| 00:26.30 | bjrohan | hi |
| 00:35.24 | starseeker | howdy |
| 00:48.30 | bjrohan | I had been a machinist for 12 years, ending about 5 years ago. I was asked today to help an old co-worker. His shop is new, and he has no CAD program (goes completely off of prints). I am looking for a FOSS Cad to verify dimensions on 2d dxf / dwg files on a Linux machine, will BRLCAD be able to do this fairly easily? |
| 00:48.42 | bjrohan | intuitively I should say |
| 00:49.04 | starseeker | intuitively, probably not |
| 00:49.15 | starseeker | for 2D, I'd suggest looking at librecad |
| 00:50.09 | starseeker | dwg files are likely to be a problem for most FOSS software, but dxf should be OK |
| 00:50.48 | bjrohan | ok |
| 00:51.58 | bjrohan | That makes sense. |
| 01:28.00 | Notify | 03BRL-CAD:n_reed * 63194 brlcad/branches/brep-debug/src/libbrep/intersect.cpp: Surface BoundingBox() routine was failing for a planar surface for some unknown reason. Implement a fallback for when the routine fails. |

| 02:16.21 | bjrohan | starseeker: well, I tried LibreCAD and FreeCAD, I had downloaded a random dxf file, and neither of those showed the dxf as I expected. I am trying to import into BRL-CAD, I enter dxf-g /home/bjrohan/Downloads/Mechanical_Sample.dxf Mechanical_Sample.g and I get the error message that dxf-g unknown command |
| 02:16.26 | bjrohan | any suggestions? |
| 03:47.44 | *** join/#brlcad FreezingCold (~FreezingC@135.0.41.14) |
| 04:12.31 | brlcad | bjrohan: you'll need to make sure your path is properly set to run command line applications, or provide a full-path to dxf-g |
| 04:13.04 | brlcad | e.g., if brl-cad is installed in /usr/brlcad/rel-7.22.0, the full path to dxf-g is probably /usr/brlcad/rel-7.22.0/bin/dxf-g |
| 04:14.42 | bjrohan | brlcad: is there a way to specify this in a config file? |
| 04:14.55 | bjrohan | vs entering the entire path to dxf-g |
| 04:16.36 | brlcad | absoultely, that was the first option (make sure your path is properly set to run command line applications) |
| 04:17.06 | brlcad | how to do that depends on your shell (and has nothing to do with brl-cad) ;) |
| 04:19.00 | brlcad | running "export PATH=/path/to/that/bin/dir:$PATH" will do the trick for bash-based shells, you can put that into a ~/.bash_profile if you're using bash ... but really this depends on the shell you're using |
| 04:20.45 | brlcad | make sure it runs full path, to make sure you know which path you need to be adding, then figure out how to update your PATH for your shell (read your shells docs, or ask for help here if someone is around, or search the web .. this is an intro/faq linux topic), then make the change and confirm it works with a new shell |
| 04:31.38 | bjrohan | brlcad: I am using Ubuntu 14.04 with bash |
| 04:36.40 | bjrohan | brlcad: on my system /usr/brlcad contains: bin etc include lib share version, I am searching for dxf-g now |
| 04:44.29 | brlcad | so full path is probably /usr/brlcad/bin/dxf-g |
| 04:45.35 | bjrohan | Yep |
| 04:45.55 | bjrohan | to add this to my path is: |
| 04:45.56 | bjrohan | export PATH=/usr/brlcad/bin/dxf-g:$PATH |
| 04:45.58 | bjrohan | ? |
| 04:54.55 | bjrohan | brlcad: In my /etc/profile.d is a file brlcad.sh which includes the correct path, however, dxf-g isn't recognized |
| 04:56.15 | brlcad | that is not the way to update PATH |
| 04:57.14 | brlcad | bjrohan: suggest reading http://www.linfo.org/path_env_var.html |
| 04:57.17 | brlcad | or http://superuser.com/questions/517894/what-is-the-unix-path-variable-and-how-do-i-add-to-it |
| 04:57.41 | brlcad | you specify directories to PATH |
| 04:58.00 | brlcad | rather, PATH is literally a list of directories |
| 04:58.14 | brlcad | places to look for applications |
| 04:58.34 | brlcad | adding to /etc/profile.d sounds wrong/unnecessary |
| 04:59.19 | brlcad | you can set the path in your own config files that live in your home dir |
| 05:00.21 | brlcad | if you did want to set them for all users, that might be how your system is set up (see 'man bash'), but you shouldn't be doing any editing until you did those other steps I mentioned |
| 05:00.54 | brlcad | i.e., make sure it runs full path, to make sure you know which path you need to be adding, then figure out how to update your PATH for your shell (read your shells docs, or ask for help here if someone is around, or search the web .. this is an intro/faq linux topic), then make the change and confirm it works with a new shell |
| 05:01.00 | brlcad | you jumped to the last step and got it wrong |
| 05:01.27 | brlcad | good luck |
| 05:03.17 | bjrohan | Thank you. Ubuntu I think has unusual settings. my .profile has only a few lines to it, and not a typical PATH variable |

| 05:14.56 | brlcad | bjrohan: it doesn't matter if there are lines already for changing the PATH ... you add your path settings to your config file |
| 05:16.26 | bjrohan | I am not seeing the PATH variable in my .profile file or .bashrc in my home dir, do you know where it may be? Aren't those 2 places where it typically resides |
| 05:17.01 | brlcad | you didn't read those links, did you? :) |
| 05:17.14 | brlcad | doesn't matter if you don't see the PATH variable |
| 05:17.33 | brlcad | you misunderstand how this works, what it is for |
| 05:17.44 | *** join/#brlcad mihaineacsu (~mihaineac@92.81.35.42) |
| 05:17.50 | brlcad | you make it reside where you want it to reside |
| 05:18.08 | brlcad | sometimes someone else does this for you but they certainly don't have to (and in your case, they have not) |
| 05:18.32 | brlcad | you really should read those urls I posted or search the web for some other tutorials |
| 05:19.07 | brlcad | this is basic/faq command line setup understanding that is good to know well |
| 05:19.15 | bjrohan | I have searched the web, there appears to besome differences with Ubuntu (again), for instance, the 1st link shows env | grep PATH |
| 05:19.37 | bjrohan | when I do this in my terminal I get: |
| 05:19.39 | bjrohan | Command 'env' is available in '/usr/bin/env' |
| 05:19.41 | bjrohan | The command could not be located because '/usr/bin' is not included in the PATH environment variable. |
| 05:19.42 | bjrohan | env: command not found |
| 05:19.44 | bjrohan | Command 'grep' is available in '/bin/grep' |
| 05:19.45 | bjrohan | The command could not be located because '/bin' is not included in the PATH environment variable. |
| 05:19.56 | bjrohan | I can see in |
| 05:19.59 | bjrohan | echo $PATH |
| 05:20.01 | bjrohan | /usr/brlcad/bin/dxf-g:/usr/brlcad/bin/dxf-g |
| 05:20.15 | brlcad | "The command could not be located because '/usr/bin' is not included in the PATH environment variable" <-- this means you screwed up PATH earlier |
| 05:20.26 | brlcad | yes, you broke PATH |
| 05:20.35 | bjrohan | crud |
| 05:20.39 | bjrohan | I have a backup :) |
| 05:20.50 | brlcad | you need to undo any edits your made to config files and close that terminal session (in that order) |
| 05:21.15 | bjrohan | The only way I edited it was via the commandline |
| 05:21.21 | brlcad | this is why you need to read and understand a little better what it is you're doing .. these steps are very stateful meaning if you do anything wrong, the future steps will not work right |
| 05:21.26 | bjrohan | I don't know which one it edited |
| 05:21.40 | brlcad | so open a new terminal, echo $PATH |
| 05:22.19 | bjrohan | In a new terminal I get |
| 05:22.21 | bjrohan | echo $PATH |
| 05:22.23 | bjrohan | /home/bjrohan/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/bjrohan/bin:/usr/local/java/jdk*/bin:/home/bjrohan/bin:/usr/local/java/jre*/bin |
| 05:22.34 | brlcad | okay, so then you can "start over" there ;) |
| 05:22.46 | brlcad | close the broken one |
| 05:23.05 | bjrohan | all are closed except for the new one that returned the above |
| 05:23.07 | brlcad | that is a list of directories |
| 05:23.10 | brlcad | you have one more to add |
| 05:23.14 | bjrohan | Okay |
| 05:23.36 | bjrohan | and enter: |
| 05:23.37 | metal-machine | kanzure:yes |
| 05:23.38 | brlcad | re-read the two links and that list of dirs might make more sense now |
| 05:23.38 | bjrohan | export PATH=/usr/brlcad/bin/dxf-g:$PATH |
| 05:23.38 | metal-machine | I have compiled it from source using this http://brlcad.org/wiki/Building_from_SVN |
| 05:23.39 | bjrohan | ? |
| 05:24.02 | kanzure | i don't know if it's compatible with compiling from source |
| 05:24.07 | kanzure | i suspect brlcad would know |
| 05:24.14 | kanzure | also, i am sleeping |
| 05:24.20 | brlcad | too :) |
| 05:24.22 | bjrohan | I do understand the list of directories, those are where exectuables reside so that instead of me typing the entire path, I can simply type the executable, and bash knows where it is |
| 05:24.36 | kanzure | brlcad: his problems sound like path problems, btw |
| 05:24.46 | brlcad | kanzure: metal-machines? |
| 05:24.50 | kanzure | yes |
| 05:25.09 | kanzure | i tried telling him that before but either he didn't listen or it didn't help |
| 05:25.13 | kanzure | but if it didn't help i'm out of ideas |
| 05:25.44 | brlcad | I didn't see him actually share what his problems were other than problems understanding "svn up" |
| 05:26.14 | kanzure | https://github.com/kanzure/python-brlcad/issues/33 |
| 05:28.02 | brlcad | that's very vague |
| 05:28.49 | kanzure | oh i think someone added a hardcoded version check ugh |
| 05:28.52 | *** join/#brlcad gaganjyot (~gaganjyot@124.253.225.90) |
| 05:28.54 | kanzure | that could be the answer |
| 05:28.58 | kanzure | sleeps4real |
| 05:29.04 | brlcad | but you're probably right .. probably built from svn, but hasn't set anything up beyond running "make" .. maybe "make install" |
| 05:30.38 | bjrohan | brlcad: FWIW I have no exisiting .bash_profile as the last link woudl like me to work with |
| 05:43.02 | brlcad | bjrohan: you create that file |
| 05:43.10 | brlcad | just like how you create those lines |
| 05:43.18 | brlcad | reading "man bash" has more details |
