| 02:49.42 | brlcad | where'd the shuttle model come from? |
| 02:58.05 | IriX64 | some site i found on the web, shall i search again, i can probably find it |
| 03:19.11 | brlcad | nah, just curious |
| 03:19.20 | brlcad | you converted from dxf or something i presume |
| 03:19.32 | brlcad | looks like there's multiple top-level objects being displayed/rendered |
| 03:24.06 | IriX64 | yes from a dxf |
| 03:26.28 | IriX64 | http://www.escape.de/~quincunx/dxf/ this site |
| 03:26.52 | IriX64 | this one is a dxf |
| 03:46.00 | brlcad | you can't directly convert a dwg |
| 03:46.07 | brlcad | that's a 2D file format, not solid geometry |
| 03:46.25 | brlcad | if you can get someone to turn that into a dxf, then there is some potential import paths |
| 03:50.33 | IriX64 | mmm ty |
| 04:00.53 | deltazap | brlcad: how good is the converter at working with dxf's? |
| 04:01.40 | brlcad | it's not fully tested with several of the 2D dxf types, but it is a fairly comprehensive converter |
| 04:02.27 | brlcad | it should even bring in the 2D items now using the cvs head version |
| 04:02.31 | brlcad | as sketch objects |
| 04:06.20 | deltazap | i learned today how powerful the mged editing functions are |
| 04:07.29 | deltazap | much better than trying to click and drag things around |
| 04:10.59 | IriX64 | theres something to be said about a good command line |
| 04:11.43 | IriX64 | not to mention that beautiful "exec" anything :) |
| 04:12.30 | deltazap | it forces you to know the geometry |
| 04:12.47 | IriX64 | yes, a good thing |
| 04:14.25 | brlcad | deltazap: ahh, excellent.. that's one of several karmatic delight moments that come with experience that just can't be easily explained |
| 04:15.21 | brlcad | akin to explaining the true flexibility and power of the unix command prompt to a new user |

| 16:49.16 | deltazap | replacing a primative with a region |
| 16:49.30 | deltazap | for instance, i'm trying to model something built from 80/20 |
| 16:50.04 | deltazap | so, i created the structure using arb8s and then i was going to go back and replace them with the 8020 models |
| 16:51.19 | deltazap | er...8020 region |
| 16:52.19 | deltazap | i'm guessing that i'd have to make the 8020 region the same length of the primative that i want to replace |
| 17:15.09 | ``Erik | erm, regions are built out of combinations and primitives... |
| 17:21.24 | deltazap | yes yes, but i want to replace an existing primitive in the model with a newly created region |
| 17:22.33 | ``Erik | erm, but you NEED those primitives to build the new region... "r thing.r part1.s u part2.s", then you can "B thing.r" |
| 17:22.56 | ``Erik | (or d part1.s;d part2.s) |
| 17:23.03 | deltazap | i was going to use a new set a primatives for the region, then swap out that primative with the new region |
| 17:23.39 | ``Erik | erm, so you're going to ... clone primitives... to build the region... then delete the old primitives? |
| 17:25.47 | deltazap | i wouldn't need to clone them |
| 17:27.08 | ``Erik | one of us doens't understand what you're trying to do :) (probably me) |

| 18:34.04 | brlcad | instancing in this case is very much like a pointer, just referencing something else instead of having actual unique objects (and *much* more importantly, unique regions) |

| 18:34.30 | ``Erik | so jsut two regions using the same primitive? |
| 18:34.40 | brlcad | personally, I don't think there's anything wrong with modelling left/right half if that's what they wanted to do |
| 18:34.51 | brlcad | the problem is that other tools make assumptions |
| 18:34.52 | ``Erik | or something of that nature? a reference count would solve it? |
| 18:35.22 | brlcad | it's not so easy because it is perfectly find to "instance" some things |
| 18:35.26 | brlcad | s/find/fine/ |

| 18:36.39 | ``Erik | hm, ccb fodder? |
| 18:36.48 | brlcad | it's like telling modellers that they shouldn't use a half-space to slice objects |
| 18:37.38 | brlcad | the only problem with using half-spaces is that they are unoptimized, so it kills ray-trace performance .. as a modelling tool, it's rather straight-forward and understandable -- just as understandable as just "flipping" the left half a vehicle and calling it done |
| 18:38.07 | brlcad | if clone were completed, it would solve the "reference" problem |
| 18:38.09 | ``Erik | *nod* I know in lightwave tutorials, I saw the 'mirror' approach being "normal" |

| 19:45.04 | brlcad | matrix selection and oed are identical in that you specify the right and left half (hence the two dialogs) |
| 19:45.53 | brlcad | if you wanted to apply a matrix edit to the instance of "some" in the object "path", it would be oed /path/to some/primitive |
