This is my first pass at these.
Ramp: know it probably would be better to tighten it up a bit, but this seemed to work. Please let me know if otherwise. The program said something about the wall and door on the existing level (which is below grade if I am reading correctly, but it looks like others have put it where I ended up putting it.
Roof: I didn't run into any big snags here, but please review and let me know if I missed something.
Stair: My top landing ended up enormous to make the rest of the stair work. Probably not the most efficient but it works right?
Please comment, Testing Tuesday! Thanks!
