HI
I'm trying to import a STEP file but when i open in moi all the parts are connected to a single object, if I open in other software the same file have all parts separated.....
I open the INI file but only found the option:
[STEP]
ExportFlattenAssemblies=n

I don't found any other option for the STEP file import, I'm missing something?

thanks ;)
