摘　　要：[目的]在使用CATIA创建船体模型的过程中,人为因素较大且工序繁杂。为快速量取船舶型值、采用型值快速化三维建模,给出一种快速、高效的船舶建模设计方法。[方法]基于CAD与CATIA平台,运用面向用户的VB和Java语言,通过自动化接口连接CAD与CATIA模块对二者进行联合二次开发,以量取船舶各型线型值并转换为三维坐标点,快速建立三维型线,生成船体曲面。通过2个算例,验证二次开发程序的效率及可靠性。[结果]结果表明,所编写的二次开发程序可在CAD中将二维型线快速转化为三维型值点,并在CATIA中创建横剖线、纵剖线及半宽水线,实现了快速三维建模的功能。[结论]从2种不同船型的绘制结果可见,使用多平台协同设计技术具有多阶段建模、关联模型的技术特点,可以提高模型质量和绘制效率,极大地方便了用户使用。[Objectives]In the process of creating a hull model using CATIA,human factors are large and the process is complicated.In order to quickly measure the ship's offsets and adopt them to quickly 3D modeling,this paper presents a ship modeling design method,which can improve the efficiency and accuracy of ship modeling.[Methods]Based on the CAD and CATIA platforms,using user-oriented VB and Java languages,the CAD and CATIA modules are connected through an automated interface,and the two are jointly developed to measure offsets of hull form and convert to three-dimensional coordinate points,quickly establish a three-dimensional hull line,and generate a hull surface.Through two examples,verify the efficiency and reliability of the secondary development program.[Results]The results show that the secondary development program written can quickly convert the two-dimensional hull line to three-dimensional offset points in CAD,and create cross-section lines,vertical section lines,half-width waterlines in CATIA to achieve rapid three-dimensional construction modular function.[Conclusions]From the drawing results of the two different ship hull form in this article,it can be seen that the use of multi-platform collaborative design technology in this article has the technical characteristics of multi-stage modeling and related models,and the improvement of model quality and rendering efficiency,which is extremely user-friendly.
