|In case when a shape still has some unsewed faces or edges after sewing, it is possible to use local sewing with a greater tolerance.|
|Local sewing is especially good for open shells. |
Local sewing allows to sew a hole in one part of the shape and to keep a required hole smaller than the specified working tolerance for local sewing. Local sewing is much faster than sewing on the whole shape.
All pre-existing connections of the whole shape are kept after local sewing.
