Are you trying to do this interactively in the product or are you trying to write a program to do this? And, what exactly is it you are trying to save? Each of the subassemblies within the main assembly because that would include the parts? Or are you wanting to save each part?

It's still not clear to me. If you have an assembly like this, what STEP files would you expect?

I didn't do a lot of testing, but I think this will do what you want.

def exportSTEP(): try: app: adsk.core.Application = adsk.core.Application.get() ui: adsk.core.UserInterface = app.userInterface design: adsk.fusion.Design = app.activeProduct root = design.rootComponent processedComponents = [] occ: adsk.fusion.Occurrence for occ in root.occurrences: comp = occ.component # Check to see if this component is an assembly. if comp.occurrences.count > 0: found = False checkComp: adsk.fusion.Component for checkComp in processedComponents: if comp == checkComp: found = True break if not found: # Export this occurrence. filename = 'C:/Temp/' + comp.name + '.step' stepExport = design.exportManager.createSTEPExportOptions(filename, comp) design.exportManager.execute(stepExport) processedComponents.append(comp) except: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

What exactly is it you're trying to accomplish? It's still unclear to me what you need because if you only save subassemblies it will be likely you'll miss some parts. There are also cases where some subassemblies will end up being saved more than once because they might exist in other subassemblies.

You can see from the code above, that any component can be saved as a STEP file. It doesn't matter if that component represents the entire assembly, any subassembly, or any part. It's just a matter of determining which components you want to export and that's what is unclear to me.
