.STL save option not appearing

I'm relatively new to creo, i just got a student license off the website a few days ago. But i have some experience with pro/engineer. On there, whenever you click save as a copy, the stl save option appears in the dropdown menu, however, in creo direct 2.0, I only get 5 options, without .stl there. I really need a stereolithography file, so i can generate a cnc router path in gcode.

Thank you in advance for any advice given.
