In Rhino 8 SR16 you could export our gem files as obj nurbs format, using the export selected command.
After updating to the latest Rhino 8 SR18 build, the OBJ Export Plugin no longer exports.
Here is the file for reference, that I was trying to export from:
Exporting objects as NURBS in OBJ Files in Rhino 8 SR18 not working.3dm (597.0 KB)
I updated to the latest SR candidate SR19 and this is still broken.
How can we recommend to our users to download SR16?
