You can see that the computer made piece is flat.
Below, is how a blacksmith's scroll design appears (and can you see the more three dimensional forms).
... I sought out a design from a contractor friend, The design was modified several times. Because of personal demands, the contractor could not follow through.
A retired Mexican craftsman, who had repaired a badly rusted but beloved large sheet metal sculpture of ours, was persuaded to take on the task. He is a friend one of my employees, who stayed on top... through completion and installation.
The fabrication and installation was done within about three weeks. Seeing how critical the measurements were, I am more convinced how difficult this would be to do at a distance, unless we have a perfect rectangle. Observe the small steps on the end.
Anyway, attached is a photo of the end product. Hope you like it. We do. :-)
