I have a fully-modelled site in AutoCAD and now need clear sun-path analysis for London on two critical dates: 21 March and 21 June. The study must cover both the existing context and my proposed scheme so I can assess potential overshadowing before we lock the design. Please generate accurate 3D visuals that plot the sun’s movement across each date and illustrate resulting shadows on the building massing and surrounding context. I will supply the .dwg along with location coordinates and any height data you request. Your output should be a set of high-resolution perspective or axonometric renders (static images are fine) that clearly demonstrate how shadow patterns evolve through the day; if you prefer to assemble them into a short turntable or time-lapse clip that’s welcome, but still frames are essential. You are free to use the software you’re most comfortable with—Rhino + Ladybug, SketchUp + V-Ray, Revit Insight, or similar—so long as the geometry remains faithful to my original CAD model. Lighting settings must match true solar data for London (GMT and BST accounted for). Deliverables • Two 3D shadow studies for 21 March: one existing, one proposed • Two 3D shadow studies for 21 June: one existing, one proposed • Source files or scene setup so I can tweak camera angles later Once you receive the model, let me know any clarifications you need and your expected turnaround time.
