Export part of a level as a new mesh


Right I am creating the interior of a spaceship, I have created the hallways and created a blueprint so I can extend and shorten them as I need to. I also have various junction. What I would like to do is export the hallway layout I have already made in its entirety as a mesh so that, I can model other parts to fit the gaps in blender. Is this possible?

It is possible. I do a level block out and export it from unreal to blender and use it as my bases for scale. Have a look below.
