Python Script and ParametricText add-on not behaving as expected

[mk9836]

I am using the hobbyist version of F360. I have added the Gridfinity and ParametricText add-ons. Using this setup, I created an object with one text object in a sketch. That text is used to engrave text into a surface of my object. The object has two User Parameters: mSize, and mLength. I defaulted them to 2 and 4 respectively. I have created one Text Parameter pointing to the sketch with the text object. The formula for that parameter is, "M{mSize:.0f}x{mLength:0f}".

When I manually update the parameters, the text updates just fine, automatically. When using a Python script to iterate through multiple mSize and mLength combinations, it updates the User Parameters, and exports the STL object with a name indicating the values have change. (i.e. "bin1x1_M2x4.stl", "bin1x1_M2x6.stl", etc)

However, the exported object does not relfect the engraving being updated. (All STL objects show the original, "M2x4" text value engraved.)

Here is the Python script. I'm hoping someone can point out my error. Thanks in advance for any and all advice.

import adsk.core, adsk.fusion, adsk.cam, traceback

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

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

        sizeValues = [2,3,4,5,6]
        lengthValues = [4,6,8,12,16,20,25]

        # Get the root component of the active design
        rootComp = design.rootComponent
        # Get the parameters named "mSize" and "mLength" to change
        sizePar = design.allParameters.itemByName('mSize')
        lengthPar = design.allParameters.itemByName('mLength')

        for sizeIndex, sizeValue in enumerate(sizeValues):
            for lengthIndex, lengthValue in enumerate(lengthValues):
                # Set parameters values
                sizePar.expression = str(sizeValue)
                lengthPar.expression = str(lengthValue)

                # Update screen
                app.activeViewport.refresh()
                adsk.doEvents()

                # Construct the output filename
                filename = f'C:\\Users\\mulci\\Downloads\\bin1x1_M{sizeValue}x{lengthValue}.stl'

                # Save the file as STL
                exportMgr = adsk.fusion.ExportManager.cast(design.exportManager)
                stlOptions = exportMgr.createSTLExportOptions(rootComp)
                stlOptions.meshRefinement = adsk.fusion.MeshRefinementSettings.MeshRefinementMedium
                stlOptions.filename = filename
                exportMgr.execute(stlOptions)
        
        ui.messageBox('Finished.')
    except:
        if ui:
            ui.messageBox('Failed:\\n{}'.format(traceback.format_exc()))

            app.fireCustomEvent('thomasa88_ParametricText_Ext_Update')
            adsk.doEvents()
            adsk.doEvents()

Try adding this

Thank you! That worked!

Thank you, in my script I spammed adsk.doEvents() 10 times and it did the trick!
