xsect.calc.multi_principal_inertias

xsect.calc.multi_principal_inertias(add, subtract=[])

Calculates the principal area moment of inertias for multiple shapes. Returns an array of shape (2,).

Parameters:

add : list

A list of (x, y) boundary coordinates for shapes included in the cross section. Each set of boundary coordinates should be of the shape (N, 2).

subtract : list

A list of (x, y) boundary coordinates for cut out shapes to be subtracted from the cross section. Each set of boundary coordinates should be of the shape (N, 2).
