You can open IGES documents in Solid Edge with the Open command. On the Open File dialog box, after you select the IGES document you want to open, click the Options button to display the IGES Import Translation Wizard. You can use the wizard to control how the IGES document is opened in Solid Edge.
To translate multiple IGES files in a single session, use the Seiges.exe file, located in the Solid Edge Version #/program folder. The executable requires Solid Edge be loaded on the machine where the translation occurs.
Note:
When importing assemblies containing more than 600 to 700 part files you need to set the value of the Import DoNotSave=On parameter in the translators ini file to Off. The Import DoNotSave parameter controls whether the Solid Edge part files are created during the translation, or on the initial save of the assembly file. Setting this value to off may take longer to translate but will consume less memory.
