Am attempting to design a basic free standing garage with slab that is 30 x 24. Know that CA forces standard framing but really don't need to get into framing details. Roof plane to be 5/12 with shed roof over 6' left side of garage. Wall height is 10'. don't need a foundation...just a slab inside the garage extending under porch roof. So total slab would be 36 x 24. Used invisible wall to define outside wall of porch but this may not be correct. Roof plane is a struggle, seem to be missing something.
