Thank you very much for the suggestion LawB10. Not exactly oriented like I am trying to design it. It needs to turn 90 degrees with the higher part of the shed roof (4/12 pitch) intersecting with the gable roof (12/12 pitch). To help clarify the existing gable roof ridge runs east/west. I want the shed roof to run north/south or 90 degrees to the gable roof ridge.
In other words, I am trying to draw the beginning (or lowest part of the shed roof) at the far right exterior wall and then climbing/uphill towards the ridgeline (which is running perpendicular to the direction of the shed roof) of the gable roof. I am expecting the actual point the shed and the gable will touch each other will end up about 1/2 to 2/3 up the existing gable roof plane.
Hope I haven't confused what I am looking to draw. So you know I have spent quite a few hours reading forum articles, help articles and searching for a solution to no avail. I don't want folks to think I am being lazy to look up the answer.
Thanks,
