Advice how to cut out a square hole.

[Waluigi]

Are you talking about in a window reveal? Cut edge against the window. Good edge against the trim. Same with niches and tiles that happen to be near another wall when the other end of the tile is against the trim. Clear as mud right ?!

I think we need to know where he is fitting this trim before giving
advice, nobody has mentioned a window or niche

 

[Waluigi]

I’m asking where he is putting it and answering where it might be going.

As we all know, there are also many situations where you would have a cut edge against the trim.

Around the window

As above then. That’s how I tend to do it. However it does depend how Plumb the wall is.

Around the window

You will normally have cut edges on the outside of the window, you would then fit your trim inside and then have good edge to trim and
the cut to the frame. As stated by Waluigi
