I'm trying to find a good solution to cleanly translate a simple Houdini curve (an open polyline or NURBS curve) for import in AutoCAD. Ideally .dwg format. I could be happy with just getting into Illustrator, but the real challenge is AutoCAD.
To be honest, I've already done it. Export as IGES, then import in AutoCAD using a custom importer:

It's 200$ though, and I'm looking for a free, and (ideally) clean and easy solution.
Shoot!
