Function split_sheet 

pub fn split_sheet(
    model: &mut Model,
    sheet: &Shape,
    by: &Shape,
    tol: Tolerances,
) -> OgeomResult<Built>

A sheet split where another sheet crosses it: the pieces, with history.

sheet and by are each a face, a shell or a compound of those. Each face of sheet is split along the curves where by’s faces cross it, and along by’s edges where they lie in it. Only sheet is split: two sheets are split by each other in two calls, each sheet by the other. The pieces are sewn along the edges they share into one shell, or a compound of shells where they fall apart. Each piece lies on its face’s surface, and the history records each against the face it came from; a face nothing crosses is its own copy. A piece reaching across the seam of a face on a surface of revolution is one face, on that surface turned about its axis so the chart’s join falls outside the piece.

Errors

OgeomError::Construction where either argument is not a sheet; a solid or a half space trims a sheet through common and cut. OgeomError::NotDone where the two sheets overlap on one surface, and as fuse for configurations the splitting refuses.
