Hi Jo Ann
If you see the overhead view in my first post, and the front elevation, what you can see is that there is no wall there. In that section, the hip roof at the second story continues down to the first story, where it intersects the gable roof over the stone portion of the house. So, there is no exterior wall in that section. On the side of the house, there is a triangular shaped wall which follows the roofline down. I would think the way to do this is to make the wall section a knee wall, or use the extend roof down tool. I will follow shortly with a pic from my phone.
