Text Extrusion multiple times

[chip.cox]

Is there a limitation that prevents the same profile from being extruded twice or prevents it from being extruded once as a join and again as a cut?  I have a sketch profile of the letter 'B' lets say.  I have a 10mm external dimension square hollow box 4mm thick top wall.  I want to extrude the text so it is raised text on the outside of the box, and inset text on the inside.  I do this in the GUI with two extrude statements.  One as a join with a distance of 12 and one as a cut with a distance of 8.  However, when I do it with the API, I get an invalid argument on the second call to extrude.  

extrudes = root.features.extrudeFeatures

#extrude external box
distance=adsk.core.ValueInput.createByReal(10/10) exExt=extrudes.addSimple(ProBox,distance,adsk.fusion.FeatureOperations.NewBodyFeatureOperation)

#extrude text to create raised text on outside of box
distance=adsk.core.ValueInput.createByReal(12/10)         exTxt=extrudes.addSimple(ProText,distance,adsk.fusion.FeatureOperations.JoinFeatureOperation)

#extrude hex shape to hollow out the box.
distance=adsk.core.ValueInput.createByReal(5/10)                exhex=extrudes.addSimple(ProHex,distance,adsk.fusion.FeatureOperations.CutFeatureOperation)

#extrude character cutting into the top but not getting to the outside.
distance=adsk.core.ValueInput.createByReal(8/10)               exTxt2=extrudes.addSimple(ProText,distance,adsk.fusion.FeatureOperations.CutFeatureOperation)

ui.messageBox('Done')

Hi @chip.cox .

I don't understand what you mean by the question, but I tried.

I tried to simplify the problem by only extruding the letters twice.

From the text, I interpreted the goal to look like the image below.

By setting the direction of extrusion to a negative value the second time, the shape of the image above was obtained.

# Fusion360API Python script

import traceback
import adsk
import adsk.core
import adsk.fusion

def run(context):
    ui = adsk.core.UserInterface.cast(None)
    try:
        app: adsk.core.Application = adsk.core.Application.get()
        ui = app.userInterface
        des: adsk.fusion.Design = app.activeProduct
        root: adsk.fusion.Component = des.rootComponent

        skt: adsk.fusion.Sketch = root.sketches[0]
        ProText: adsk.fusion.SketchText = skt.sketchTexts[0]


        extrudes = root.features.extrudeFeatures

        distance = adsk.core.ValueInput.createByReal(12/10)
        exTxt = extrudes.addSimple(
            ProText,
            distance,
            adsk.fusion.FeatureOperations.JoinFeatureOperation
        )

        distance = adsk.core.ValueInput.createByReal(8/10 * -1)
        exTxt2 = extrudes.addSimple(
            ProText,
            distance,
            adsk.fusion.FeatureOperations.CutFeatureOperation
        )

        ui.messageBox('Done')

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

I have also attached the f3d file I tested of the image.

I got it to work, but I had to add a second sketch profile of the text being extruded.  See the attached F3d below.  I think I read somewhere that the profile is "destroyed" when it's extruded.  That may be what's happening here.
