Hi MarzRX,
Yes, naked edges. I have it shortcuted so you didnt see me type it. Definitely a go to for “why not a solid”

Boolean vs Join

The way i would view it is boolean for solids, join for surfaces (that are edge to edge) if surfaces overlap in the middle somewhere, you would want to “trim” first.

Boolean is actually trim-join-remove rolled into one. So it “CAN” give results with surfaces, but just not the habit to create.
