| 17:29.53 | Yoshi47 | ok thanks |
| 17:36.41 | brlcad | and I would suggest you not worry too much about naming convention conflicts, so long as the names within a given .g make relative sense |
| 17:37.34 | Yoshi47 | is that because when i do an import i can add a prefix? |
| 17:37.34 | brlcad | dbconcating with a prefix is pretty common practice to help indicate a scope of sorts, and minimizes conflicts |
| 17:37.34 | brlcad | bingo |
| 17:37.50 | Yoshi47 | i figured that out after i changed my names, lol |
| 17:37.56 | Yoshi47 | oh well i learnt |
| 17:38.11 | starseeker | Yoshi47: what license would you want to use? |
| 17:38.20 | Yoshi47 | i did GLV3 |
| 17:38.26 | Yoshi47 | but i don't know the difference |
| 17:38.46 | Yoshi47 | guess i good read, but does it make that much of a diff |
| 17:40.38 | starseeker | BRL-CAD itself is LGPL - Creative Commons is a popular choice |
| 17:41.57 | Yoshi47 | only BSD and GPLv3 were in the list, so LGPL is v3 |
| 17:43.06 | starseeker | Erm |
| 17:43.14 | starseeker | we'll need to expand that list |
| 17:44.05 | starseeker | If you could pick any of the various choices, would you have a preference? (Generally it runs BSD most free to GPL most restricted) |
| 17:46.14 | brlcad | yeah, wow, probably just to stub "something" |
| 17:46.27 | brlcad | gplv3 wouldn't have been top of my list to add first |
| 17:47.48 | brlcad | bsd/mit/apache, cc-by/cc-sa/cc-by-sa, lgpl |
| 17:50.52 | Yoshi47 | i think i would choose the most free |
| 17:51.40 | brlcad | those all allow pretty much any use |
| 17:51.58 | brlcad | something like cc-pd would probably be ideal |
| 17:52.17 | starseeker | brlcad: any idea where that license list lives? |
| 17:52.44 | brlcad | starseeker: pretty good idea it's in the web root for more ;) |
| 17:54.35 | starseeker | is poking there |

| 18:02.56 | Yoshi47 | oh, |
| 18:03.42 | Yoshi47 | i don't know if i asked this before but where is the snapping stuff? is there a plan to make it better? |
| 18:05.16 | Yoshi47 | is there something special to get the grid to draw or is it my color scheme? |
| 18:05.36 | brlcad | presume you mean snap-to-grid? it's on the mged menu, turn on the grid option and then snapping |
| 18:05.52 | brlcad | i believe the grid default is black |
| 18:05.55 | Yoshi47 | kinda, no snap to middle? |
| 18:06.00 | starseeker | will have to look into the more site setup more later |
| 18:06.01 | Yoshi47 | yep i checked it |
| 18:06.40 | Yoshi47 | i guess its hard to do snap to middle with solid objects |
| 18:06.44 | brlcad | there are definitely ideas to make it better -- parametrics and constraints make object snapping a lot easier |
| 18:07.00 | brlcad | it's snaps to the *grid* |
| 18:07.20 | Yoshi47 | ya i just have to get that going, there seems to be a duplication in the menus |
| 18:08.04 | brlcad | yeah, there's quite a bit of duplication, sucks but nobody has stepped up to propose an improved reorg (again, priorities and all) |
| 18:08.18 | Yoshi47 | ah |
| 18:08.55 | Yoshi47 | i have draw grid on but nothing shows up |
| 18:09.15 | brlcad | do you have a black background? |
| 18:09.23 | Yoshi47 | nope on winter theme |
| 18:09.34 | Yoshi47 | and grid is set to black on that |
| 18:09.35 | brlcad | try turning faceplate on |
| 18:09.58 | Yoshi47 | didn't work |
| 18:10.28 | brlcad | ah, default grid is white |
| 18:11.06 | Yoshi47 | even though grid color is 0 0 0 in color schemes |
| 18:11.59 | brlcad | mmm, black is barely visible |
| 18:12.18 | Yoshi47 | i can't see anything |
| 18:12.47 | brlcad | do you see a wireframe? |
| 18:13.02 | brlcad | or have you been rendering/raytracing images into the view with overlay |

| 18:55.50 | brlcad | racetrack-shaped, pill-shaped, stadium-shaped, .. |

| 18:57.50 | brlcad | like two semicircles with equal radii cojoined with parallel lines where the diameter of the circles equals the distance between those parallel lines |
