Python Script - Traverse Assembly & Find "Part Quantity"

[isocam]

Can anybody help?

I have the following Fusion 360 "Python" script...

def traverseAssembly(occurrences, currentLevel, OutputString):
app = adsk.core.Application.get()

ui = app.userInterface

for i in range(0, occurrences.count):
occ: adsk.fusion.Occurrence = occurrences.item(i)

PartQuantity = ????

PartNumber = re.split(' v\d+', occ.name)[0]

PartDescription = occ.component.description

if occ.childOccurrences:
OutputString = traverseAssembly(occ.childOccurrences, currentLevel + 1, OutputString)

return OutputString

Does anybody know how I can get the "PartQuantity"?

Many thanks in advance!

Kind Regards

Darren

If you don't care about where a part exists within the assembly and don't need the structure, here's a simple way to get a list of components and their count.

import adsk.core, adsk.fusion, traceback

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface

        des: adsk.fusion.Design = app.activeProduct
        root = des.rootComponent

        # Create a list of all components and their count.
        partInfos = []
        for comp in des.allComponents:
            refOccs = root.allOccurrencesByComponent(comp)
            partInfos.append([comp.name, comp.description, refOccs.count])

        # Show the results
        for partInfo in partInfos:
            app.log(f'{partInfo[0]}, {partInfo[1]}, {partInfo[2]}')
    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

I tested it on an assembly of mine with multiple levels and got this result. Most of the components don't have a description, so that's why the second field is empty for most of them. It also shows the assemblies, but you could filter assemblies out by checking if the component has any child occurrences and skip that component if it does.
