Failed to select a cylinder-face as geometry for a drill operation

[maurizio_manzi]

Hello,
I create a drill operation and select my cylinder-Face as geometry (drill position),

but in the line "selection = cadcontours.getCurveSelections()" I get an error message:

"AttributeError: 'CadObjectParameterValue' object has no attribute 'getCurveSelections'"

Code:

# drillFace is my cylinder-face (I can select it manually in the operation)

operationInput = setup.operations.createInput('drill')

operationInput.tool = toolDrill

op_drill = setup.operations.add(operationInput

op_drill.parameters.itemByName('holeMode').expression = "'selection-faces'"

cadcontours: adsk.cam.CadContours2dParameterValue = op_drill.parameters.itemByName('holeFaces').value

selection = cadcontours.getCurveSelections() # <<<--- Error see below

faceContourSel: adsk.cam.FaceContourSelection = selection.createNewFaceContourSelection()

contour selection

faceContourSel.inputGeometry = [drillFace]

cadcontours.applyCurveSelections(selection)

# ERROR:

#selection = cadcontours.getCurveSelections()

#AttributeError: 'CadObjectParameterValue' object has no attribute 'getCurveSelections'

Best regards

Hi @maurizio_manzi .

"op_drill.parameters.itemByName('holeFaces').value" is "CadObjectParameterValue" instead of "CadContours2dParameterValue".

Therefore, it must be done this way.

・・・
        operationInput = setup.operations.createInput('drill')
        operationInput.tool = toolDrill
        op_drill = setup.operations.add(operationInput)
        op_drill.parameters.itemByName('holeMode').expression = "'selection-faces'"
        # cadcontours: adsk.cam.CadContours2dParameterValue = op_drill.parameters.itemByName('holeFaces').value
        cadcontours: adsk.cam.CadObjectParameterValue = op_drill.parameters.itemByName('holeFaces').value
        # selection = cadcontours.getCurveSelections() # <<<--- Error see below
        # faceContourSel: adsk.cam.FaceContourSelection = selection.createNewFaceContourSelection()
        # contour selection
        # faceContourSel.inputGeometry = [drillFace]
        # cadcontours.applyCurveSelections(selection)
        cadcontours.value = [drillFace]
・・・

Thank you very much for help.
I create the cylinder surface for the drill operation as a revolve:

# Create surface as rotation:

revolves = occComp.features.revolveFeatures

revInput = revolves.createInput(profile, axis, adsk.fusion.FeatureOperations.NewBodyFeatureOperation)

angle = adsk.core.ValueInput.createByReal(math.pi*2)

revInput.setAngleExtent(False, angle)

revInput.isSolid = False

ext = revolves.add(revInput)

Now I try to use the revolve ("ext") as surface for the drill operation:

drillFace = ext # Revolve as Face for drill operation

operationInput = setup.operations.createInput('drill')

operationInput.tool = toolDrill

op_drill = setup.operations.add(operationInput) # Add Operation

op_drill.parameters.itemByName('holeMode').expression = "'selection-faces'"

cadcontours: adsk.cam.CadObjectParameterValue = op_drill.parameters.itemByName('holeFaces').value

cadcontours.value = [drillFace]

But I get in the operation an error message (see pic below).

I think, I can't use directly the revolve as face for the drill operation.
How can I get a valid face from my revolve operation ?

Best regards

@maurizio_manzi .

As with all questions, it takes too much time to reproduce the same condition rather than looking for the cause.
Could you please attach the f3d file?

@maurizio_manzi .

It should be a BRepFace listing, not a RevolveFeature.

・・・
        # drillFace = ext # Revolve as Face for drill operation
        drillFaces = [f for f in ext.bodies[0].faces]
・・・
        # cadcontours.value = [drillFace]
        cadcontours.value = drillFaces
・・・

There may be other causes, but we cannot be sure without seeing the data.

Use this one because the indentation is broken.

How can I create this dump myself ?

@maurizio_manzi .

Thanks for the data.

I gave up because I don't know what "profile" and "axis" are.

Hello,
It works fine, with:

drillFaces = [f for f in ext.bodies[0].faces]
・・・
        # cadcontours.value = [drillFace]
        cadcontours.value = drillFaces

 Thank you very much.

How can I see this dump in my VS-code ?

Best regards
Maurizio
