Help me create a map

Hi spartans

I made my own halo themed RPG pen&paper game (like dnd and so on…)
I already made sessions with my freinds and let them play on halo maps and own creations with a narrative.

No i want them to board a covenant vessel.
The problem is that i cant find a good layout of a corvette or similar ship. Only the rendering of the CE map of the 3rd level or from Reach.

Could you help me with some images or to create a good drawing? I have someone who would make it a map for my players.
Thx in advance

What kind of layout are you looking for exactly? Are you looking for like the Halo 2 Corvette map that had the sword at the very top. Or the layout of an ENTIRE covenant Corvette with intricate hallways and such.
