execpt of the "Offset" I do not understand, where it is, I would model it nearly exactly the same.
I can not see how the cutout is made, but I suppose this is a small slot feature (or here a symmetric offset)
As said, maybe I would use a slot, since it is less effort to get it.
But the rest would be the same
You need a cutout feature and a bend feature to what you want. I suggest making a Feature Library from it and you can use anytime.
Here is a video:
Your video is great.
I also think this is the best solution.
But if Solid Edge had a feature to do this it was great. We just need sketch the profile.
