unable to understand the meaning of one of best practices for Large Assembly

Dear inventor users, please help me to understand the meaning of above attached image of best practice.

When you look at that "part" in the Detail View, you are actually looking at the entire assembly, even though the rest of it is "invisible". Why?...Because it's not a simple, base .ipt component you are looking at; the user chose to use the Derive command to import the entire assembly, then only display the one component/part of it for that Detail View (and it also is saved as an .ipt file, so it's not obvious), but all the information for the entire assembly is still there and linked to it, but "in the background and invisible".

sir, can u please elaborate little bit more.

Look at the Derive command; it allows you to derive either an .ipt or an .iam, and the end result is they both will get saved as an .ipt file when you are finished. However, the .ipt that was derived/created from the .iam will stay linked to an entire assembly, so it seems like a regular .ipt in the detail view because you can't "see" the rest of the assembly (but it's still there).

In simple terms:
Detail view consumes/loads the whole IPT in memory >>> the IPT loads up the entire IAM it was derived from in memory. So, even if your detail view looks at a small section of the IPT, you are still loading up a whole assembly in your RAM.

Hi! Yes, I agree with Mitchell and Gabriel. Basically, Inventor is a distributed design tool. It works the best when the geometry is distributed between components. Just like in real life, a machine consists of individual parts assembled together. Derive assembly is a part collecting all geometry from different  subcomponents within the source assembly. The part becomes extremely heavy. Though the number of file to deal with is less, the geometry can be extremely complicated. The resource required to manage such big part can make operations slower.

Many thanks!

Thanks to all...
