How to edit the values of the MachineAvoidGroups automatically inserted by Fusion

Hello,
in this example:
https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-a0cfe144-1a0f-4109-9125-8fbd3176ceed
are only the munually groups in use:

# Get the MachineAvoidGroups object from the CadFaceGroups cad object. This object manages the list of mutually exclusive groups.
        _machineAvoidGroups = surfaceGroupsParam.getMachineAvoidGroups()

Neither in the example nor in the API documentation could I find how to change the mode for the groups automatically inserted by Fusion.

Best regards
Maurizio

this works good for me:

def FlatMillFaces(tool: int, machine, faces, sheet: adsk.cam.Setup): if len(faces) > 0: edgelist = [] for items in faces: items: adsk.fusion.BRepFace for loop in items.loops: if loop.isOuter: for e in loop.edges: edgelist.append(e) tool = Utility.ToolGetter(machine, tool) sheets = sheet.parentSetup flatInput: adsk.cam.OperationInput = sheets.operations.createInput("flat") flatInput.tool = tool preset = tool.presets.itemsByName("Default preset") flatInput.toolPreset = preset[0] flatInput.displayName = f'PocketMill {tool.parameters.itemByName("tool_description").value.value}' #flatInput.parameters.itemByName("tool_coolant").value.value = "disabled" flatInput.parameters.itemByName("useRestMachining").value.value = False flatInput.parameters.itemByName("restMaterialSource").value.value = "job" flatInput.parameters.itemByName("topHeight_mode").value.value = "from stock top" flatInput.parameters.itemByName("topHeight_offset").expression = "0 in" #flatInput.parameters.itemByName("topHeight_checkStockTop").value.value = True flatOp: adsk.cam.Operation = sheets.operations.add(flatInput) flatOp.parameters.itemByName("boundaryMode").value.value = "none" flatOp.parameters.itemByName("direction").value.value = "both ways" flatOp.parameters.itemByName("transitionType").value.value = "curve" surfaceGroupsParam: adsk.cam.CadMachineAvoidGroupsParameterValue = flatOp.parameters.itemByName('checkSurfaceSelectionSets').value machineAvoidGroups = surfaceGroupsParam.getMachineAvoidGroups() ModelGroup = machineAvoidGroups.defaultGroup(1) ModelGroup.machineMode = adsk.cam.MachiningMode.Avoid_MachiningMode machineAvoidGroup: adsk.cam.MachineAvoidDirectSelection = machineAvoidGroups.createNewMachineAvoidDirectSelectionGroup() machineAvoidGroup.machineMode = adsk.cam.MachiningMode.Machine_MachiningMode machineAvoidGroup.inputGeometry = faces surfaceGroupsParam.applyMachineAvoidGroups(machineAvoidGroups)

Hello,

ModelGroup = machineAvoidGroups.defaultGroup(1)
        ModelGroup.machineMode = adsk.cam.MachiningMode.Avoid_MachiningMode

don't works.
The mode remain even at machining.
It change not to avoid.
Best regards
Maurizio
