The surface finish of 101 is so smooth. Unlike some of the earlier built PLAN ships.

The improved finish is mainly due to two things:

1) The welding was done by smart hand-held arc welders that control for ambient temperature. This helps reduce surface '

2) The plates were precision shaped by Surele SKWB-2500 3D plate-bending machine, which is a world first. See video below. Compared to

Thanks, by78.

I know it is off topics, but does anyone know if the CAD software used by China's ship designers are locally developed or imported ? May be I should post this in the China Ship Building Industry thread.
