Create 2D Setup without Model

billostratum — Sat, 15 Jun 2024 14:30:54 GMT

I am trying to create a setup for 2D toolpaths that use only sketches, without any 3D models.

My script works perfectly in automatically producing all of my toolpaths from templates, using sketch geometry.

My only problem is the annoying warning: "Model: No model selected. All models/solids will be used."

I notice that if I subsequently edit the setup and select either the "Cam Root" component or the "CAM Component:1" component, the warning goes away, with absolutely no impact on my toolpaths.

The docs say that setup.model can be set to an occurrence, but I can't find a way to access occurrences for either of these components.

I've tried using camProd.designRootOccurrence, but that throws an error.

I've read that I should ALWAYS set a model in the setup, which I do when I have bodies, but what to do if I have no bodies (and I don't want to create fake bodies or material bodies simply to avoid this warning).

This must be easy, but in my script I can't find the occurrences that obviously exist for these two components (because the UI allows selection of them).

Any suggestions?

Bill

Note: All of my toolpaths have the same warning, even though they all generated perfectly and, because they are 2D, don't even have the ability to select a model.

Hi @billostratum -San.

I don't know if this will affect you later, but why don't you try setting root.xYConstructionPlane?

# Fusion360API Python script import traceback import adsk.core as core import adsk.fusion as fusion 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 setups: cam.Setups = camObj.setups setupIpt: cam.SetupInput = setups.createInput( cam.OperationTypes.MillingOperation ) # set root.xYConstructionPlane rootOcc: fusion.Occurrence = camObj.designRootOccurrence setupIpt.models = [rootOcc.component.xYConstructionPlane] setup: cam.Setup = setups.add(setupIpt) except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

I think the best way is to create a 3D model.

Thanks for your response. Turns out I was setting .models to the singular designRootOcurrence. Your sample led me to change that to an array. That worked.

setupInput.models = [camProd.designRootOccurrence]
