Understanding "Use Duplicates" from spin tool

Support Basics & Interface

Currently on 3.5.1

Documentation for spin tool:

It is still not clear to me. Perhaps someone could explain in layman’s words. For now I’m using this approach as the Array Modifier is doing some weird stuff in a particular build. I’d prefer the latter for a non-destructive workflow.

use a plane… spine it just one step… it will be a quadric thingy… (connected planes)

with use duplicates it will be two planes… (duplicated planes)

I know how to use it, it’s the understanding of what is exactly happening under the hood.

Specially when I can do same thing 4 different ways:

1)Circular Array With Spin Tool
2)With Array Modifier
3)With Object Instances
4)With Duplicating Objects

:question:

One is connecting the spinned objects… the other not…
…or i also don’t get it… (or the quesiton…)

The array modifer is (so to speak) using duplicates… but can connect/join/merge those… bit only if they “almost touch”…

Besides considering nondestructive workflows, is it more CPU intensive?

It’s just recomputing if you change something AFAIK…
