pub fn edges_turn(
model: &Model,
edges: &[Shape],
axis: Vector,
tol: Tolerances,
) -> OgeomResult<f64>Expand description
How a closed walk of edge occurrences turns about axis: twice the
area it encloses projected square to the axis, signed by the right-hand
rule, from points sampled along the edges in traversal order. Positive
for a ring walked counter-clockwise about axis.
§Errors
As the model’s placements and the curves’ evaluation.
