I wrote to ANSI, the government organization which oversees IGES and asked if there were a feature-based, parametric IGES translator in the works. I have yet to hear from them. But, when so many translation questions come up in this NG, when so many difficulties arise from lack of a parametric feature translator, I can only conclude there is a need for one. Ignoring the problem won't make it go away! Individual model-to-model solutions are not the answer ~ the whole history of standarization (including IGES) proves that. We need a feature based, parametric standard ~ for exports, for portability between revs, for universal translation!
IGES is a great 2-D standard and it managed to accomodate itself to wireframe, surfaces and splines. But, there's a standards bottle neck, right at the point of features and parametrics, that we have to overcome. We confront it every day and tinker endlessly with it. All I'm saying is that it's time for a basic change in approach, i.e, to solve the problem and move on, to quit the endless diddling with it. We're parametrics people, why be shy about it when it comes to standards that are very broadly and very badly needed! DJ
