Building parts in assembly file
Lots of reason, some people like to design in the location of where it's being placed.
You can project geometry of other things around you. For example holes. other features edge.
Helps when you have a tight area, controlled dimensions
Helps for things on compound angles
and the list goes on

If you dont see any reasons to do it..... don't do it!!
Some day, when you learn more you will see all the advantages... and the disadvantages.
Top down modeling is a great way to model assembly's parts, but there's always some disadvantages, and i think for now, you re not preparared to use that.
Stay at the traditional way for now.

It's also a way you can have an adaptive modeling this way. (which I don't recommend)

There's a lot of poor mens... some in the wallet.... others in the head... lol

Here are some examples of Adaptive, however I avoid Adaptive modeling unless it's 100% necessary

I do not know about adaptive modeling.
That's why you have to study and learn more before you think about this advanced themes and make questions that you will not understand.
Keep the traditional modeling. Later you will understand the other mechanisms.
Also i recomend to change the instructor.

I believe you have your answer to the original question
I'd start a new post if you want to ask about a different area .... like adaptive and top down modeling...

Just saying ... because you've now asked about 3 different subjects:
1) Building parts in assembly file
2) Top down modeling
3) Adaptive.
Other people searching about Making a part in an assembly, will have to reach thru all of these subjects.. Just trying to avoid another 4 page / 30 post ..question that was answered on the first page by a few people

When I come across these problems I will start a new post or if you have anything to say about this topic I will start a new post.
Why should we build parts in assembly file when it is possible to import parts from part file?
Why should we import parts from file when it is possible we build parts in assembly?
BECAUSE IN BOTH CASES WE HAVE GOOD THINGS AND BAD THINGS
DEPPENDS ALSO FROM THE KIND OF MODEL YOU NEED (simple assembly, Skeletn model, Top down model, adaptative parts, etc, etc)
ok, it's answered, you can close the topic.
Ps: How can you know if the next instructor it's better????? If he can aswer your simple questions!!! if not... isnt a instructor..
CCarreiras
again you're missing the point.
The point of the forum is to get answers to a question .... about Inventor ..
First you get FAR MORE than that from the this forum...
However if you get an answer to a question, the close it, so others can benefit from it ...like you do. If you have more questions that is something different than the original ..just start a new one ...so again others can benefit.

I know only one reason. For part correctly fit into other part. But it is also not necessary, there is an alternative for that as well. If you have a dimension you can model such a part in part file.
I believe from reading your posts that you are misunderstanding what happens in an assembly file, so I will try to explain in more detail. If this doesn't help, then just ignore it.
- An Inventor assembly is basically just a collection of parts and/or other assemblies, collectively known as components. It contains links to the components, constraints between the components, and a Bill of Material but it does not contain the defining geometry of the components.
- Components are placed into the assembly (not "imported"). Inventor provides for creation and editing of components in the context of the assembly, but there is no fundamental difference— the components are still in their separate respective files and are placed in the assembly in exactly the same way. Editing a component in the assembly allows you to see and measure other components while editing, and it also allows you to project things from another component, creating an adaptive link between these components through the assembly. This can be very powerful but also very risky. As many others have said, it is an advanced topic, so leave it for later.
- Assemblies can also include features that remove material from components (known as Assembly Features). These are created very much like similar features in a part model. Note that these features do not appear in the components themselves, only in the assembly.
- Weldments are a special kind of assembly that have special categories of assembly features: preparations, welds, and machining.
- Assemblies may also contain work features: workplanes, work axes, work points. They appear to be just like the ones in part files, but they're not, they are more like components and are constrained similarly.
There are more intermediate and advanced topics, but I hope this helps to understand the basics of Inventor assembly modeling.
