00:00:00,880  -->  00:00:03,760
In this lesson, we're taking a brief
look at different

2

00:00:03,760  -->  00:00:06,760
design methodologies and components.

3

00:00:07,800  -->  00:00:10,920
Both top down, bottom up, and hybrid

4

00:00:10,920  -->  00:00:13,960
design methodology is possible
with Autodesk Fusion.

5

00:00:15,120  -->  00:00:18,040
Parts can be designed in context
with other components

6

00:00:18,040  -->  00:00:21,040
within the same file, with a top down
methodology,

7

00:00:21,400  -->  00:00:25,160
as opposed to a bottom up design approach,
which typically

8

00:00:25,160  -->  00:00:28,360
has a lot of files that you x-ref
together into an assembly.

9

00:00:28,840  -->  00:00:32,480
An x-ref is an external reference
that you bring into your work file.

10

00:00:33,800  -->  00:00:38,240
Key benefits with top down modeling,
are the possibility to perform

11

00:00:38,240  -->  00:00:41,120
rapid design iterations,
and the possibility to build

12

00:00:41,120  -->  00:00:45,000
new components in context
with other parts of your design.

13

00:00:46,040  -->  00:00:48,040
You work with internal components.

14

00:00:48,040  -->  00:00:51,040
When you work with a top down design
methodology.

15

00:00:51,320  -->  00:00:56,320
key benefits with bottom up design
methodology are the possibility to reuse

16

00:00:56,320  -->  00:00:57,600
individual components

17

00:00:57,600  -->  00:01:01,680
in different projects, and the possibility
to manage each component separately,

18

00:01:01,680  -->  00:01:05,800
which is helpful when you work
on large and complex designs.

19

00:01:06,960  -->  00:01:08,800
You work with external components.

20

00:01:08,800  -->  00:01:11,800
When you work with a bottom up design
methodology,

21

00:01:12,760  -->  00:01:15,280
you can obviously work
with hybrid scenarios

22

00:01:15,280  -->  00:01:18,840
and combine both a top down
and bottom up design methodology.

23

00:01:19,360  -->  00:01:21,080
Understanding those different design

24

00:01:21,080  -->  00:01:24,400
workflows is essential for your long term
efficiency.

25

00:01:25,040  -->  00:01:28,920
It's considered best practice to create
a new component when you work with

26

00:01:29,040  -->  00:01:30,120
Autodesk Fusion

27

00:01:30,120  -->  00:01:33,600
A component is like a basket
with information

28

00:01:34,040  -->  00:01:37,760
you collect features, design edits,
sketches, geometry, and more

29

00:01:37,760  -->  00:01:40,920
that belong to the component
within the same component.

30

00:01:41,680  -->  00:01:45,000
With this method, you will
thank yourself further down the road.

31

00:01:45,000  -->  00:01:49,760
When you need to adjust or edit
your design, you win

32

00:01:49,760  -->  00:01:51,080
time.

33

00:01:51,080  -->  00:01:55,000
We'll get back to components, assemblies,
joints, bodies, etc.

34

00:01:55,000  -->  00:01:55,960
throughout the course.

35

00:01:55,960  -->  00:02:00,120
But now let's continue
with the goal of building the big picture.

36

00:02:00,640  -->  00:02:01,120
Thank you.
