Exterior 3D Model & Shadow Study

I have floorplans and elevations drawings ready. I can send you CAD files of these plans. I need you to draw a full 3D model of the building, then make shadow study diagrams to see impact on solar access to our neighbour's building on 21st June (hourly diagrams)...
