When the Calculate Shading Factors is turned on in the Building Manager, the progress bar may run continuously without completing. This may occur if the distance between Revit’s internal origin and the model or the distance between the Survey Point and Project Base Point is more than the maximum limit (16km or 10 miles allowed by Revit).
Please review this in your Revit project to ensure that the model is within the limits allowed by Revit. If necessary, relocate the model/Survey Point or Project Base Point to comply with the limit.
