[0003] At present, in the process of three-dimensional modeling lofting of ship pipeline production design, the small-diameter pipes are not lofted, and the length is estimated by the design personnel according to the design drawings to place an order, which has a large difference from the actual demand on site; the order specifications of the supports and the pipe clamps are inconsistent with the demand on site, which leads to a large amount of waste and unnecessary waste in shipbuilding; the structure openings of the cabin access components are all cut by the construction personnel on site by hand, which greatly increases the workload and the work surface aesthetics of the construction personnel on site.
