The following are known issues associated with the Solar Radiation feature.
- Solar radiation values are less accurate at higher latitudes and low sun angles (early morning or late afternoon times of the day).
- Imported mass faces are included in solar radiation analysis even when the import category is made invisible. As a workaround, delete the imported faces in the model before analysis.
- Selecting faces from multiple 3D views of the same document is not allowed.
- While in selection mode, box selection clears all existing selected faces.
- Gridlines in analysis results do not directly correspond to analysis locations. To see analysis locations, use a text marker type of analysis display style.
- Undo does not clear analysis results. If you need to clean analysis results, select it in the Vasari view and click the Delete button.
- Analysis legend may disappear after multiple analysis are performed on different selected faces. One workaround is to change display units to another unit and back to the original unit.
- Analysis results may disappear after a mass is modified and an analysis is performed again. A workaround is to click the Analyze button to refresh analysis results.
- When a mass is modified, analysis results update only on the active view. If you have other views with analysis results, you will need to activate those other views, and click the Analyze button on the Solar Radiation dialog to update those views.
- Showing analysis results may affect how shadows are displayed. You may need to refresh the active Vasari view to display shadows properly.
- Solar Radiation sometimes flips the normals on open surfaces causing analysis results to be the opposite of what is expected. To mitigate this, mirror the surface.
- Solar Radiation does not work on an energy model in "Show Mass Zones" display style.
- Solar Radiation can be used in "Show Mass Surfaces" display styles, however, the results are coincident with the energy model surfaces, and may not read clearly. To mitigate this issue and see the effects of solar radiation on the energy model surfaces, make the energy model surfaces transparent. Note that Solar Radiation treats all surfaces as thought they are opaque, however transparent surfaces do not cast or receive shadows.
