Residential apartment complex set incl. plans, elevations, the while works. Shows everything from unit layouts for A1, A2, and A3 types down to the basement levels (-1F). I’ve got full building sections and colored elevations in here too, showing floor-to-floor heights up to 17 floors. Layers are sorted pretty well for walls, columns, stairs, etc.. It’s an older 2000 DWG format so it should open in pretty much any version of AutoCAD without issues. Really comprehensive for looking at high-density housing layouts and structural placement. Includes window and door schedules as well.
