The north sought to control their fellow men to the south. The situation was far more complex than muh slaves. The south correctly claimed they could separate from the union just as easily as they had joined it. Legally speaking Lincoln was in the wrong, but was able to exercise the force and will to back up his position.
Anons I had a dream last night that I started 3 twatter accounts to engage in counter ops. It was a very detailed dream.
I don't have a twatter account at all.
3D laser scanning, anon. Once the data is represented as points in 3D space, software creates a polygon model from the cloud of points. The model can then be scaled to any size. There is a similar process called photogrammetry, which uses images and reflection to approximate the 3D shape. It is not as accurate as laser, but can be useful depending on your sculpture, and how much accuracy is really needed.
Dark judge doesn't get banned either. A few years ago Q removed the brakes from Twitter for a few days. Anons may remember. Whitehats are apparently able to insert overrides into the algorithm.
You are asking about two different things in effect. The first is, how to capture the shape of your sculpture and scale it up. That is easily done.
The second is, how to reproduce the larger sculpture in physical form. If you want to be exact, there are boat companies that have gantry CNC machines that can carve something that large. It will not be cheap.
The old school way would be to cut sections from the 3D model every six inches, then scale those up and cut them out. You would have a 20 ft. tall 3D grid that was the correct shape.
