LOL! "I don't know anything about it, but I'm sure it sucks!"
The good news is that most folks use Pangolin and don't have to worry about exporting to ILDA. Which, once again, is a worthless format. Even so, I have Pangolin and CAN export to ILDA. So what's the deal with this argument??
In all my time playing with lasers I can't think of a single time when I've purchased an ILDA file...
