三维螺栓的制作
大家好,不知道哪位大虾有没有做三维螺栓的教程,如果有的话希望能上传上传,谢谢!!!加载以下这个程序就能做你要的螺栓了.

你写的那些,我看不懂.
不加载程度可不可以画三维螺栓? 不加载程序在AutoCAD里难以完成螺栓的制作,加载这个程序非常简单.
具体方法是;
把代码复制到一个记事本文件中,保存(扩展名为LSP)。运行时,用APPLOAD命令加载,用3DLW命令执行。<BR> 那能不能把它改成能画尖尾的螺丝 老胖,想不到你对编程还挺了解的呀~ 胖哥的程序真棒,谢谢!请问可以做反螺纹吗? 太感谢了!!!!! 说了那么多还是不明白呀?我想如果用三维阵列和三维旋转以及分割什么的,我想能做出来吧!只是没有那思路罢了!有哪位大虾有这样的思路吗?谢谢了!!
