Function make_loft_skinned 

pub fn make_loft_skinned(
    model: &mut Model,
    sections: &[Shape],
    tolerance: f64,
    tol: Tolerances,
) -> OgeomResult<Built>

Loft a solid through many closed planar sections, skinned smoothly.

The sections are sampled at matched arc-length fractions from their own traversal starts (aligning those starts is the caller’s authorship), and the skin holds every section to tolerance, between the samples as well as at them: the sampling round a section is refined where the skin misses it. The caps are the first and last sections’ own planes.

A trailing vertex closes the solid on that point instead of a last cap. The skin runs smoothly on to it wherever that wall stays unfolded between the last section and the point; where it would fold through itself (sections turned against each other bend its rows into a figure eight there), the last section reaches the point by the straight cone over it instead, with an edge where the two meet.

Errors

OgeomError::Construction if fewer than two sections, a section is open or not planar; OgeomError::NotDone if the skin cannot reach the tolerance.
