Determine if document is a "Part" or a "Assembly

[isocam]

Can anybody help?

Is it possible, using a Python script to determine if the document that is opened, is a "Part" or an "Assembly" and show this in a message box?

Eg

The document is a Part

The document is a Assembly

Many thanks in advance!

Hi @isocam .

I interpreted this as determining if Occurrence had a link.

You can use the isReferencedComponent property to determine this.

def run(context):
    ui = adsk.core.UserInterface.cast(None)
    try:
        app :adsk.fusion.Application = adsk.core.Application.get()
        ui = app.userInterface
        des :adsk.fusion.Design = app.activeProduct
        root :adsk.fusion.Component = des.rootComponent

        for occ in root.allOccurrences:
            print(f'{occ.name} : {occ.isReferencedComponent}')

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Fusion doesn't differentiate between a part and an assembly, so it's up to us to define what a part or assembly is.

The pure definition is a part is a component that only contains bodies and not any occurrences.  An assembly is a component that only contains occurrences and no bodies.  Anything else is some kind of a part and assembly hybrid.  Here's some code that determines this.

def determineDocumentType():
    try:
        app = adsk.core.Application.get() 
        ui = app.userInterface 
        design = adsk.fusion.Design.cast(app.activeProduct) 
        root = design.rootComponent 

        if root.occurrences.count > 0 and root.bRepBodies.count > 0:
            ui.messageBox('Document is a hybrid of assembly and part.')
        elif root.occurrences.count > 0 and root.bRepBodies.count == 0:
            ui.messageBox('Document is an assembly.')
        elif root.occurrences.count == 0 and root.bRepBodies.count > 0:
            ui.messageBox('Document is a part.')
        elif root.occurrences.count == 0 and root.bRepBodies.count == 0:
            ui.messageBox('Document is an empty part.')
    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
