| 04:23.11 | leed | Hello everyone. I want to use brlcad build a 3d model and convert it to ACIS format. |
| 04:23.40 | brlcad | leed: hello leed |
| 04:24.13 | brlcad | you'll have to use an intermediary format at the moment as there's no direct path |
| 04:24.35 | brlcad | there is an experimental SAT exporter under development, but it's not ready for even testing use |
| 04:25.21 | brlcad | so you'd have to use one of the export formats: http://ftp.brlcad.org/tmp/converters_page23.jpg |
| 04:26.52 | leed | brlcad: I have never used brlcad before. I want to whether brlcad can deal with my problem. If the answer is yes, I will learn how to use brlcad. |
| 04:28.14 | brlcad | leed: fair enough |
| 04:28.38 | brlcad | it's a common misperception (that I'm working on addressing with the new website) as to what brl-cad actually is and does |
| 04:28.50 | brlcad | where it's strengths and weaknesses and capabilities are at |
| 04:29.22 | brlcad | we're not autocad in the least for example, nor do we really cater to drafting or other 2D modeling features very well (or at all in some cases) |
| 04:29.43 | brlcad | so, what's your problem? |
| 04:32.52 | leed | I want to build a 3d model and convert to ACIS format. Then I can import it to Gambit. |
| 04:34.05 | leed | I have only use ACIS format so far. |
| 04:36.41 | leed | If there are some more effective means, please let me know. |
| 04:42.09 | brlcad | well, that's pretty general requirements actually :) |
| 04:42.21 | brlcad | you can certainly build 3d models and export to formats that acis will read |
| 04:42.45 | brlcad | though they will be polygonalized, and you'll have to learn a fair bit of how to model using mged beforehand |
| 04:42.55 | brlcad | they will, however, be solid models |
| 04:43.40 | brlcad | shame our SAT exporter isn't complete -- that actually integrates well with Cubit |
| 04:44.58 | brlcad | could possibly get you to be a beta tester for it, though you'd need to acquire a Cubit license to use the binary iirc |
| 04:51.19 | leed | Thank you for your suggestion. |
| 04:52.09 | leed | I think I need some time to learn how to use brlcad at first. |
| 04:55.35 | brlcad | have you downloaded the tutorial series? |
| 04:56.01 | brlcad | that will take you through some of the basics (and are pretty much required reading to have any proficiency) |
| 04:56.15 | brlcad | and give you an idea of whether the interface can work for you |
| 04:57.04 | leed | I am downloading brlcad-7.8.0_linux_ia32.tgz right now. |
| 05:00.04 | leed | Thanks for your help. I get go now. |

| 21:27.41 | dli | can I import a part from another database file? |
| 21:36.33 | brlcad | yep |
| 21:37.52 | brlcad | the 'proper' way is to run the "dbconcat" command or similarly File -> Import .. those will check for name collisions and rename for you |
| 21:38.20 | brlcad | or you can simply "cat" the files together on the command line, the result .g will warn about multiple _GLOBAL entries, but it will be valid |
| 21:42.16 | brlcad | of, if you just want a portion of another database file, do a "keep" operation (or File -> Export) on the objects you want, and then import those |
| 21:57.01 | dli | brlcad, thanks. |

| 22:41.09 | dli | louipc, my picture? it's a Ultra-High-Vacuum chamber |
| 22:41.34 | louipc | fancy |
| 22:42.01 | louipc | I need to start modeling some things |
| 22:42.12 | louipc | I don't know what though hahh |
| 22:42.57 | dli | louipc, follow the tutorial (as I did) is a must |
| 22:43.03 | louipc | yeah |
| 22:43.21 | louipc | I'll probably have to do the tutorial again. It's been a long time |
| 22:43.36 | louipc | but I don't know what I want to model |
| 22:43.40 | dli | louipc, it's much more complex then I imagined. since I haven't finished the tutorial yet |
| 22:43.48 | louipc | maybe I'll design a guitar yeah! |
| 22:45.05 | dli | louipc, what about 2D cad, like qcad |
| 22:45.30 | louipc | dli: what about it? |
| 22:45.30 | dli | louipc, I need blueprints for the machine shop, still rely on qcad |
| 22:46.00 | dli | louipc, a very simple blueprint from qcad: http://saras-bhat.uchicago.edu/si0.png |
| 22:46.05 | louipc | I use solidworks dwg editor at work |
| 22:47.29 | louipc | hehe qcad might be better, I never considered that |

| 22:48.38 | louipc | dli: yeah. I know. |
| 22:48.48 | dli | louipc, a little bit more complex from qcad: http://saras-bhat.uchicago.edu/cell9a.pdf |
| 22:49.27 | dli | louipc, you draw basically the old way |
| 22:49.56 | louipc | hey.. that's 3d :P |
| 22:50.42 | louipc | but you had to draw that manually? |
| 22:50.44 | dli | louipc, yes, the way I learnt during my college course: engineering drawing |
| 22:51.12 | louipc | how do you do the radius' properly? |
| 22:51.18 | louipc | interesting |
| 22:51.35 | dli | louipc, projection of circles :) |
| 22:52.10 | louipc | hmm I've never done projection of circles. that's neat though |
| 22:52.30 | dli | louipc, if you know how to project x- y- z-, then, you can work out the equation for circle |
| 22:54.14 | louipc | is that 35 degree tilt? |
| 22:55.23 | dli | louipc, yes, http://en.wikipedia.org/wiki/Isometric_projection |
| 22:55.45 | louipc | yeah, so with that math you can draw at any other angle eh? |
| 22:55.57 | louipc | hah I never learned that |
| 22:56.08 | louipc | well I know what isometric is |
| 22:56.26 | dli | louipc, hehe, I got A in my drawing course, only found it's so much easier with qcad |
| 22:56.54 | louipc | I've never touched a drafting table :/ |
| 22:57.43 | dli | louipc, better, most valuable part is the design, you can always hire someone to make the drawings |
| 22:57.59 | louipc | I've only used computers I mean |
| 22:59.02 | dli | louipc, we had to start we pencil and rubber, good education still |
| 22:59.10 | louipc | yeah definitely |
| 22:59.31 | louipc | + protractor, straightedge, compass, square hah |
| 23:01.23 | dli | louipc, I wonder whether it's possible for brl-cad to merge some codes from qcad, and support drafting |
| 23:03.11 | louipc | yeah that would be handy |
| 23:04.47 | louipc | dli: do you know how to draw perspective view? |
| 23:05.49 | dli | louipc, no, I think it's something like the last chapter in my course, but I have forgotten all :( |
| 23:05.59 | louipc | aw |
| 23:07.46 | deltazap | dli: what OS do you use qcad with? |
| 23:08.05 | dli | deltazap, linux |
| 23:08.31 | deltazap | ok, i'm wondering if it's just me that has a problem with it on the mac |
| 23:08.34 | deltazap | it just doesn't feel right |
| 23:08.43 | dli | deltazap, for example? |
| 23:08.57 | louipc | deltazap: I used qcad before on linux, and it felt a bit strange |
| 23:09.08 | deltazap | just as an app on mac, it just doesn't fit well |
| 23:09.19 | deltazap | i'm way to use to the 'way things work' |
| 23:09.55 | deltazap | but, that won't matter much as i'm about to get a student copy of autocad or pro/e at the lab |
| 23:18.09 | deltazap | yet i'll probably end up using brlcad |
| 23:18.58 | louipc | not for 2d eh? |
| 23:19.14 | deltazap | probably not |
| 23:19.37 | deltazap | more for 3d models so i can show people what i plan to build |
| 23:19.57 | deltazap | but we'll see how it goes and how good i can get |
| 23:23.01 | deltazap | is there a way to have placeholder objects and then easily replace them in the model? |
