Before creating a solar study, prepare a view to display light and shadows.
Consider these recommendations:
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.
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.
