The SESTL.ini file, found in the Solid Edge Program folder, is used to store the settings defined on the STL Import Options and STL Export Options dialog boxes. When you make a change to a parameter in the dialog box, a new value is saved to the SESTL.ini file. You can use a text editor, such as notepad, to set these parameters. However, if you edit this file, use extreme caution in setting these parameters. Errors made to this file can adversely affect the quality of the translation. The following is a list of parameters found in the SESTL.ini file.
