Export vs Save As in Fusion 360 (What's the difference?)
You would like to know the difference between File > Export and File > Save As in Fusion 360.
File > Export uses 'cloud' translation. The processing is done on Autodesk servers and does not consume any of your local CPU. Export also includes the choice of the following file extensions:
File > Save As lets you create a copy of the file. Choose a name and location. Note: The file must be saved before you can use Save As.
Save as STL
Right-click on a component in the Browser > Save as STL
Save as STL will let you save as an STL (Standard Tessellation Language) file. This process is done client-side (using your local CPU), while File > Export > STL will use the cloud (Autodesk servers) and may take longer to process. Save as STL also gives you the option to define the refinement or format.
