In the process of cabin insulation modeling, the application of AM native modeling function is cumbersome and inefficient, and the modeling results are not ideal. In order to improve the modeling efficiency of cabin insulation in three-dimensional environment, a secondary development method for cabin curved surface insulation and profile insulation rapid modeling was proposed. Based on Aveva Marine platform, PML a programmable macro language was used for secondary development. The three-dimensional coordinate points are calculated by picking up the model, which simplified the repetitive modeling work and operation process, and realized rapid insulation modeling for the convenience of designers. Finally, the high efficiency of the secondary development is verified by comparing the developed insulation fast modeling function with the original modeling function.
