Is there a way to model rooftop solar obstructions in Ecotect, in order to determine where the shade will be throughout the year for a given obstruction and then export this as a "keep-out" area into AutoCAD? I think it would be a perimeter around an obstruction showing where you shouldn't mount PV modules. Without something like this, I spend a lot of time calculating shadow lengths at various times of the day throughout the year and mapping out my own shading keep-out areas.
I would think you could export this perimeter as a .dwg and import it into AutoCAD to work around. Is something like this possible?
