Hi @ho-kou -San.

Since merge commands do not seem to be provided by the API, this sample uses text commands.

# Fusion360API Python script

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

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

        des: fusion.Design = app.activeProduct
        if des.designType == fusion.DesignTypes.ParametricDesignType:
            ui.messageBox("Valid only in direct mode.")
            return

        root: fusion.Component = des.rootComponent

        exec_surface_merge_command(root.bRepBodies[0])

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

def exec_surface_merge_command(
        body: fusion.BRepBody
) -> None:
    
    app: core.Application = core.Application.get()
    ui: core.UserInterface = app.userInterface
    sels: core.Selections = ui.activeSelections

    [sels.add(f) for f in body.faces]

    app.executeTextCommand(u"Commands.Start FusionSurfaceMergeCommand")
    app.executeTextCommand(u'NuCommands.CommitCmd')

In the GUI, the merge command is only available in direct mode, but when I tried it, it worked in parametric mode as well.
However, since nothing appears on the timeline, we felt that this might cause problems, so the sample works only in direct mode.
