将stl导入hfss时出现错误提示

我是刚刚接触hfss，将stl导入hfss时出现错误提示
-e=...: gives the Epsilon value used in comparisons of vertex distances. Default Epsilon = 1e-007
-f=...: gives the Epsilon1 value used in comparisons of normal vectors. Default Epsilon1 = 1e-012
-n: tells the translator use normal vectors saved in STL file instead of calculating them.
希望哪位大侠能帮帮忙

导入路径和文件名都不能有中文
最好是直接在盘符下面，专门建一个英文文件夹来保存sat文件
