The sun path and shadows are available in all 3D views except those that use the Wireframe or Consistent Colors visual style. In 2D views, the sun path is available in floor plans, reflected ceiling plans, elevations, and sections.
For the best display of light and shadows on a project, use 3D views of the building model. Typical plan views, such as floor plans and ceiling plans, do not display many elements in 3D, so no shadows will be cast from these elements. For more information, see Creating an Orthographic 3D View.
To produce solar studies that accurately represent the position of the sun in relation to the project when Project North differs from True North, rotate the view to True North. Alternatively, when producing a Lighting solar study, you can specify the sun’s location relative to the view.
