Ah nice, a fellow analogy constructor. I too like to speak in analogies. To answer your question, yes you can model in various ways, you can have each part be its own object or you can model inside a single object. What I typically like to do is model according to the real world. So if I’m modeling a door, the single piece of wood would be one object, the door handle would be a separate object, the hinges separates objects, and so forth.
Also when you are modeling a single object that has lots of intricate parts, usually you have to build up the shape, so in our analogy, it would be stone by stone yes. You start of with basic primitives and you have to shape them to the way you need them and usually that is quad by quad.
But keep watching courses and tutorials, you’ll see the workflows and see the different ways people make things. Mostly it rewires your brain to think how you would model something, the approaches are not like you would make sense of things in real life, since modeling has constraints by its own nature.
