Is there any (non software)industry consortium that developed any usable software? I wouldn't bet on that effort, and even if it is done perfectly it will still take at least 5 years to match the complexity and feature completeness of AutoCAD. Instead they should force themselves to boycott AutoDesk and use something like FreeCAD and fund the development. Yes, there would be some loss in productivity, still much more probable that it will work out in long term.
