Example
The following example creates a monosymmetric I section with a depth of 200 mm, a top flange width of 50 mm, a top flange thickness of 12 mm, a bottom flange width of 130 mm, a bottom flange thickness of 8 mm, a web thickness of 6 mm and a root radius of 8 mm, using 16 points to discretise the root radius:
from sectionproperties.pre.library import mono_i_section mono_i_section( d=200, b_t=50, b_b=130, t_ft=12, t_fb=8, t_w=6, r=8, n_r=16 ).plot_geometry()
