points to construct the radii.- Parameters:
d (float) – Depth of the tapered flange channel section
b (float) – Width of the tapered flange channel section
t_f (float) – Mid-flange thickness of the tapered flange channel section (measured at the point equidistant from the face of the web to the edge of the flange)
t_w (float) – Web thickness of the tapered flange channel section
r_r (float) – Root radius of the tapered flange channel section
r_f (float) – Flange radius of the tapered flange channel section
alpha (float) – Flange angle of the tapered flange channel section in degrees
n_r (int) – Number of points discretising the radii
material (Material) – Material to associate with this geometry

Example
The following example creates a tapered flange channel section with a depth of 10 in, a width of 3.5 in, a mid-flange thickness of 0.575 in, a web thickness of 0.475 in, a root radius of 0.575 in, a flange radius of 0.4 in and a flange angle of 8°, using 16 points to discretise the radii:
from sectionproperties.pre.library import tapered_flange_channel tapered_flange_channel( d=10, b=3.5, t_f=0.575, t_w=0.475, r_r=0.575, r_f=0.4, alpha=8, n_r=16 ).plot_geometry()
