AttributeError: 'BRepBody' object has no attribute 'bodies'

[victoriaN4VP7]

I'm trying to have the user select a surface that will then be thickened. I'm able to run the code and select a surface but then I get AttributeError: 'BRepBody' object has no attribute 'bodies'. 

import adsk.core, adsk.fusion, traceback

def run(context) :

    try:

        app = adsk.core.Application.get()

        ui  = app.userInterface

        design = app.activeProduct

        SurfaceSel = ui.selectEntity('select a surface', 'SurfaceBodies')

        if SurfaceSel:

            surface = adsk.fusion.BRepBody.cast(SurfaceSel.entity)

            des = adsk.fusion.Design.cast(app.activeProduct)

            root = des.rootComponent

            ui.messageBox('Pass:\n{}'.format(traceback.format_exc()))

        # Create thicken feature

            thickenFeatures = root.features.thickenFeatures

            inputSurfaces = adsk.core.ObjectCollection.create()

            bodies = surface.bodies

            for body in bodies :

                thickenFeatures.add(body)

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

            thickenInput = thickenFeatures.createInput(inputSurfaces, thickness, False,  adsk.fusion.FeatureOperations.NewBodyFeatureOperation)

            thickenFeatures.add(thickenInput)

    except:

        if ui:

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

Hi @victoriaN4VP7 .

Try this.

import adsk.core, adsk.fusion, traceback

def run(context) :
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface
        design = app.activeProduct
       
        SurfaceSel = ui.selectEntity('select a surface', 'SurfaceBodies')
        if SurfaceSel:
            surfaceBody = adsk.fusion.BRepBody.cast(SurfaceSel.entity)
            des = adsk.fusion.Design.cast(app.activeProduct)
            root = des.rootComponent

        # Create thicken feature
            thickenFeatures = root.features.thickenFeatures
            inputSurfaces = adsk.core.ObjectCollection.create()
            for face in surfaceBody.faces:
                inputSurfaces.add(face)
            thickness = adsk.core.ValueInput.createByReal(1.0)
            thickenInput = thickenFeatures.createInput(
                inputSurfaces,
                thickness,
                False,
                adsk.fusion.FeatureOperations.NewBodyFeatureOperation
            )
            thickenFeatures.add(thickenInput)

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