Not trying to step on your toes, John, especially since I largely agree, yet... I managed to hold my tongue during the ongoing jeremiad about G-Code but now this thread has metastasized into statements about information interchange in general. When I was still at NIST, the standing joke was "the wonderful thing about standards is there are so many of them." I'll spare folks a recitation of all the national and international information interchange specification projects in which I've participated or been an observer/commenter. What matters more than the specific interchange specification is that the sending application and the receiving application share an understanding of the information to be interchanged and that the purpose of the interchange is known. If this is so, then many different specifications can be made to work, even some that seem unlikely. If it isn't so, then no specification is likely to please. It might seem that focusing on just geometry would make the problem easy and superficially it does, but the word "geometry" is hopelessly imprecise. And don't get me started on the problems the translator writers have (or introduce) implementing the specifications! Bottom line, be happy if a particular interchange scheme works for you (that's the editorial 'you') but don't be surprised if others disagree with your choice and best give up any hope you may harbor that one specification will win out over all the others. Occasionally, a new activity gets underway, often with great fanfare, to forge the "one ring to bind them all" but no one has succeeded yet and I don't expect success to come in my lifetime. Just my 2 centavos on what was also a nice sunny Tuesday here in G-Burg.
