How to swap a sketch from a component to other

[en9y37]

Hi there.

I'm looking for a method to move a sketch from one component to other one via API. The result expected is the same as if drag it manually in the user interface like this:

BEFORE:

AFTER:

Any idea about this?

Thanks in advance

Hi @en9y37 .

I could not find that function in the API.

Not in a good way, but it was possible using text commands.

The following sample creates a new occurrence, sketches and extrudes it.
Then move the sketch to the root component.

# Fusion360API Python script
import traceback
import adsk.fusion
import adsk.core

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

        # create test data
        app.documents.add(adsk.core.DocumentTypes.FusionDesignDocumentType)
        create_test_data()

        # select sketch
        des: adsk.fusion.Design = app.activeProduct
        root: adsk.fusion.Component = des.rootComponent

        fromOcc: adsk.fusion.Occurrence = root.occurrences[-1]
        nativeSketch: adsk.fusion.Sketch = fromOcc.component.sketches[-1]
        targetSketch: adsk.fusion.Sketch = nativeSketch.createForAssemblyContext(fromOcc)

        sels: adsk.core.Selections = ui.activeSelections
        sels.clear()
        sels.add(targetSketch)
        dump_sketch_info(targetSketch, 'before')
        app.activeViewport.fit()
        ui.messageBox('before')

        # exec cut command
        app.executeTextCommand(u'Commands.Start CutCommand')

        # select root component
        sels.clear()
        sels.add(root)

        # exec paste command
        app.executeTextCommand(u'Commands.Start PasteCommand')
        dump_sketch_info(targetSketch, 'after')

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


def dump_sketch_info(skt: adsk.fusion.Sketch, msg: str):
    msgLst = [
        f'**{msg}**',
        f'Component Name : {skt.parentComponent.name}',
    ]

    try:
        msgLst.append(f'entityToken : {skt.entityToken}')
    except:
        msgLst.append( 'error')

    adsk.core.Application.get().log('\n'.join(msgLst))


def create_test_data():
    app: adsk.core.Application = adsk.core.Application.get()
    des: adsk.fusion.Design = app.activeProduct
    root: adsk.fusion.Component = des.rootComponent

    occ: adsk.fusion.Occurrence = root.occurrences.addNewComponent(
        adsk.core.Matrix3D.create()
    )
    comp: adsk.fusion.Component = occ.component

    skt: adsk.fusion.Sketch = comp.sketches.add(comp.xYConstructionPlane)
    skt.sketchCurves.sketchCircles.addByCenterRadius(
        adsk.core.Point3D.create(0,1,2),
        0.5
    )

    extFeats: adsk.fusion.ExtrudeFeatures = comp.features.extrudeFeatures
    extFeats.addSimple(
        skt.profiles[0],
        adsk.core.ValueInput.createByReal(5),
        adsk.fusion.FeatureOperations.NewBodyFeatureOperation
    )

After executing the script, you can confirm that it has been moved by operating undo.

However, since the original sketch object's entityToken property, etc. cannot be obtained, there may be some problems later on.

Hi @kandennti

Thanks for your response. I've given a try and works properly. Nice work around!!!

Unfortunately, the API does not currently support the ability to move a sketch from one component to another.
