Getting base curve of a window

Hello,
I somehow want to get the base curve of a window as shown in the picture. I need it to create railing in front of window. I saw some related posts but could not get the exact idea. Some were suggesting bounding box and some others. Any suggestions are appreciated.

Hello @shershahbacha9 …something here could probably help…
