Unfortunately, when I export with a custom origin and Z-Axis remapping, the exported FBX origin tends to end up in an unexpected place. In the above picture, I exported with the highlighted point, and imported the file afterwards. Appears in a similar place in other programs. I would anticipate the mesh to appear at the highlighted position drawn. Is this a bug?
Sad, that you didn’t receive any response.
I just ran into the same problem and I doubt it should work like this.
Export with origin to .3dm does what it should.
Export with origin to fbx (Map Rhino Z to FBX Y - unchecked) does what is expected.
Export with origin to fbx (Map Rhino Z to FBX Y - checked) doesn’t seem to do what is expected.
Expected behavior IMO would be, and can be achieved this way:
Export with origin to 3dm
Reimport 3dm
Export reimported geometry to FBX (Map Rhino Z to FBX Y - checked)
