Custom Shower

[Estrada12]

I am new to this. I am making a custom shower and need help adding a wall above the insert. I have the insert in between 2 walls but need to add like a half wall the drops from the ceiling. Can someone help?

It would be great if you included your .plan file as well as some photos illustrating the problem and some additional info in terms of what you are calling an insert.
