I have another question:
I created one Rhino object with UserString data.
I save the object to 3dm file.
I open the file again, then UserString data of object is missing.
If I want to save the UserString data, how can I do?
coding write UserString data on CRhinoUtilityPlugIn::WriteDocument()?
I don’t seem to be able to access the issue on myjetbrains, and I can’t seem to spot what the solution is in your sample c++ code.
Can you please advise further on how to address this issue using c# and rhinocommon?
I’ve seen also that user strings aren’t being set when using modify user attributes method.
I searched harder through my emails (as I did recall encountering this in the past).
Adding a line such as atts.LayerIndex = atts.LayerIndex; ensures Rhino recognizes that the attributes have been modified.
