Yes, I was only trying to explain why guides may not be displayed in certain cases: when their insertion point is too far off screen.
Groups and components with real geometry (their edges and faces) are always displayed, even with the local origin not on screen. Just the guides may disappear.
If you have things like beams that are mostly the same, start with one component. If the last 10% (or so) of the geometry of one beam slightly differs from the others, you can make this beam component unique and do the rest of the 10% editing only to this unique component.
p.s. "Make unique" also applies to more than one component, to split a bunch into two groups of components.
