The invention discloses a hull structure modeling closed frame structure boundary identification method and a computer system. The boundary identification method comprises the following steps: setting a rectangular pickup cursor (1) in computer aided design software, and setting a central cross line; the coverage range of the rectangular pickup cursor is adjusted, so that the rectangular pickup cursor covers the closed frame structure, and the center cross line of the rectangular pickup cursor intersects with the boundary line of the closed frame structure; traversing all the graphs in the rectangular pickup cursor, judging whether the traversed graphs meet a boundary selection condition or not, and if the traversed graphs meet the boundary selection condition, selecting the traversed graphs; the boundary selection condition is that the graph intersects with the central cross line of the rectangular pickup cursor, and the graph is the boundary of the grillage. The boundary recognition method and the computer system can quickly and accurately select the boundary lines of the closed frame structure, the operation process is simple and quick, and the design work efficiency can be improved.
本发明公开了一种船体结构建模封闭框架结构边界识别方法和计算机系统。边界识别方法和计算机系统包括:在计算机辅助设计软件中设置矩形拾取光标(1),并设置中心十字交叉线;调节矩形拾取光标的覆盖范围,使得矩形拾取光标涵盖封闭框架结构,矩形拾取光标的中心十字交叉线与封闭框架结构的边界线条相交;遍历矩形拾取光标内的所有图形,判断所遍历到的图形是否满足边界选定条件,若满足边界选定条件,则选定所遍历到的图形;边界选定条件为“图形与矩形拾取光标的中心十字交叉线相交,并且,该图形为板架的边界”。边界识别方法和计算机系统能够快速准确地选定封闭框架结构的边界线条,操作过程简单快捷,有利于提升设计工作效率。
