New user and learning Chief architect. Navigating around, watching videos, however I can't seem to find learning video of similar situation and what I'm trying to accomplish in my design. Basically, I'm removing a Steel bilco basement door and framing it out with 2x6's , entry door and gable roof. I'm looking to design and create detail drawings including the trusses. Existing walls are 10 foot and entry will be at smaller elevation. I've attached images for reference. Any ideas or suggestions would be greatly appreciated. I'm looking to treat my layouts and design as an addition.
