SubD Modeling inside Moi are the scripts of Max Smirnov https://moi3d.com/wiki/MaxScriptArchive
sSplit, sBridge, sSize + SubdD Beta 9 + ... Extrude etc
my ShortCuts are P, B, S, K, E with only these ones you can all modilized in SubD technic!
So you must have only polygons with less 6 edges
better is less 5 and solids !
sSplip is necessary else that will not work! ;)

With your object like this:
If you want to make a result like this as you already have in the posted file:
You could get that by drawing in 2 lines in the side view like this:
Then select the object and run Boolean difference, using the lines as the cutting objects.
Delete these pieces:
Then select these for _sBridge:
Another way is you can select this face:
Run Transform > Rotate > Rotate Axis, click 2 points across the middle of the face for the rotation axis:
After you have placed the axis, type 45 and push Enter to rotate it by 45 degrees:
Repeat on the lower one but with negative 45 (-45) degrees.
