pub fn write_iges(document: &Document, tol: Tolerances) -> OgeomResult<String>Expand description
Write a document’s solids and sheets as an IGES file.
A solid becomes a manifold solid B-rep object (186). A sheet’s faces
become independent trimmed surfaces (144), which a reader sews back into
the sheet they were; a sheet that closes reads back as a solid.
A wire or edge outside every face is wireframe, written as its curve
(an edge’s own, a composite curve (102) of a wire’s edges in the order
the wire walks them) standing independent. A vertex outside every edge
is a point (116) standing independent. The document’s construction
geometry goes out too; write_iges_reported says which items had no
IGES spelling and were left out.
