually it's easy
<freem> might work with 90° as well
<il> If I'm understanding anything right
<freem> I think you are
<freem> I just went a bit further
<il> Let me try the psycho approach first (make a random shape with enough points and then constrain it to look what I want lol)
<freem> that's what I do usually :)
<il> Yeah, I think it might actually be the easiest way
<freem> it's just about using constraints to do the work
<freem> computers are our slaves, they are litterally made for that
<ghane> didnt follow the whole problem but draw the full shape of two half-width fins/legs with the slot, then repeat-translate it, and add rounded external corners afterwards either by an extra extrusion on each side or difference...
<freem> would work as well
<il> god damn, getting 0 DOF is so fucking satisfying lol https://0x0.st/XFfp.png
<il> It's like a puzzle video game, only IRL
<il> ghane: I understood it later, but I think this is more elegan hehe
<il> bonus points to whoever figures out what the model is supposed to be used for heh
<ghane> no idea
<ghane> was thinking filament guide for AMS, but the dimensions does not make sense
<ghane> il: is it your mousecords?
<il> heh, naw
<il> btw, what's the difference between extrusion assemble and union?
<ghane> im guessing that assemble will become two solids while union ends up being one?
<ghane> no idea what practical difference it makes
<freem> usually, union gives less conflicts, but I don't know the inner details
<ghane> assemble is quite recent addition iirc?
<ghane> dont think i ever used it actually
<il> ghane: good guess. I don't know what 'assembly' means in this ligno, so it's hard for me to interpret
<ghane> assemble is not mentionied in the ref.pl either
<il> Assembly is, though
<il> Time to slice this stl up heh
<il> The vertical laptop stand is amazing, I love it haha
<il> 3d printer is already improving my life in tiny little ways
<freem> <ghane> assemble is quite recent addition iirc?
<freem> It's around since few years, I always seen solvespace with it
<ghane> il: there is link file / assembly as well where you can draw individual parts separately and assemble them together into one drawing
<freem> I believe 3D printers will be important equipment in all houses in few decades
<ghane> time to say good night
<ghane> later
<il> freem: depending on how the computer literacy continues... improving or getting worse
<il> ghane: tc :D
<freem> no, it's agnostic to that
<freem> computer understanding is irrelevant to use a software
<il> I don't know how you can think that
<freem> 3D printers will be as frequent in houses as are various mechanics keys or egoine saws
<il> You have to at least understand the abstractions, if not the complexity that the abstractions hide
<freem> sure
<freem> but that is unrelated to computers
<il> Most people today don't understand the computer abstractions, even
<il> A file system
<freem> yes, the computer generation regressed on this compared to mine lol
<freem> but mechanics are mechanics
<freem> and CAD is about mechanics, not computers
<il> Yeah, so I don't know if I'll expect people in 20 years to be better with computers than us
<freem> and many people have mechanics tools in their house
<il> I don't know if CAD is about mechanics
<freem> better with computers? no
<freem> they'll be worst
<il> I think it's about computer aided design heh
<freem> computer *aided* yes
<il> You can't be much aided if you don't know how to use a computer
<freem> computer, or rather software, is a tool to assist a paradigm
<freem> nothing less, nothing more
<freem> <il> You can't be much aided if you don't know how to use a computer
<freem> From my developper experience, it's a rather short-sighted vision
<freem> no offense meant, really
<freem> but users are often much smarter than IT people suspects
<freem> we, IT people, are quite arrogant
<il> I don't know, I work with people who work with computers, and I'm not impressed haha
<freem> I have been impressed by those, only after I learned how to use computers
<il> It's not just about intelligence, it's about curiosity and the drive to optimize. Most people are fine figuring out one way to do stuff and then sticking with it. I don't know if it's 'the engineer mindset' or whatever, but I don't stop at that
<freem> they are notably quite good at dodging security measures IT people put in place :D
<il> heh, security is always a tradeoff between convenience and security
<il> Most people like comfort and convenience, so it's an uphill battle lol
<freem> yeah
<il> That's why sticky notes with passwords are in every office
<il> it's a bit funny, but it is what it is
<freem> and it's unrelated to IT
<il> I could 'hack' my entire company just because of this
<freem> this behavior can be seen with cars, or electric systems as well
<il> it's not even hacking, I would just have to remember the 5 passwords lol
<freem> I know i know
