A full scale mock-up is a good way to get feedback on size, shape, and position.
Getting the design from pixels and bytes to a tangible object can be a major task.
Since I modeled the original in Rhino, I can simply chose stations that will represent the contours of the model and print them out.
(This makes me really appreciate the large format printer)
Here I have bent ¼” rod to match one of the profiles
I will then make a reinforced “spine”to match the longitudinal profile; weld on the sections; and then add structure to stiffen the entire model.
These sorts of models are called “wire bucks”
