pub fn merge_same_surface_faces_excluding(
solid: &BrepSolid,
tolerance: f64,
keep_unmerged: &[String],
) -> Result<BrepSolid, KernelRefusal>Expand description
Like merge_same_surface_faces, but any face whose name CONTAINS one of
keep_unmerged is pinned: it never merges with a coplanar/cosurface
neighbour and is emitted unchanged, while every other face merges exactly as
merge_same_surface_faces would. An empty keep_unmerged is identical to
the plain call.
