We design and build interactive environments. We use Rhino3D/Grasshopper to draw and Max/MSP/Supercollider to create soundscapes, so Iannix would be an ideal link to have a more direct connection between the two.
The developers of Rhino created OpenNurbs to provide software developers the tools to accurately transfer 3-D geometry between applications. Would you be interested in allowing Iannix to read OpenNurbs files? http://www.opennurbs.org/
