Problem turning steel beam into an arc

Good morning I’m posting this comment on the forum because I’m developing a script that generates bows and turns them into a kind of steel beam family, but I don’t know what I’m doing wrong. The script reads the excel and calculates the arcs correctly the problem is drawing the steel structure. thank you for your helpprueba arco.dyn (54.8 KB) prueba de arco.xlsx (11.5 KB)
