Finding Child Components

[Anonymous]

I need to access the child components of a component (often the root component). I need to create an object collection of all bodies in the parent and its children to edit the groups

Hello,

The following script would demo how to get all bodies under root. Please let us know if you have other questions.

Thanks,

Marshal

import adsk.core, adsk.fusion, traceback

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface
        
        design = adsk.fusion.Design.cast(app.activeProduct) 
        root = design.rootComponent
        componentNameMap = {}
        componentNameMap[root.name] = root

        for occ in root.allOccurrences:
            subComp = occ.component
            componentNameMap[subComp.name] = subComp
        
        allbodies = adsk.core.ObjectCollection.create()
        for comp in list(componentNameMap.values()):
            for body in comp.bRepBodies:
                allbodies.add(body)
        
        ui.messageBox("Total {} bodies under root component".format(allbodies.count))

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

What am I supposed to do with this root?  I am new to Fusion 360 and really need to see the children of a feature so I know what may change or have issues.  Thanks in advance.
