| 15:10.43 | mafm | maybe |
| 15:11.29 | mafm | the principle of operation is that you tell libged to do things, then saves data internally, and you can query about what's in there (ged_who, which...)? |
| 15:11.39 | ``Erik | the point of the gsoc effort is to make a geometry interrogator that can later become the next generation editor, right? |
| 15:12.30 | mafm | it could jump that step and try to be directly a ng editor :D |
| 15:12.39 | ``Erik | libged has a fistful of functions that just return info and don't edit anything, so being able to say "show me geometry with region id 42" seems like a logical capability, or "show me all regions made of titanium" |
| 15:13.56 | mafm | hmm |
| 15:13.57 | ``Erik | I know a lot of work around here is 'push the button to convert the Pro/E geometry, then go through and changed r31534 to "steeringwheel.r" |
