Can you knock out exterior walls?

[Gravitus]

I am building a space themed base and I'm building a hanger bay. I would like to knock out one of the walls so I can see space. Sorta pretending their is a forcefield...something you'd see in most sci fi movies..... thanks.

In order to do this, I believe you'd have to be building above or below the base and actually build in the other walls.  There are transparent surfaces you might could use for the forcefield appearance.

@EmmySky is correct.  You would need to build outside of the base to accomplish this.  At present, there is (sadly) not an "open sky" texture for walls as there is for ceilings inside the base.

However, there is a way to simulate a starfield...but it’s a lot of work.
