トリム前後で同一の線と判断したい2

こちらの続きです。
トリム前後で同一の線と判断したい1 - C#ATIA

早速、属性が引き継がれるんじゃないかな？テストコード。

# Fusion360API Python script

import traceback

            return '\n'.join(lst)

    # *********
    msg = '-------\n'
    msg += f'classType | {sktEnt.classType()}\n'
    msg += f'isVisible | {isVisible(sktEnt)}\n'
    msg += f'token | {getToken(sktEnt)}\n'
    msg += f'attrs | \n{getAttrsStr(sktEnt)}\n'

    adsk.core.Application.get().log(msg)

結果はこちら。

ふぅ、結論無理。
