Difficulties Obtaining Path for Lofting

[dozerdroid]

I have written a simple program to loft two lines but I cannot correctly obtain the path for lofting, any assistance most welcome. Creating the planes, sketches and lines work fine however the lines below don't work so I assume I am missing something basic ? Thanks. 

        path1 = rootComp.features.createPath(line1)

        path2 = rootComp.features.createPath(line2)

def createNewComponent(rootComp😞

    allOccs = rootComp.occurrences

    newOcc = allOccs.addNewComponent(adsk.core.Matrix3D.create())

    return newOcc.component

def run(context😞

    ui = None

    try:

        app = adsk.core.Application.get()

        ui  = app.userInterface

        design = app.activeProduct                              # active design

        rootComp = design.rootComponent                         # root component of active design, top level in browser

        hullComponent = createNewComponent(rootComp)            # create a new hull component

        hullComponent.name = "hull"

        planesObj = hullComponent.constructionPlanes            # returns planes object

        xyPlane = hullComponent.xYConstructionPlane             # variable representing the xy plane

        # add construction plane 1, add sketch and line

        planeInput1 = planesObj.createInput()                   # create construction planes

        offsetValue1 = adsk.core.ValueInput.createByReal(1.0)

        planeInput1.setByOffset(xyPlane, offsetValue1)

        plane1 = planesObj.add(planeInput1)                

        plane1.name = "bulkhead 1"

        sketchesObj = hullComponent.sketches                    # returns sketches object

        sketch1 = sketchesObj.add(plane1)

        sketch1.name = "bulkhead 1 sketch 1"                    # create sketch on construction plane

        lines1 = sketch1.sketchCurves.sketchLines

        line1 = lines1.addByTwoPoints(adsk.core.Point3D.create(2.0, 3.0, 0.0),adsk.core.Point3D.create(4.0, 5.0, 0.0))

        # add construction plane 2, add sketch and line

        planeInput2 = planesObj.createInput()

        offsetValue2 = adsk.core.ValueInput.createByReal(3.0)

        planeInput2.setByOffset(xyPlane, offsetValue2)

        plane2 = planesObj.add(planeInput2)                

        plane2.name = "bulkhead 2"

        sketch2 = sketchesObj.add(plane2)

        sketch2.name = "bulkhead 2 sketch 1"                    # create sketch on construction plane

        lines2 = sketch2.sketchCurves.sketchLines

        line2 = lines2.addByTwoPoints(adsk.core.Point3D.create(3.0, 4.0, 0.0),adsk.core.Point3D.create(5.0, 6.0, 0.0))

        # everything above works fine, so lets try a loft between these two lines

        path1 = rootComp.features.createPath(line1)

        path2 = rootComp.features.createPath(line2)

        #I also tried as below ?

        #path1 = adsk.fusion.Path.create(line1, adsk.fusion.ChainedCurveOptions.noChainedCurves)

        #path2 = adsk.fusion.Path.create(line2, adsk.fusion.ChainedCurveOptions.noChainedCurves)

            # create a surface loft feature between the two lines

        new_feature = adsk.fusion.FeatureOperations.NewBodyFeatureOperation

        loft_features = rootComp.features.loftFeatures

        loft_input = loft_features.createInput(new_feature)

        loft_sections = loft_input.loftSections

        loft_sections.add(path1)

        loft_sections.add(path2)

        loft_features.add(loft_input)

Hi @dozerdroid .

Since we are creating a sketch with a new occurrence, we will need to get the createPath from the same features as the sketch.

・・・
        # everything above works fine, so lets try a loft between these two lines
        
        # path1 = rootComp.features.createPath(line1)
        # path2 = rootComp.features.createPath(line2)
        path1 = hullComponent.features.createPath(line1)
        path2 = hullComponent.features.createPath(line2)

・・・

The same will be true for loftFeatures.

        # create a surface loft feature between the two lines
 
        new_feature = adsk.fusion.FeatureOperations.NewBodyFeatureOperation
        # loft_features = rootComp.features.loftFeatures
        loft_features = hullComponent.features.loftFeatures
        loft_input = loft_features.createInput(new_feature)

Thank you for your assistance.
