| 06:43.29 | brlcad | starseeker: very nice! |
| 06:44.10 | brlcad | MinuteElectron: if you didn't notice, the site went live a couple days ago |
| 06:44.28 | brlcad | (sans ldap at the moment, and with some style simplification as you may notice) |

| 14:52.54 | *** join/#brlcad norias (n=Evil@pool-72-65-215-127.pitbpa.east.verizon.net) | |
| 14:53.27 | brlcad | MinuteElectron: mostly because it still wasn't fully behaving properly on ie6 .. and to fix ie6 *reliably* made things worse for the compliant places |
| 14:54.56 | brlcad | MinuteElectron: plus the style just really is sitting stale with me the more I use it.. so less is more ;) |
| 14:56.02 | brlcad | so it can start to get populated and the style can be fixed later .. really just wanted to finally take it live (so people could see all your hard efforts) :) |
| 14:57.21 | brlcad | in the process of fixing ie6, I just dropped the footer and simplified the blocks down to what you see, later did the same for the iphone .. then I really started to like that even more for everywhere |
| 14:57.26 | brlcad | hello norias |
| 15:01.45 | norias | hi |
| 15:02.40 | norias | how are you doing, brlcad? |
| 15:02.50 | brlcad | pretty good, thanks |
| 15:03.33 | norias | are you one of the brlcad developers? |
| 15:03.41 | brlcad | nods |
| 15:03.46 | norias | nice work |
| 15:03.52 | brlcad | thanks |
| 15:04.01 | brlcad | are you interested in development? |
| 15:04.06 | norias | just grabbed it yesterday, i'm a machinist trying to learn CAD |
| 15:04.18 | norias | i used to... maybe a decade ago... |
| 15:04.28 | norias | develop minor pieces of software |
| 15:04.37 | norias | database stuff for small businesses |
| 15:04.42 | norias | doubt i could touch this stuff |
| 15:05.27 | brlcad | oh, don't hold yourself back -- there's lots of levels and areas of development for just about any skill level :) |
| 15:05.37 | brlcad | otherwise, glad to hear it |
| 15:05.38 | norias | right on :) |
| 15:06.16 | norias | figured i'd hang out in here and see what gets talked about |
| 15:06.25 | norias | seems like a good way to get a feel for the software |
| 15:07.39 | norias | in about 24 hours, the only thing i've noticed that i'd think would be cool |
| 15:07.48 | norias | but probably not useful to professional users |
| 15:08.07 | norias | would be the capability of importing the Sketchup model format |
| 15:15.28 | brlcad | yeah, that would be interesting to have |
| 15:15.53 | brlcad | there are a slew of converters on the hopeful "todo" list |
| 15:16.00 | norias | i bet |
| 15:16.08 | brlcad | but the hot item this year is a STEP converter, and that's a pretty big order |
| 15:16.28 | norias | yeah,from what i understand of that format |
| 15:16.32 | norias | it sounds rather big |
| 15:16.39 | norias | that's the OSI standard, right? |
| 15:16.40 | brlcad | adds sketchup to http://brlcad.org/~sean/ideas.html |
| 15:16.51 | brlcad | no, it's an ISO standard |
| 15:16.55 | norias | er. |
| 15:16.57 | brlcad | :) |
| 15:17.01 | norias | yeah, more coffee :) |
| 15:18.05 | norias | i'm playing with the DXF export right now |
| 15:19.01 | norias | it's nice that this is available for mac |
| 15:19.12 | norias | it kinda seems like mac is ignored when it comes to CAD |
| 15:19.13 | norias | of any sort |
| 15:21.26 | brlcad | yeah, I'm really hoping we can finally get native working here in the next couple months |
| 15:21.33 | brlcad | so it's not reliant upon x11 |
| 15:22.04 | brlcad | which will make it a lot easier to have it install into /Applications as well |
| 15:22.15 | norias | oh, hmm, that'd be neat |
| 15:22.29 | norias | i'm pretty unix-familiar so the current way doesn't really bother me at all |
| 15:22.36 | norias | but i can see where that'd be nice |
| 15:22.59 | brlcad | yeah, the idea would be maybe three icons -- one being MGED, another being Archer, and a third for a "BRL-CAD Terminal" |
| 15:23.06 | norias | sounds like a big project... or is the GUI pretty thin? |
| 15:23.20 | brlcad | it's fairly neatly abstracted |
| 15:23.36 | norias | i played around with OBJ-C on OS X |
| 15:23.41 | norias | seems like a really nice system |
| 15:23.54 | brlcad | mged and archer both go through Tk and AquaTk finally seems to be working now (it's been too buggy) |
| 15:24.09 | norias | oh, ok |
| 15:25.12 | brlcad | if we're accepted into the summer of code, things are going to be really busy this summer... |
| 15:25.33 | norias | the whole google deal? |
| 15:25.41 | brlcad | but we would hopefully get two or three really interested students working on some good stuff |
| 15:25.45 | brlcad | yeah |
| 15:26.03 | norias | yeah, that'd be really interesting |
| 15:26.16 | norias | i have a buddy who designs robots for a living |
| 15:26.19 | brlcad | orgs are announced tomorrow, so we'll know soon enough |
| 15:26.23 | norias | i'm getting tempted to toss him a link |
| 15:26.56 | norias | not really sure what sort of software he's using |
| 15:26.59 | brlcad | our biggest "problem" right now is that the main gui is .. expert friendly .. sufficiently efficient for those that are trained in it |
| 15:27.18 | norias | i can see that |
| 15:27.18 | brlcad | but really hard for new users to learn, very steep learning curve |
| 15:27.41 | norias | with a software suite that does so much though... |
| 15:27.42 | brlcad | that's something we've recognized for years, been working on fixing |
| 15:27.51 | brlcad | yeah, the power's mostly all there |
| 15:27.57 | norias | can you really expect to simplify it that much? |
| 15:28.08 | brlcad | not simplify, make it more friendly ;) |
| 15:28.39 | norias | friendly is good :) |
| 15:29.01 | brlcad | right now if you want to "figure out" how to do something you know it can do, you either end up needing to go through the volumes of documentation, asking an existing expert user (forums, mailing list, irc), or looking at the source code |
| 15:29.08 | norias | i think i'm trying to make this do things it's not designed to do... |
| 15:29.08 | brlcad | the app itself doesn't really help you |
| 15:29.32 | brlcad | it should |
| 15:29.42 | norias | i can see your point, which is something, is just something someone like me is willing to do |
| 15:29.46 | norias | but alot of others wouldn't |
| 15:29.49 | brlcad | it's designed to be a swiss army knife of tools for many many purposes :) |
| 15:30.46 | norias | oddly enough, my end goal is to design military-style rifles |
| 15:31.10 | norias | i became fascinated with their design during my short time in the National Guard |
| 15:31.30 | brlcad | cool |
| 15:31.52 | norias | almost makes sense to use a DoD program... :) |
| 15:33.01 | brlcad | yeah .. no money on usability, all on core features.. :) |
| 15:33.22 | brlcad | it's primarily since we've gone open source that usability has become a hot priority |
| 15:33.35 | norias | i can see that |
| 15:33.36 | brlcad | been an issue for years, but always falls under the radar |
| 15:33.44 | brlcad | s/radar/prioritization/ |
| 15:33.49 | norias | since there's in-house training, i'd assume |
| 15:33.53 | norias | for the internal users |
| 15:33.57 | brlcad | and in-house experts |
| 15:34.00 | norias | right |
| 15:34.19 | brlcad | if something isn't working right, you can walk over and talk to a core developer any time |
| 15:34.48 | brlcad | need a tweak that does X, you might get it today or be told of a workaround that's sufficient (or even better) |
| 15:36.24 | brlcad | with open source, though.. it's desirable to get more core devs from all over working on the project |
| 15:38.20 | norias | looking through your list of ideas... |
| 15:38.27 | norias | you want it to spit out g-code? |
| 15:39.27 | CIA-33 | BRL-CAD: 03brlcad * r30531 10/brlcad/trunk/include/raytrace.h: include common.h |
| 15:41.03 | brlcad | yes, that has been oft requested |
| 15:41.08 | CIA-33 | BRL-CAD: 03brlcad * r30532 10/brlcad/trunk/include/brep.h: minor cleanup investigating the C++ linkage failure seen on Fedora. |
| 15:41.44 | norias | g-code... seems like that'd take... a few steps |
| 15:41.55 | brlcad | certainly something doable, shouldn't be "too" hard really given we can fully sample any geometry |
| 15:42.38 | norias | hmmm, i write g-code on a daily basis |
| 15:42.47 | norias | and that seems.. like it'd be interesting... |
| 15:42.53 | brlcad | you'd have to define available drill bits, the limits of the cnc machine (how many axes, etc), material types .. and solve paths |
| 15:44.35 | norias | i know in theory it should work |
| 15:44.50 | norias | i'm just trying to envision how it'd play out in practice |
| 15:44.54 | brlcad | my thoughts were to use our ray-trace library, which can be used to sample geometry in any pattern desired and at any resolution to find out where there is and is not material |
| 15:45.09 | starseeker | raises eyebrows - wikileaks claims to have a diagram about an early atomic bomb design |
| 15:45.25 | brlcad | starseeker: saw that, pretty nifty |
| 15:45.44 | brlcad | would make a simple can model :) |
| 15:45.53 | brlcad | bunch of spheres and cylinders :) |
| 15:46.02 | starseeker | heh - if it really is leaked they might get a bit annoyed at us for doing that ;-) |
| 15:46.40 | starseeker | 'course, the basic designs have been pretty well known for a while now |
| 15:46.46 | brlcad | gahs at the need to install fedora just for a build failure |
| 15:46.52 | starseeker | ick |
| 15:46.58 | brlcad | anyone got fedora on hand? :) |
| 15:47.57 | starseeker | meh - that's a pretty simple diagram |
| 15:48.18 | norias | some of these "leaks" aren't much of anything |
| 15:48.25 | starseeker | no joke, that'd be a trivial model |
| 15:48.30 | norias | army "Lessons Learned" are pretty wide distribution |
| 15:52.30 | starseeker | would worry more about some terrorist nuts buying surplus Soviet nuclear weapons on the black market, disassembling them, and making the plans for THOSE public |
| 15:53.24 | starseeker | brlcad: I don't suppose you could use VMware to install Fedora? |
| 15:58.18 | brlcad | I can |
| 15:58.21 | brlcad | but that's still ugh |
| 15:58.24 | starseeker | True |
| 15:59.06 | norias | do i need to raytrace an object before i export it to dxf? |
| 15:59.14 | starseeker | shouldn't |
| 15:59.26 | starseeker | unless you want to take a look at it |
| 15:59.31 | norias | i just tried to export the sphere example |
| 15:59.39 | norias | to see what it'd look like in my 2d cad program |
| 15:59.43 | norias | and i'm having no luck |
| 15:59.50 | starseeker | what's the error? |
| 16:00.23 | norias | do_walk_subtree() FAIL on '/sph1.s' |
| 16:00.27 | norias | 288 triangle written |
| 16:00.37 | norias | i get a file, that has a sph1.s layer on it |
| 16:00.46 | norias | but i can't seem to see any information on it... |
| 16:01.11 | starseeker | Hmm - you just added a sphere to an empty database and tried exporting it, or are you using a pre-existing example file? |
| 16:01.42 | norias | i followed the tutorial |
| 16:01.47 | norias | and just made the initial sphere |
| 16:01.57 | norias | then, |
| 16:02.06 | brlcad | the failure is because it's looking for a region |
| 16:02.19 | norias | oh, ok |
| 16:02.26 | brlcad | it still wrote the sphere though |
| 16:02.33 | norias | so, i have to have a region to get anything exported, really? |
| 16:02.48 | brlcad | no |
| 16:02.51 | brlcad | it should be fine |
| 16:02.56 | brlcad | that's just what that FAIL means |
| 16:03.49 | norias | oh, ok |
| 16:03.52 | norias | hm |
| 16:05.19 | starseeker | I'm not getting anything visible when I load the dxf into Qcad |
| 16:05.31 | norias | yeah, i'm using qcad |
| 16:06.03 | norias | i get list of weird errors if i use -v |
| 16:07.04 | brlcad | not saying it's the problem here, but qcad's dxf importer has *many* bugs |
| 16:08.27 | brlcad | the dxf loads fine in blender |
| 16:09.10 | starseeker | qcad can't see the cassini dxf either |
| 16:09.17 | norias | hmm. bummer |
| 16:09.27 | norias | so it's qcad |
| 16:09.49 | norias | that puts some stones in my shoes as far as what i wanted to do |
| 16:11.09 | brlcad | there are a few things you can try |
| 16:11.40 | brlcad | edit the dxf and remove all of the slashes in the entity names |
| 16:12.16 | brlcad | sed 's/\/sph1.s/sph1.s/g' < yourfile.dxf > newfile.dxf |
| 16:12.24 | norias | hmmm |
| 16:12.26 | norias | good idea |
| 16:12.56 | brlcad | dxf spec allows for a wide range of characters in the names, qcad might not |
| 16:14.35 | norias | hm. basically, figure out what sort of massaging of the data qcad needs |
| 16:14.45 | norias | and maybe write myself a little script for that |
| 16:20.15 | brlcad | if it's something simple |
| 16:20.17 | brlcad | should be |
| 16:20.31 | brlcad | can you make a 3D sphere in qcad? |
| 16:20.51 | brlcad | (not via a revolve) |
| 16:22.35 | norias | can I? no |
| 16:22.38 | norias | can the software? |
| 16:22.41 | norias | i have no idea |
| 16:22.49 | brlcad | heh |
| 16:22.57 | norias | i use it to make 2D mechanical drawins of parts |
| 16:23.07 | norias | blueprinrts |
| 16:23.15 | norias | (wow, my typing is going to hell) |
| 16:23.18 | brlcad | you using qcad on windows? |
| 16:23.40 | brlcad | and did that sed make any difference? |
| 16:23.55 | norias | sed didn't help |
| 16:24.01 | norias | qcad on OS X |
| 16:25.09 | norias | maybe that's the root of the problem |
| 16:25.21 | norias | is that... the exported object is 3d |
| 16:25.28 | norias | and i think qcad only handles 2d |
| 16:26.21 | brlcad | could be |
| 16:26.36 | norias | i was kinda curious how that would play out |
| 16:26.39 | CIA-33 | BRL-CAD: 03brlcad * r30533 10/brlcad/trunk/src/other/openNURBS/opennurbs_system.h: try to fix the fedora linkage error (blindly). these are C headers, so protect them with an extern C declaration if we're compiling in C++ mode. |
| 16:26.39 | norias | guess i know now |
| 16:26.41 | norias | it won't |
| 16:27.12 | brlcad | submit a bug report ;) |
| 16:27.33 | norias | doesn't sound like a bug to me |
| 16:27.38 | norias | well... not for brl |
| 16:27.49 | norias | and, i'm thinking not really a bug for qcad |
| 16:27.52 | brlcad | i meant a qcad bug report |
| 16:27.54 | brlcad | and in jest :) |
| 16:27.57 | norias | because i don't think it's supposed to do 3d |
| 16:28.00 | norias | oh, right on |
| 16:31.55 | norias | hmmm, solidworks has a free viewer |
| 16:32.13 | norias | kinda helps... a little... |
| 16:33.09 | brlcad | what're you trying to do? |
| 16:33.22 | brlcad | if you're trying to better visualize, you can use the "rt" command |
| 16:33.31 | norias | hmm, basically... i'd like to lay things out with brl-cad in 3d |
| 16:33.40 | norias | then turn it out into 2d images |
| 16:34.00 | norias | that i can add dimensions etc, for working drawings |
| 16:34.06 | brlcad | ah, k |
| 16:34.21 | brlcad | run "rtedge" |
| 16:34.26 | norias | oh? |
| 16:34.48 | brlcad | that'll generate hidden line drawings |
| 16:34.52 | brlcad | e.g. http://brlcad.org/OLD/images/havoc_rtedge.png |
| 16:35.14 | brlcad | just without dimensions |
| 16:35.24 | norias | that's kinda close to what i'm after |
| 16:35.36 | brlcad | but they can of course be added to the image afterwards with fav image editor |
| 16:35.51 | brlcad | yeah, you probably want the orthogonal views |
| 16:36.03 | norias | right |
| 16:36.04 | brlcad | maybe something not quite so complex |
| 16:36.18 | norias | orthogonal views is exactly the idea |
| 16:36.38 | norias | i'm not even 100% sure, because i'm not any sort of engineer |
| 16:36.47 | brlcad | yeah, i've been meaning to write a little wrapper that generates a standard multi-view hidden-line rendering all at once |
| 16:36.51 | norias | i make the stuff, and i know what it needs to look like fore me to make it |
| 16:37.34 | norias | and, i can make those drawings with qcad or whatever |
| 16:37.51 | norias | and i can make 3d models to look at by importing them into sketchup |
| 16:38.02 | norias | (even though the dimensional accuracy is then... terrible) |
| 16:38.13 | norias | i'd like be able to go the other way |
| 16:38.49 | brlcad | something like http://c900se.files.wordpress.com/2007/12/diagram-1992_saab-900-cabriolet.gif |
| 16:39.10 | norias | yeah, vaguely |
| 16:39.24 | norias | i could toss an example of a single piece |
| 16:39.29 | norias | that i did with qcad |
| 16:39.44 | norias | (even though it's technically wrong) |
| 16:40.29 | brlcad | yeah, be useful to see |
| 16:40.56 | norias | there's too many views on mine |
| 16:41.05 | norias | i was told by a friend who's a professional drafter |
| 16:41.10 | norias | but i guess it gives the idea |
| 16:41.24 | brlcad | better to have too much than too little |
| 16:41.36 | norias | that's my thought |
| 16:41.46 | norias | but the drafting... they have their own standards, too |
| 16:41.52 | norias | so, it doesn't fit the standard |
| 16:42.31 | norias | but then, it's alot closer than i was before :) |
| 16:42.41 | norias | http://base.google.com/base/a/2422661/D6214409695575134655 |
| 16:42.53 | norias | the pdf file on that page is the actual document |
| 16:43.44 | brlcad | yeah, something like http://www.draftingzone.com/standards/standard1/ |
| 16:44.25 | norias | yeah |
| 16:44.41 | norias | not that people actually follow it... |
| 16:44.46 | brlcad | :) |
| 16:44.51 | norias | i was just making a drawing |
| 16:45.00 | norias | based on what i knew from having seen 1000's of them |
| 16:45.06 | norias | to describe an object i was making at home |
| 16:45.20 | norias | apparently i have two too many views |
| 16:47.13 | norias | i'm thinking... basically the multipane mged view |
| 16:47.49 | norias | shoved into a file |
| 16:51.14 | starseeker | Hmm - this is pretty darn cool looking: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300206000053 |
| 16:52.06 | norias | those are pretty cool |
| 16:52.23 | norias | i found some blueprints for the m1911 45 caliber pistol |
| 16:52.33 | norias | those are neat, imho |
| 16:52.42 | starseeker | I guess that price isn't too bad considering how many blueprints there are, but still... urk |
| 16:52.46 | starseeker | neat |
| 16:52.50 | starseeker | originals? |
| 16:53.05 | norias | yeah |
| 16:53.14 | norias | well, scanned pdf of the originals |
| 16:53.18 | starseeker | neat |
| 16:53.24 | starseeker | link? ;-) |
| 16:53.32 | norias | that might be one of my "learning cad" projects |
| 16:53.38 | norias | to turn them into a .dxf |
| 16:53.43 | norias | hmm, link... i dunno |
| 16:53.54 | norias | i downloaded 'em from somewhere... |
| 16:54.11 | norias | i can put them on my google base account if you want |
| 16:54.23 | starseeker | are they copyrighted? |
| 16:54.30 | norias | no idea |
| 16:54.37 | norias | good question, actually |
| 16:54.44 | norias | can't image at this point it'd be a big deal |
| 16:54.52 | starseeker | heh |
| 16:54.54 | norias | 20 thousand companies make 1911's |
| 16:55.15 | norias | it's not like the dimensions of the things are some huge secret |
| 16:55.43 | starseeker | true |
| 16:56.01 | starseeker | sees a fair number of 1911 blueprints on ebay |
| 16:56.08 | starseeker | not originals, but copies |
| 16:56.12 | norias | yeah |
| 16:56.33 | norias | i think it'd be fun to make one someday |
| 16:56.39 | starseeker | :-) |
| 16:56.41 | norias | when i get hold of a milling machine |
| 16:57.00 | norias | (or an employer that let's me use the machines on off time) |
| 16:57.15 | starseeker | That'd be interesting if you tried to register it with police - "Manufacturer? Me in my garage officer, honest!" ;-) |
| 16:57.19 | norias | i had an interview with a company that makes components for machine guns |
| 16:57.25 | starseeker | cool |
| 16:57.32 | norias | actually, in the US, it's totally legal to make your own firearms |
| 16:57.41 | norias | and in my state, there are no firearms registrations |
| 16:58.10 | starseeker | that works |
| 16:58.10 | norias | you can legally make any firearm that you could legally purchase |
| 16:58.17 | norias | so long as you do all the work yourself |
| 16:58.20 | norias | and never sell it |
| 17:00.14 | norias | nice... |
| 17:00.41 | norias | this CAD viewer opens the dxf that brl made |
| 17:01.02 | norias | now i see why it's called a bag of triangles |
| 17:01.06 | starseeker | hehe |
| 17:16.05 | norias | so, brl-cad can do ballistics simulations? or no? |
| 17:21.20 | brlcad | ballistic simulation codes use brl-cad (directly) |
| 17:21.43 | brlcad | but we don't include the code in brl-cad that does the actual penetration simulation |
| 17:22.08 | brlcad | that's a separate analysis code, one of many that use brl-cad for high-performance geometry interrogation |
| 17:22.59 | norias | so, basically... it does external ballistics.. |
| 17:23.11 | yukonbob | waves in |
| 17:23.16 | norias | i.e. if i modelled a projectile for a rifle... |
| 17:23.18 | brlcad | the closest brl-cad lets you get to that are the tools for computing weights/moments and projected areas |
| 17:23.36 | brlcad | howdy yukonbob |
| 17:23.41 | norias | i could model it's external ballistics? |
| 17:23.45 | norias | (i.e. flight path) |
| 17:23.51 | norias | or no? |
| 17:24.26 | brlcad | with what? |
| 17:24.55 | brlcad | with brl-cad, no -- it provides the fundamental geometric representation and API facilities for querying that representation |
| 17:25.01 | norias | ok |
| 17:25.18 | brlcad | there are various (other) analysis codes that hook into that API for doing the simulations |
| 17:26.12 | brlcad | those include things like simulating material interactions, energy transmission, flight-path simulations, etc |
| 17:27.26 | brlcad | so you could model the projectile for a rifle and there are codes that will simulate its behavior in a given encounter scenario |
| 17:29.52 | norias | hmmm |
| 17:29.54 | norias | interesting |

| 18:00.09 | brlcad | norias: curious, in your example, the dimensions on the center for .492 and .244 don't seem right |
| 18:01.10 | brlcad | if the base is .170 up and top of that cylinder is .260 up (right diagram), then .244 for the center of that .250R seems wrong |
| 18:04.41 | norias | it's possible |
| 18:04.45 | norias | i'm still learning |
| 18:04.53 | norias | and some of the numbers are a little fudged |
| 18:05.06 | norias | mostly because not all of the dimensionals are functional |
| 18:05.25 | norias | they are just.... to make the piece more attractive |
| 18:06.08 | norias | lemme look, though... |
| 18:07.51 | norias | i see your point... |
| 18:07.57 | norias | that doesn't seem to make sense |
| 18:08.46 | norias | at all |
| 18:09.04 | norias | also interesting that you caught that |
| 18:09.13 | norias | and the professional drafter i showed it to didn't |
| 18:10.31 | norias | yeah, the .492 should be .170 - .040 (for the radius) |
| 18:10.36 | norias | hence, .130 |
| 18:11.09 | norias | i'm set to do another version |
| 18:11.36 | norias | off some models i did of this piece in relation to the other parts in the assembly |
| 18:11.55 | norias | which gave me some different theoretical values |
| 18:12.01 | norias | close, but it makes a difference |
| 18:12.02 | norias | so, yeah |
| 18:12.04 | norias | good catch |
| 18:12.35 | norias | i think both the .492 and .244 are wrong |
| 18:16.34 | brlcad | k :) |
| 18:17.58 | norias | btw, is there a repository somewhere for free brl-cad models? |
| 18:35.57 | brlcad | norias: there are a variety included in your install |
| 18:36.18 | brlcad | look in /usr/brlcad/share/brlcad/7.XX.X/db |
| 18:39.36 | brlcad | norias: also curious, noted in your diagram that you have the top at a 5 deg incline, yet the google picture seems pretty horizontal |
| 18:42.38 | norias | i think that's just a perspective issue |
| 18:43.16 | brlcad | hm, k |
| 18:43.38 | norias | lemme look, though |
| 18:43.42 | brlcad | plays with the model |
| 18:43.54 | norias | because the picture is a just a picture of the 3d model |
| 18:44.10 | norias | so i should be able to tell pretty quick |
| 18:44.20 | norias | (the 3d model comes directly from the diagram) |
| 18:45.03 | norias | definitely a perspective issue |
| 18:47.40 | norias | just added another picture |
| 18:47.42 | norias | that shows |
| 19:08.50 | brlcad | woot, http://brlcad.org/tmp/extractor.png |
| 19:09.07 | brlcad | thats a fun lil shape |
| 19:10.00 | brlcad | created exactly per your dimensions |
| 19:18.07 | brlcad | http://brlcad.org/tmp/extractor2.png |
| 19:19.42 | norias | wow |
| 19:19.46 | norias | that's really neat |
| 19:20.34 | norias | so the dimensions were good, then? |
| 19:21.00 | brlcad | i'm not an expert modeler, there's probably some optimizations that I could have used, but it was easy enough to reconstruct |
| 19:21.33 | brlcad | yeah, the dimensions seemed alright except for those two mentioned |
| 19:21.38 | norias | oh, ok |
| 19:21.59 | norias | how'd you get a center point for that radius, then? |
| 19:22.10 | brlcad | and given they were wrong, it made positioning the main arc interesting :) |
| 19:22.32 | norias | just eyeballed it? |
| 19:24.42 | brlcad | well, the overall width is known and it's nearly tangent to the outer edge |
| 19:25.17 | brlcad | that gives a horizontal -- i did just eyeball the vertical at .180 |
| 19:25.55 | norias | yeah, well, the numbers for that center point... and the size of that radius are just a "guess" anyway |
| 19:26.10 | norias | it's not at all functional, just to make it look nice installed |
| 19:26.24 | brlcad | ah |
| 19:26.27 | norias | so, .250 for the radius just because it's easy to make, and a standard size |
| 19:26.37 | brlcad | i thought you had measured one :) |
| 19:26.57 | norias | then the centerpoint found just by lining that up with the straight line for the angle, and the extractor lip |
| 19:27.06 | norias | yeah, i actually made one by hand |
| 19:27.21 | norias | by measuring where it needed to fit, and what it needed to do |
| 19:27.28 | brlcad | is that r250 angle also 5 degrees? |
| 19:27.34 | norias | and the blueprint is based off those measuremeants |
| 19:27.54 | norias | R.250 is the size of the radius on the "front" |
| 19:28.08 | norias | and the 5 degrees is also a "look" nice thing |
| 19:29.38 | norias | i have a "third edition" soon... |
| 19:29.42 | norias | based on notes, etc |
| 19:29.48 | norias | because i might make a few more of these |
| 19:30.05 | norias | considering starting the process in BRl-cad |
| 19:30.19 | norias | then moving it to my regular cad environment for the working prints |
| 19:30.37 | norias | not sure if i'll make them soon, because doing it by hand is a PITA |
| 19:30.56 | norias | or, maybe even take a good print to a local shop and get it priced for a small run |
| 19:31.19 | norias | probably not, though |
| 19:31.31 | norias | when i started this, the part was unavailable |
| 19:31.36 | norias | so, i was forced to make one |
| 19:31.41 | norias | they are available now |
| 19:31.52 | brlcad | oh yeah |
| 19:31.54 | norias | i didn't even know what it needed to look like |
| 19:32.00 | norias | just where it went, and what it did |
| 19:32.02 | brlcad | noticed another minor discrepancy |
| 19:32.05 | norias | ? |
| 19:32.27 | brlcad | on the left side, where the R.250 arrow meets up |
| 19:32.45 | norias | yes? |
| 19:32.58 | brlcad | if that's the radius, then the 119+131 below are slightly off :) |
| 19:33.00 | norias | oh, i think i see... |
| 19:33.06 | brlcad | as they are inside |
| 19:33.07 | norias | yeah, i know those are off |
| 19:33.16 | norias | i noticed that after i called it "quits" |
| 19:33.19 | brlcad | would be saying tan(5) == 0 :) |
| 19:33.35 | norias | (actually when i was trying to make one) |
| 19:34.03 | norias | it's been a learning experience |
| 19:34.12 | norias | before this i never touched CAD software, at all |
| 19:34.24 | norias | i just make things in a shop |
| 19:34.28 | brlcad | cool |
| 19:34.34 | norias | and know kinda what the prints need to look like |
| 19:34.57 | brlcad | I mostly only touch CAD software and rarely make things in a shop ;) |
| 19:35.13 | norias | yeah, eventually... |
| 19:35.25 | norias | i'm going to school to be a mech engineer |
| 19:35.43 | brlcad | if you would like to play with that .g, its also up there in the tmp dir |
| 19:35.54 | norias | i'm trying to learn/teach myself all this stuff from the ground up |
| 19:35.58 | norias | instead of the other way around |
| 19:36.25 | brlcad | http://brlcad.org/tmp/extractor.g |
| 19:36.31 | norias | tempting... |
| 19:37.08 | brlcad | fixes apache's mime type |
| 19:38.47 | norias | is archer a big advance over mged? |
| 19:40.06 | yukonbob | brlcad: what's the ETA for tagging latest 7.10.x |
| 19:40.44 | brlcad | norias: usability wise, yes -- but it's lacking tons of functionality |
| 19:41.03 | brlcad | it's the start of a new user interface, a redesign, a prototype |
| 19:41.09 | brlcad | yukonbob: later today |
| 19:41.37 | yukonbob | !! woohoo |
| 19:41.39 | yukonbob | :) |
| 19:42.01 | yukonbob | prepares |
| 19:42.11 | yukonbob | is .6? |
| 19:42.16 | brlcad | 7.12.0 |
| 19:42.19 | yukonbob | ha |
| 19:42.20 | yukonbob | *ah |
| 19:42.50 | brlcad | this will actually be one of our biggest feature-wise in a long time |
| 19:42.59 | brlcad | more than 75 items |
| 19:43.00 | yukonbob | is looking forward to it... |
| 19:43.18 | norias | of course... i download the old one the day before... |
| 19:43.23 | brlcad | :) |
| 19:43.32 | brlcad | it's alright, we might not make full binaries for this release |
| 19:43.34 | yukonbob | heh -- isn't that how new releases are made? |
| 19:43.42 | brlcad | maybe just mac, linux, windows or someset thereof |
