3D Print Structure Button Greyed Out

[misc_engineering]

I am having an issue with the Make/3D Print/STL export feature of Fusion 360. The structure option to choose if the bodies are exported as a single file or separate files for each body is greyed out. This problem is occurring for me across all files. Attached is a screenshot of the 3D print menu opened on a random file showing the structure option stuck on one file and greyed out so it cannot be changed.

I think you are looking to use the Save as Mesh command on the top level assembly instead of the 3D Print command.  This gives the same options and will allow you to use the Structure option.

Using save as mesh is the answer. The structure option is back. Thanks.
