Create an architectural sightline analysis diagram overlaid on the provided black and white CAD site plan. Keep the original layout visible as the background.
Visual Scope: Add purple, semi-transparent view cones projecting from key vantage points on the surrounding roads towards the central complex. Differentiate view angles (e.g., 60°, 120°).
Sightlines: Draw specific vectors/lines indicating lines of sight. Use solid purple lines for clear views and red lines for obstructed views. Label obstructions clearly with text like "Blocked by Podium" or "Blocked by Tree".
Markers: Place numbered blue circles at the origin of each viewpoint. Mark specific targets in the center.
Style: Professional urban planning analysis aesthetic, vector graphic style, technical annotations, and a legend sidebar explaining the symbols.
