Abstract:Based on the secondary development of CATIA,a method for automatically generating a ship's three-dimensional solid model based on ship AutoCAD hull line and for calculating the stability is proposed.This method avoids the large amount of manual modeling and calculation time.The VB programming is used to automatically extract the 3D point coordinates of the hull based on the hull line,and the rapid automatic generation of the hull wireframe model,surface model and solid model is realized.The BOM information of the hull is automatically obtained based on the solid model,and the ships hydrostatic force and large inclination stability are automatically calculated.A practical example shows that the method is simple and fast,and its calculation results are more accurate and reliable than the calculation results of traditional methods.It has great engineering application value.
