Parametric (and still simplified) modelling of the "Arc Majeur" artwork located in Belgium on the E411 motorway, a few km from the place where I live. It is made of 250 tons of CORTEN (weathering) steel and owering at 60m. More information here: http://www.arcmajeur.com/en/
In math a major arc is the longest arc between two points on a circle (i.e more than 180 degrees thus) about 205 degrees in my estimation.
Not totally sure about exact dimensions but can be tuned as parameter in the OpenScad file. Radius looks about 30m and section is square (edge=2.25m)
Using a bit exagerated (4m instead of 2.25) gives better looking structure and result in better quality in small size.
Thanks to Tim chickenchuck040 for providing the arc primitive https://www.thingiverse.com/chickenchuck040/about
More exact figures welcome (some onging requests)
