Level of a part in the assembly

joao_mirandaEFM7E — Thu, 17 Oct 2024 08:36:21 GMT

I am developing an API Script to extract a persolalized BOM

But I couth not understand yet how to get Level of a part in the assembly.

Like this:

I've tried this link https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-5a4fa3a6-fa21-11e4-b610-f8b156d7cd97 , but it's not the same.

Hi,

Here you have an updated version of the script which replaces the spaces by the levels as you need them:

import adsk.core, adsk.fusion, traceback # Performs a recursive traversal of an entire assembly structure. def traverseAssembly(occurrences: adsk.fusion.Occurrences, parentLevel: str, inputString: str) -> str: for i in range(0, occurrences.count): occ = occurrences.item(i) currentLevel = f'{parentLevel}{"." if parentLevel else ""}{i+1}' inputString += f'{currentLevel} {occ.name}\n' if occ.childOccurrences: inputString = traverseAssembly(occ.childOccurrences, currentLevel, inputString) return inputString def run(context): ui = None try: app = adsk.core.Application.get() ui = app.userInterface product = app.activeProduct design = adsk.fusion.Design.cast(product) if not design: ui.messageBox('No active Fusion design', 'No Design') return # Get the root component of the active design. rootComp = design.rootComponent # Create the title for the output. resultString = 'Root (' + design.parentDocument.name + ')\n' # Call the recursive function to traverse the assembly and build the output string. resultString = traverseAssembly(rootComp.occurrences.asList, "", resultString) # Display the result. # Write the results to the TEXT COMMANDS window. textPalette = ui.palettes.itemById('TextCommands') if not textPalette.isVisible: textPalette.isVisible = True textPalette.writeText(resultString) except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

My test produces the following result:

Root (Untitled) 1 Component1:1 1.1 Component3:1 1.1.1 Component4:1 1.1.2 Component5:1 2 Component2:1

Thank you.

I tested your code but it give me to many rows

I want something more compact like the image on the right

Hi,

This new version of the function prints single components per level with occurrences count:

def traverseAssembly(occurrences: adsk.fusion.Occurrences, parentLevel: str, inputString: str) -> str: unique_comps = {} for occu in occurrences: unique_comps[occu.component.entityToken] = unique_comps.get(occu.component.entityToken, 0) + 1 for i in range(0, occurrences.count): occ = occurrences.item(i) if occ.component.entityToken in unique_comps: currentLevel = f'{parentLevel}{"." if parentLevel else ""}{i+1}' inputString += f'{currentLevel} {occ.name} {unique_comps[occ.component.entityToken]}\n' if occ.childOccurrences: inputString = traverseAssembly(occ.childOccurrences, currentLevel, inputString) unique_comps.pop(occ.component.entityToken) return inputString

I hope this can help.
