In order to improve the modeling efficiency of cabin insulation in the three-dimensional environment, a secondary development method for rapid modeling of cabin surface insulation and profile insulation is proposed. Based on the AVEVA Marine (AM) platform, PML is applied for the secondary development. By picking up the model to calculate the three-dimensional coordinate points and simplifying the repetitive modeling work and operation flow, the rapid insulation modeling is realized, so as to be convenient for designers to use. The high efficiency of secondary development is verified by comparing the developed rapid insulation modeling function with the original modeling function.
