  有一个方法是通过polygon确定散点来导入，但如果是base angle不为90度的情况呢？通过polygon导入的base angle应该只能确定为90度

  你试一下这个脚本 https://optics.ansys.com/hc/en-us/articles/360034404754-addwaveguide-Script-command

    用这个脚本的话一种理解是用waveguide的四个极点去拟合一个欧拉曲线，这感觉有点过于麻烦了，请问您有这方面的解决方法吗？
    另一种理解就是直接用addwaveguide的命令，这显然是没用的。
    请问您能解答关于addwaveguide的底层语言的问题吗

  这些是目前公开的方法，其它方法用户可以自己开发，比如一层一层的叠加，这在物件库里是有的，因为有些复杂形状过于复杂，可以用这种逐层叠加的方法，每层的宽度发生改变，相当于有倾角。
  不知道你说的底层语言的问题是什么，原理在另外一个链接里面 https://optics.ansys.com/hc/en-us/articles/360034382234-Structures-Waveguide
  你也可以使用第三方软件生成形体然后输入，比如Matlab，Python或者Solid Work等。
