请问利用solidworks作的模型导入fdtd里面以后,发现没有位置信息,这个怎么处理


#1

就是将模型导入以后,无法获取这个模型的位置信息


#2

这个问题有两个解决办法:
1:你只需要它们的相对位置,此时用导入模型的参考点


2:在保存STL文件时,用户指定XYZ的中心和指向,参见这个帖子
Create the structure in the default Solidworks coordinate system and convert it to the Lumerical compatible x/y/z coordinate system before saving the stl file you wish to import.
This is the recommended method. Once you finish the structure in Solidworks, execute the following steps:
a) Click on “Insert”->“Reference Geometry”->"Coordinate System"
b) Define the Lumerical compatible x/y/z coordinate system; set the origin and direction of each axis
c) In the main menu choose “Save As” and set “Save as type” to STL; Click on the “Option” button, and down in the bottom of the pop-up menu, you can select your new coordinate system from the “Output coordinate system” drop down menu.
