Meaning of profile extrusion

Hello guys,

I am kind of new to grasshopper and completed the task assigned to me and as a feedback, I got: “Although it would have been great to see the profile extrusions”. So I don’t understand what profile extrusion means. Any idea what they want me to do further?

Sorry for the complex workflow as I am kind of new so I tried to do everything with the little knowledge I have with the grasshopper.

I’m assuming this is a window frame, I don’t think you make the frame from a single piece of wood.
