A novel 3D design software and surface forming inspection interface method for shipbuilding components belongs to the technical field of 3D design of ship surfaces. This method generates NURBS curves based on the surface plate information extracted from the ship segment model data, including the boundary and internal points of the surface plate.

This invention relates to the field of 3D design technology, specifically to a 3D design method, apparatus, and equipment for diversion buildings based on a 3DE platform. According to the diversion project type selected by the user, the corresponding user-defined feature template is called from a pre-built parametric template library. Based on the imported CAD axis, a 3D alignment axis is generated in the 3DE platform. The 3D alignment axis, along with the user-input starting station number, creates multiple positioning points with station number information on the 3D alignment axis. These positioning points serve as spatial anchor points for template instantiation. Based on the 3D alignment axis and the created positioning points, the called user-defined feature template is instantiated into the corresponding positioning point interval on the 3D alignment axis, generating a 3D model instance with structured naming. This ensures that the 3D model construction process is consistent with the engineering segmentation logic of the diversion building, reducing the operational steps and human judgment involved in the model construction process.
