Writing document user data


I have a two separate programs. The first is a Rhino plugin that writes user data to the document using RhinoCommon, the second one reads this data using OpenNurbs, manipulates it, and then (attempts) to write the manipulated user data back to the 3dm file.

The last bit is where I’m getting hung up. Is it possible to write or edit document user data using OpenNurbs?

Hi Diana; I just spoke with @lleibman about this issue on the phone. Is this a different problem?
