Modify leads and links after toolpath generation

Issue with Lead and Link Parameters in Toolpath Templates

I'm running into a limitation with toolpath generation that I’m hoping someone can help clarify or offer a workaround for.

The toolpath I'm working with requires specific Lead and Link parameters to be set in order to generate correctly. However, these settings are only available through the Modify Leads and Links menu—they're not accessible directly within the main toolpath form.

The bigger issue is that when I save the toolpath as a template, the customized Lead and Link settings don’t carry over. So when I apply the template later, I have to manually reconfigure those settings each time.

I’m wondering if there’s a way to handle this using the API—perhaps by editing the toolpath links after the toolpath has been generated? Has anyone had success automating this part of the workflow?

Hi @Adam_Popma -San.

I created a sample that switches the RetractionPolicy between “minimum” and “shortest”.

# Fusion360API Python script

import traceback
import adsk.core as core
import adsk.cam as cam

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

        camObj: cam.CAM = app.activeProduct

        setup: cam.Setup = camObj.setups[0]
        ope: cam.Operation = setup.operations[0]
        prm = ope.parameters.itemByName("retractionPolicy")
        if prm.value.value == "minimum":
            prm.value.value = "shortest"
        else:
            prm.value.value = "minimum"

        ui.messageBox(f"RetractionPolicy: {prm.value.value}")

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

I believe he is asking if the leads and links modification that is part of the machining extension is available through the API. I may be mistaken, but I believe your code here only modifies the retraction policy on the "base" toolpath, before any modifications have been applied. And I believe he is applying the modification because the base toolpath parameters are giving an undesired result

Hi @Chris.Barnes.ADSK -san.

I misunderstood.

Although the parameter name here is “entry_type”, I was unable to retrieve it using `cam.Operation.parameters.itemByName(“entry_type”)`.

Can we assume that the parameter currently set to “System Default: isParentStrategyHSM” is not supported?
