| 18:43.54 | v4 | hallo i have a very simple question. |
| 18:43.57 | v4 | may i? |
| 18:44.37 | v4 | i just downloaded the bel-cad package for mac. |
| 18:44.58 | v4 | when I double click on the app icon |
| 18:45.17 | v4 | it start the mged |
| 18:45.56 | v4 | but i wanted to import a .stl file … and looks like it's not possible from here ... |
| 18:46.13 | v4 | it's like i should start another application (the proper BRL-CAD) |
| 18:46.28 | v4 | but i just don't know how to do that ... |
| 18:46.52 | v4 | can anybody, maybe help me somehow? |
| 18:46.55 | v4 | thank in advance |
| 19:13.08 | n_reed | v4: MGED is the main app, but it only edits .g files |
| 19:13.20 | n_reed | open a terminal and run stl-g on your .stl first |
| 19:14.05 | v4 | yeah, i was just arrived at his point … searching on the net … should i execute the command as root? |
| 19:14.18 | v4 | (by the way thank you) |

| 19:17.32 | v4 | yes |
| 19:18.55 | starseeker | I'm not sure why it's looking for the library there when we've got an app bundle... |
| 19:19.18 | starseeker | you can probably make it work if you install BRL-CAD in the /usr/brlcad/ directory |
| 19:20.23 | v4 | ok thanks, i'll try this then |
| 19:22.35 | v4 | shall I have to install the content of the package in the /usr/brlcad ? Or just drag the icon, as usual? |
| 19:23.31 | starseeker | I'm not sure - however you do it, try to get the contents of Contents/Resources/rel-7.22.0 into /usr/brlcad/rel-7.22.0 |
| 19:25.53 | v4 | ok, but same error |

| 19:26.30 | starseeker | is the file /usr/brlcad/rel-7.22.0/lib/libwdb.20.dylib present? |
| 19:28.38 | v4 | yeah, good question … and nope. |
| 19:29.00 | v4 | i only have these: |
| 19:29.01 | v4 | libwdb.20.0.1.dylib |
| 19:29.15 | v4 | libwdb.a |
| 19:29.30 | starseeker | hmm... |
| 19:29.52 | starseeker | well, you can try symlinking libwdb.20.0.1.dylib to libwdb.20.dylib |
| 19:30.18 | v4 | seems reasonable ... |
| 19:30.41 | starseeker | if libwdm's link is messed up, there may be more that are messed up... |
| 19:30.54 | v4 | how is that possible? |
| 19:31.02 | v4 | I just downloaded the whole package |
| 19:31.05 | starseeker | ln -s libwdb.20.0.1.dylib libwdb.20.dylib |
| 19:31.13 | starseeker | v4: it would be a problem with our package |
| 19:31.22 | starseeker | brlcad is our expert on that |
| 19:31.23 | v4 | ah, ok … |
| 19:31.53 | starseeker | this would be a temporary manual fix, but it would get you running |
| 19:32.06 | v4 | i'll try in a few sec |
| 19:32.53 | v4 | similar problems with another library |
| 19:32.54 | v4 | dyld: Library not loaded: /usr/brlcad/rel-7.22.0/lib/librt.20.dylib |
| 19:33.16 | v4 | you got it right … maybe more is messed up ... |
| 19:33.40 | starseeker | ok, same solution - ln -s librt.20.0.1.dylib librt.20.dylib |
| 19:34.11 | v4 | yeah, there's more |
| 19:34.16 | v4 | i try to correct 'em all |
| 19:34.29 | starseeker | v4: that ought to work, once you've got 'em all |
| 19:35.36 | v4 | ok! |
| 19:35.43 | v4 | (hope so) |
| 19:41.57 | v4 | ok the command stl-g now works |
| 19:42.13 | v4 | but my .stl file must have some errors |
| 19:42.52 | v4 | … but this is definitely not a software problem (at least i guess so) |
| 19:43.06 | starseeker | what type of stl file is it? (ascii text or binary?) |
| 19:43.47 | v4 | i'm sorry: today was the first time i use this kind of files and software … i do not have any idea of that … |
| 19:44.33 | v4 | tomorrow i will work at the same 3d scan workstation, i'll be more prepared ... |
| 19:44.34 | starseeker | if you open your .stl file in a text editor, what do you see? (i.e. does it just look like garbage, or is there content you can recognize) |
| 19:44.44 | v4 | i'll try this |
| 19:44.50 | starseeker | alternately, what was the error you saw? |
| 19:46.30 | v4 | the terminal just got crazy when i prompted the stl-g input.stl output.g |
| 19:46.36 | starseeker | oh |
| 19:46.41 | starseeker | did you specify an output file? |
| 19:47.07 | v4 | yes … shouldn't i do that? |
| 19:47.11 | starseeker | yeah |
| 19:47.20 | starseeker | oh - that was your literal command? |
| 19:47.22 | v4 | anyway the text editor is garbage … as you said |
| 19:47.29 | starseeker | try adding the -b flag |
| 19:47.34 | v4 | ok |
| 19:47.38 | starseeker | stl-g -b input.stl output.g |
| 19:48.10 | v4 | way better :) |
| 19:48.23 | v4 | Using solid name: s.stl |
| 19:48.24 | v4 | 2067731 facets |
| 19:48.24 | v4 | Making region (r.stl) |
| 19:50.30 | v4 | the .g file is now openable |
| 19:50.46 | v4 | but i don't see anything when i try to open it in mged |
| 19:50.58 | starseeker | you won't by default. |
| 19:51.04 | v4 | ah, ok |
| 19:51.08 | v4 | … so it's ok! |
| 19:51.18 | starseeker | try the command "tops" |
| 19:51.24 | starseeker | what is listed in the terminal? |
| 19:51.39 | v4 | answered all/ |
| 19:51.52 | starseeker | OK - to see a wireframe, do "draw all" |
| 19:52.06 | v4 | wow!!!! |
| 19:52.09 | v4 | yep! |
| 19:52.11 | v4 | :) |
| 19:52.19 | v4 | i got to thank you, man ... |
| 19:52.27 | starseeker | if you want the shaded version, I think it's "draw -m1 all" |
| 19:52.41 | starseeker | (you will also want to turn on lighting if you do that...) |
| 19:53.14 | v4 | may i ask you one last thin, seeing you were so kind? |
| 19:53.34 | starseeker | lighting is under the Misc menu in MGED, at the bottom of the menu |
| 19:54.19 | v4 | yeah … now i see it even better! |
| 19:54.24 | starseeker | sure - what's the question? |
| 19:54.47 | v4 | what i really have to do, is to try to draw some lines directly on the 3D scan … i mean not converting the file I got from the scan into a 2D ... |
| 19:55.01 | v4 | do you think is possible? with this or other software? |
| 19:55.37 | ``Erik | sunny beaches, mail parsing makes xml ... attractive. :( |
| 19:55.52 | starseeker | Um... we shouldn't be converting to 2D now... |
| 19:56.01 | starseeker | do you you want a 2D line drawing output? |
| 19:56.27 | v4 | i mean … i have this lines on the scan (it's a wall!) i have to draw them on the 3d |
| 19:56.36 | v4 | and then maybe have a 2d output |
| 19:56.49 | v4 | (this last part is still not completely clear() |
| 19:57.04 | v4 | but the most important is to draw the lines directl |
| 19:57.07 | v4 | on the 3d |
| 19:57.10 | v4 | file |
| 19:57.28 | starseeker | we don't have a way to just straigt-up draw 3D lines in MGED... you can "fake it" by doing thin cylindars |
| 19:57.36 | v4 | ok ... |
| 19:58.09 | v4 | now i will tell a stupidity … there is not a tool such a brush |
| 19:58.16 | v4 | (i mean like photoshop …) |
| 19:58.48 | starseeker | ok, brace yourself... |
| 19:59.06 | starseeker | MGED's primary mode of geometry creation is command line input |
| 19:59.28 | ``Erik | "mged -c" for the pure experience O:-) |
| 19:59.28 | v4 | yes |
| 19:59.35 | v4 | ok! |
| 20:00.10 | starseeker | If you haven't seen it yet, you want to read http://brlcad.org/w/images/c/cf/Introduction_to_MGED.pdf |
| 20:00.32 | v4 | i think i have to study it, pretty hard ... |
| 20:00.44 | v4 | you mean .. i have to "create" such a tool? |
| 20:01.15 | ``Erik | BRL-CAD's legacy is in CAE/CAA, not CAD... if it's not a physical 3d bit of geometry, it doesn't fit in very well, so we don't have good support for things like lines |
| 20:01.18 | starseeker | I'm afraid so. The quickest way I can think of to get a "3d line" would be to make a tgc, and then edit its shape to be long and have a small radius |
| 20:01.43 | v4 | ok, got it. |
| 20:01.55 | ``Erik | meh, just call it an rcc, less knobs to twiddle |
| 20:02.01 | v4 | @erik … you should change its name then ;) |
| 20:03.13 | v4 | just kidding of course ... |
| 20:03.22 | v4 | thank you alls for your patience with a super newbie |
| 20:03.33 | v4 | all* |
| 20:03.38 | starseeker | we're getting there, little by little - the problem with most of the features associated with "modern" CAD is it requires a lot of behind the scenes work |
| 20:03.49 | starseeker | v4: not at all - thank you for trying it out! |
| 20:04.09 | v4 | :) |
| 20:05.06 | starseeker | v4: the introduction to MGED book should get you going with the basics, and once you're familiar with them you should be able to produce some decent images |
| 20:05.37 | v4 | ok, i'll read it with big attention |
| 20:24.09 | v4 | by guys … i think i will pass from here in the future, if i go on with this software … |
