How do I do diagonal edges on a door frame?

So, I’m trying to build this door from SCP Unity:

I got the edge walls done fine but when I got to the diagonal edges on it, I don’t know how to approach that point. I tried rotating and moving the wedge pieces but they just stuck through the wall and didn’t look that good. How else should I approach this?

Did you try unioning the edges? That’s probably your only other option.

One would imagine like this

and then you union the result so it looks like a single part.

That visualization actually really helps! Tysm
