Pipeline follow-up three-dimensional layout design method

The invention discloses a pipeline follow-up three-dimensional layout design method. The method comprises the following steps: S1, 3D modeling; s2, performing statistics on actual interface information of equipment, valves, instruments and valves in the hydrogen refueling station, and sequentially constructing an interface type table and a matching relation table; s3, establishing interface control points respectively corresponding to equipment, valves, instruments and valves in the hydrogen refueling station 3D model; s4, a pipeline is drawn in the hydrogen refueling station 3D model, and path control points are arranged on the path of the pipeline; and S5, inserting inserts into the pipeline paths of the hydrogen refueling station 3D model, adjusting the interface control points, and automatically generating the pipeline paths again. According to the pipeline follow-up three-dimensional layout design method, the pipeline is automatically generated and can automatically change along with movement of the equi
