| 07:00.22 | clock_ | Unfortunately the brlcad is completely unusable for an ocassional user |
| 07:00.57 | clock_ | I used to know how to use it 1/2 year ago and now I am trying to use it again and I see I forgot all the elaborate definition |
| 07:01.12 | clock_ | What's the difference between c, g, and r? Which ones permit overlapping and which not? |
| 07:01.22 | clock_ | What is A,B,C,D,H, and V in a cylinder? |
| 07:01.52 | clock_ | The help is also unusable: |
| 07:01.56 | clock_ | mged> help c |
| 07:01.56 | clock_ | Usage: c [-cr] comb_name [boolean_expr] |
| 07:01.56 | clock_ | (create or extend a combination using standard notation) |
| 07:02.19 | clock_ | Doesn't say what a combination is and what properties it has and what is not allowed with combination |
| 07:02.34 | clock_ | THe same for g and r:mged> help r |
| 07:02.34 | clock_ | Usage: r object(s) |
| 07:02.34 | clock_ | (create or append objects to a region) |
| 07:02.34 | clock_ | mged> help g |
| 07:02.34 | clock_ | Usage: g gname object(s) |
| 07:02.36 | clock_ | (create or append object(s) to a group) |
| 07:05.01 | clock_ | The quick reference card PDF takes about 10 seconds to draw a page on 1500MHz CPU so it's rather a slow reference card than a quick reference card |
| 07:26.20 | clock_ | Is it possible to place points in BRL-CAD and then reference them? |
| 07:26.30 | clock_ | For example place points A, B, C, D into space and then say |
| 07:26.38 | clock_ | "connect A and B with cylinder 6mm diameter" |
| 07:26.57 | clock_ | and the same for A and C, A and D, B and C, B and D, C and D |
| 08:02.31 | brlcad | clock_: per your earlier question, you can click in the graphics window to edit a value with the mouse |
| 08:02.37 | brlcad | without typing in values |
| 08:03.34 | brlcad | you select teh edit operation on the edit menu, then middle click in the graphics window using points above and below the center dot to increase/decrease values |
| 08:04.47 | brlcad | main difference between c g and r is syntax, except r also marks the object as a region which has a specific meaning (creates a "part", or solid matter as opposed to just a shape) |
| 08:05.38 | clock_ | brlcad: is it the content of the help stored in the source tarball? |
| 08:07.29 | brlcad | what do you mean? |
| 08:08.12 | brlcad | most of this stuff is covered by the intro to mged guide if that's what you mean |
| 08:10.14 | brlcad | the help for those commands in mged is weak .. they need something like a manpage per command as it's not easy to quantify their use in one line |
| 08:10.50 | brlcad | you really have to grasp the difference between groups/assemblies and regions/parts and combinations before it all makes sense |
| 08:11.51 | brlcad | g creates a group with a simple syntax of just listing objects you want to add, g object a b c d e f will add a b c d e f to a group named object |
| 08:12.35 | brlcad | which is a shorthand for creating a combination of only unions of a b c d e f, i.e. equivalent to c object a u b u c u d u e u f |
| 08:13.49 | brlcad | r does effectively the same thing as g, and can use a similar syntax, but it marks "object" as a region which matters for things like overlaps |
| 08:22.00 | clock_ | and c? |
| 08:22.10 | clock_ | Can I edit the help and improve it? |
| 08:22.25 | clock_ | Can I page and string search in the help output? |
| 08:44.17 | clock_ | Is it possible to change the help and then send a patch? |
| 10:45.32 | clock_ | brlcad: I need to draw a model of lattice truss made of tetrahedral units |
| 10:45.47 | clock_ | The wire is 6mm thick and in some parts 10mm pipe with 1.5mm thick wall |
| 10:45.51 | clock_ | How do I do this efficiently? |
| 10:46.08 | clock_ | Only rotating one wire takes like 15 minutes to get it right |
| 10:46.32 | clock_ | The best would be if I could click 2 points and say connect with wire |
| 12:11.11 | clock_ | brlcad: ? |
| 12:40.51 | ``Erik | heh, he probably went to sleep o.O |
| 13:43.25 | brlcad | heh |
| 13:43.59 | brlcad | clock_: of course you can edit the help and improve it! |
| 13:44.15 | brlcad | for string search, there is already a command, 'apropos' |
| 13:44.58 | brlcad | there isn't currently a pager, though as I mentioned, I have thought that it would be good to move to full blown manpages for the commands |
| 13:46.36 | ``Erik | sleep, row, whatever, just layin' around being lazy... :D *duck* |
| 13:47.28 | clock_ | brlcad: row on the water or on a rowing machine in a gym? |
| 13:47.53 | brlcad | ``Erik: that's your mantra too?! |
| 13:48.02 | brlcad | clock_: on water most days |
| 13:48.10 | ``Erik | gettin' a bit cold to keep that up |
| 13:48.11 | clock_ | must be cold and wet |
| 13:48.12 | brlcad | though it is getting pretty freaking cold at 4am |
| 13:48.16 | clock_ | watery grave ;-) |
| 13:48.25 | ``Erik | about 34f ? |
| 13:48.32 | clock_ | shy stirring water? You should generate electricity! |
| 13:48.38 | brlcad | it was about 38 this morning without the wind |
| 13:48.41 | brlcad | the wind is usually the killer |
| 13:48.44 | clock_ | shy -> why |
| 13:49.33 | ``Erik | no leather jacket, cap, and scarf while rowing? :} |
| 13:49.35 | brlcad | I looked at getting one of those generator motors .. but building the contraption is something I don't quite have time to do right now :) |
| 13:49.57 | clock_ | brlcad: you could support the weak national grid |
| 13:50.40 | brlcad | not too weak around here, but yet ;) |
| 13:50.51 | ``Erik | grids aren't quite national here, and the weakness is in wires being snapped or dug up, not overdrawn |
| 13:51.52 | clock_ | brlcad: I made a new holder for ronja http://images.twibright.com/tns/1f25.html |
| 13:52.28 | clock_ | I think it will be better to not try modeling it because it contains planes tangential to cylinder which I don't know how to make in BRL-CAD |
| 13:52.52 | clock_ | Welding a prototype is more cost-effective option that trying to model it in brl-cad |

| 22:06.14 | test34 | I just installed brlcad and I created a primitive but it doesnt show up in the graphical window (I'm following VolumeII_Introduction_to_MGED.pdf).. any idea what could be wrong? (I tried to create a primitive from the command prompt and from the menus) |
| 22:08.04 | test34 | If I type: l sph1.s, I get V 0 0 0 .. does that mean volume is 0 ? |
| 22:11.46 | test34 | V (0, 0, 0) |

| 22:24.10 | test34 | (ie the radio) |
| 22:24.31 | Twingy | try another primitive |
| 22:25.18 | test34 | hmm it works now.. maybe it was just out of sight? |
| 22:25.49 | Twingy | or your clipping plane prevented you from seeing it |
| 22:25.59 | Twingy | you can always turn clipping off under the menu |
| 22:26.45 | test34 | ok thanks |
