I'm hoping to get some help with editing a mesh. I've been attempting to do it myself for a week and I've come to end of my rope so I want to ask if some kind hearted soul out there will do this for me.
I'm making a square cabin so I need a square roof for it. The roof on the RTCivilWarTower01 mesh in the Riften Architecture section is perfect and if I were doing this cabin normally I could simply use it as is. I got this bright idea though that I'm going to make the cabin with glass windows so that you can see into it so it'll be a little more immersive so unfortunately the tower is not usable without editing because you can see the rest of the tower through the windows. Here's a screenshot that shows what I need, everything below the white line can be deleted, if that's possible for someone.

Thank you! Please, help a poor lady modder in distress. I'll be forever grateful and of course, you will get credit for your work on the mod's page.
