Very out of practice with rhinocommon, please forgive if I’m missing something obvious. On a rhino compute server, I’m trying to create a File3dm, add some geometry, and then send the serialized json for that file off into the internet:
var file = new File3dm();
var sphere = new Sphere(Plane.WorldXY, 1.5);
var id = file.Objects.AddSphere(sphere);
Console.WriteLine(id);
Console.WriteLine(JsonConvert.SerializeObject(sphere));
Console.WriteLine(JsonConvert.SerializeObject(file));
First console statement gives me the guid, as expected:
3e750df1-4fc4-43a5-9222-a2ad1883379e
Second gives me some familiar json, also expected:

}
And the last one, our problem child, seems to just give me an empty File3dm:

“Objects”, in this case, notably not empty, but giving me an empty object. This is what I get for every geometry type I’ve tried. If I add multiple geometries, I get multiple empty objects.
Is there a step I’m missing, if I want the geometry to exist in the final json object? I’m not above serializing each bit of geometry on its own and building the json string manually, but I don’t think that’s a great move.
