loft a surface from 3d splines

[franck.gressier]

Hello,

I am trying with the API to make a surface using the loft feature.

I have a sketc3dSplines where I have a bunch of 3d splines.

If this is in the root component then this peace of script works:

import adsk.core, adsk.fusion, traceback

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui = app.userInterface
        design = app.activeProduct
        comp = design.activeComponent
        # ui.messageBox(comp.name)
        sketches = comp.sketches
        splines3d = sketches[0].sketchCurves.sketchFittedSplines

        features = comp.features
        loftFeats = features.loftFeatures
        loftInput = loftFeats.createInput(adsk.fusion.FeatureOperations.NewBodyFeatureOperation)
        loftInput.isSolid = False
        loftSectionsObj = loftInput.loftSections

        for courbe in splines3d:
            openProfile = adsk.fusion.Path.create(courbe, adsk.fusion.ChainedCurveOptions.noChainedCurves)
            loftSectionsObj.add(openProfile)

        # Create loft feature
        loftFeats.add(loftInput)



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

but if it is in a separate component then the adsk.fusion.Path.create fails.

It says InternelValidationError:utils::getObjectPath ...

Bug ?

can you help ?
