Stitch

Stitch welds adjacent surfaces along their shared edges. When the resulting shell is closed and manifold, it is automatically promoted to a solid; if it remains open, the result is a shell that can be further thickened or stitched. The tolerance parameter controls how close edges have to be to be considered shared.
