My drawings will include:
1. detail scaled elevations, perspecive in 3D format Yes garage is 2 feet lower than first floor. It is already accounted for if I show it on the 3D view. Yes I know I need to add the stairs as well as actual floor. My first floor is actually floating because it is off ground and I haven't add the floor yet.
2. detail scaled layout, also in 3D format, considering the height of each floor, ceiling, doors, windows, curve, wall etc, etc.
3. Building exterior/interior look and furnishing.
I will not include:
1. Any mechanical/electrical/structural/plumbing design since it's simply beyond my ability and my purpose. At the end of the day those are hide behind the wall and I don't really care. The engineer can figure those out for me.
To simplify above, I'm more like an designer, not an engineer.
