• fredflyn-Remove- at TakeThisOuTpacbell.net asks:

  As an architect I would like to find a sunangle program which I can import into an autocad drawing in aerial or plan view to overlay (transparent) a home plan design to show clients the actual path of the sun for their location. Is there such a program ?
