Staircase Section Drawing (AutoCAD)

I have an assignment that calls for a full-blown, academically annotated cross-section through a staircase at 1:50. You will start from a clean sheet in AutoCAD and translate everything you see in my source material into a neat, precise DWG, then export a matching PDF ready for print.

What I will send you on day one:
• a high-resolution photo of the assignment sheet showing every dimension already laid out
• the lecture slide pack that explains the construction sequence and detailing conventions we must follow
• a simple floor-plan sketch that locks the stair into position and confirms floor-to-floor levels

What you will build:
• an academically formatted section that carries the full set of labels, dimensions, scale graphics, and title block
• clear representation of step sizes, landings, handrails, required headroom, plus the surrounding floor and ceiling layers, wall build-ups, finishes, foundation line, structural supports, and how the stair meets the roof zone if shown in the notes

Acceptance: the PDF must plot at true 1:50, every dimension from the brief must check out, and the DWG should open error-free in AutoCAD 2018 or later with layers named logically. When those boxes tick green, the job is done.
