it was extremely educational, especially for the future of my career. it taught me more about elevations, and what the sides of houses look like, and how they are created, and we used past knowledge of units to complete unit 14. The features are doors, ground lines, hidden lines, walls, roof, windows, porch/deck, façade, dimensions, and notes.There are many features of a residential elevation drawing. The most basic is the ground line which as the name suggests is a line that represents the ground and it does not need to be completely flat, then the next easiest line is where the Sidon and concrete meet which is just a straight line. There are also the finished floor and ceiling lines as well as the attic line, all of which are drawn as hidden lines. I had the zsach residence which is pretty easy, I've even already finished all the sides of the elevations and am now just doing the notes and dimensions for all of the houses. And we used past knowledge of units to complete unit 15 especially unit 14. The features are doors, ground lines, hidden lines, walls, roof, windows, porch/deck, façade, finish floor and ceiling lines, sometimes attic lines, dimensions, and notes. The only difference in this was really the sides I did which were north and east and also the type or way the door was made.
