Computes lengths of supported topological shapes.

Lengths can be computed for B-Rep edges, B-Rep wires, and polyline sets. Curve-based evaluation is used internally for linear and selected analytic curves. When curve-based evaluation is unavailable, the polygonal triangulation is used if present.

Returns -1 if no measurable length is found for the provided input.
