Architectural CAD Stair Modification

I already have a complete architectural plan in CAD and only need one focused change—the staircase. The current steps must be re-worked to match new dimensions and layout notes as shown in the enclosed drawing (rise, run, landing depth, and head-clearance adjustments).

All other elements in the drawing stay as is; no walls, doors, or furniture need touching. Please work directly in the existing layers, keep line-weights and annotation styles consistent, and cloud or colour-code the edits so they are easy to review.

Deliverables:
• Updated DWG file with the modified staircase based on the enclosed drawing
• A clean PDF print set showing the revision clouds
• One round of minor tweaks after my review

If you have solid AutoCAD (or compatible) skills and can turn this around quickly, let’s get started.
